The data that follows the keyword gitdir: is used as a glob pattern. If the location of the .git directory matches the pattern, the include condition is met.

This is the same as gitdir except that matching is done case-insensitively (e.g. on case-insensitive file systems)

The data that follows the keyword onbranch: is taken to be a pattern with standard globbing wildcards and two additional ones, **/ and /**, that can match multiple path components. If we are in a worktree where the name of the branch that is currently checked out matches the pattern, the include condition is met.

The data that follows this keyword is taken to be a pattern with standard globbing wildcards and two additional ones, **/ and /**, that can match multiple components. The first time this keyword is seen, the rest of the config files will be scanned for remote URLs (without applying any values). If there exists at least one remote URL that matches this pattern, the include condition is met.

When a variable is said to take a boolean value, many synonyms are accepted for true and false; these are all case-insensitive.

The value for many variables that specify various sizes can be suffixed with k, M,…​ to mean "scale the number by 1024", "by 1024x1024", etc.

The value for a variable that takes a color is a list of colors (at most two, one for foreground and one for background) and attributes (as many as you want), separated by spaces.

A variable that takes a pathname value can be given a string that begins with "~/" or "~user/", and the usual tilde expansion happens to such a string: ~/ is expanded to the value of $HOME, and ~user/ to the specified user’s home directory.

Tells git add to continue adding files when some files cannot be added due to indexing errors. Equivalent to the --ignore-errors option of git-add[1]. add.ignore-errors is deprecated, as it does not follow the usual naming convention for configuration variables.

These variables control various optional help messages designed to aid new users. When left unconfigured, Git will give the message alongside instructions on how to squelch it. You can tell Git that you have understood the issue and no longer need a specific help message by setting the corresponding variable to false.

Command aliases for the git[1] command wrapper - e.g. after defining alias.last = cat-file commit HEAD, the invocation git last is equivalent to git cat-file commit HEAD. To avoid confusion and troubles with script usage, aliases that hide existing Git commands are ignored. Arguments are split by spaces, the usual shell quoting and escaping are supported. A quote pair or a backslash can be used to quote them.

If true, git-am will call git-mailsplit for patches in mbox format with parameter --keep-cr. In this case git-mailsplit will not remove \r from lines ending with \r\n. Can be overridden by giving --no-keep-cr from the command line. See git-am[1], git-mailsplit[1].

By default, git am will fail if the patch does not apply cleanly. When set to true, this setting tells git am to fall back on 3-way merge if the patch records the identity of blobs it is supposed to apply to and we have those blobs available locally (equivalent to giving the --3way option from the command line). Defaults to false. See git-am[1].

When set to change, tells git apply to ignore changes in whitespace, in the same way as the --ignore-space-change option. When set to one of: no, none, never, false, it tells git apply to respect all whitespace differences. See git-apply[1].

Tells git apply how to handle whitespace, in the same way as the --whitespace option. See git-apply[1].

A reference to a tree in the repository from which to read attributes, instead of the .gitattributes file in the working tree. If the value does not resolve to a valid tree object, an empty tree is used instead. When the GIT_ATTR_SOURCE environment variable or --attr-source command line option are used, this configuration variable has no effect.

Regular expression used to match reference names. Commits pointed to by references matching this pattern (and meeting the below criteria, like bitmapPseudoMerge.<name>.sampleRate and bitmapPseudoMerge.<name>.threshold) will be considered for inclusion in a pseudo-merge bitmap.

Determines the rate at which consecutive pseudo-merge bitmap groups decrease in size. Must be non-negative. This parameter can be thought of as k in the function f(n) = C * n^-k, where f(n) is the size of the `n`th group.

Determines the proportion of non-bitmapped commits (among reference tips) which are selected for inclusion in an unstable pseudo-merge bitmap. Must be between 0 and 1 (inclusive). The default is 1.

Determines the minimum age of non-bitmapped commits (among reference tips, as above) which are candidates for inclusion in an unstable pseudo-merge bitmap. The default is 1.week.ago.

Determines the maximum number of pseudo-merge commits among which commits may be distributed.

Determines the minimum age of commits (among reference tips, as above, however stable commits are still considered candidates even when they have been covered by a bitmap) which are candidates for a stable a pseudo-merge bitmap. The default is 1.month.ago.

Determines the size (in number of commits) of a stable psuedo-merge bitmap. The default is 512.

Show blank commit object name for boundary commits in git-blame[1]. This option defaults to false.

This determines the coloring scheme to be applied to blame output. It can be repeatedLines, highlightRecent, or none which is the default.

Specifies the format used to output dates in git-blame[1]. If unset the iso format is used. For supported values, see the discussion of the --date option at git-log[1].

Show the author email instead of author name in git-blame[1]. This option defaults to false.

Do not treat root commits as boundaries in git-blame[1]. This option defaults to false.

Ignore revisions listed in the file, one unabbreviated object name per line, in git-blame[1]. Whitespace and comments beginning with # are ignored. This option may be repeated multiple times. Empty file names will reset the list of ignored revisions. This option will be handled before the command line option --ignore-revs-file.

Mark lines that were changed by an ignored revision that we could not attribute to another commit with a * in the output of git-blame[1].

Mark lines that were changed by an ignored revision that we attributed to another commit with a ? in the output of git-blame[1].

Tells git branch, git switch and git checkout to set up new branches so that git-pull[1] will appropriately merge from the starting point branch. Note that even if this option is not set, this behavior can be chosen per-branch using the --track and --no-track options. The valid settings are: false — no automatic setup is done; true — automatic setup is done when the starting point is a remote-tracking branch; always — automatic setup is done when the starting point is either a local branch or remote-tracking branch; inherit — if the starting point has a tracking configuration, it is copied to the new branch; simple — automatic setup is done only when the starting point is a remote-tracking branch and the new branch has the same name as the remote branch. This option defaults to true.

When a new branch is created with git branch, git switch or git checkout that tracks another branch, this variable tells Git to set up pull to rebase instead of merge (see "branch.<name>.rebase"). When never, rebase is never automatically set to true. When local, rebase is set to true for tracked branches of other local branches. When remote, rebase is set to true for tracked branches of remote-tracking branches. When always, rebase will be set to true for all tracking branches. See "branch.autoSetupMerge" for details on how to set up a branch to track another branch. This option defaults to never.

This variable controls the sort ordering of branches when displayed by git-branch[1]. Without the "--sort=<value>" option provided, the value of this variable will be used as the default. See git-for-each-ref[1] field names for valid values.

When on branch <name>, it tells git fetch and git push which remote to fetch from or push to. The remote to push to may be overridden with remote.pushDefault (for all branches). The remote to push to, for the current branch, may be further overridden by branch.<name>.pushRemote. If no remote is configured, or if you are not on any branch and there is more than one remote defined in the repository, it defaults to origin for fetching and remote.pushDefault for pushing. Additionally, . (a period) is the current local repository (a dot-repository), see branch.<name>.merge's final note below.

When on branch <name>, it overrides branch.<name>.remote for pushing. It also overrides remote.pushDefault for pushing from branch <name>. When you pull from one place (e.g. your upstream) and push to another place (e.g. your own publishing repository), you would want to set remote.pushDefault to specify the remote to push to for all branches, and use this option to override it for a specific branch.

Defines, together with branch.<name>.remote, the upstream branch for the given branch. It tells git fetch/git pull/git rebase which branch to merge and can also affect git push (see push.default). When in branch <name>, it tells git fetch the default refspec to be marked for merging in FETCH_HEAD. The value is handled like the remote part of a refspec, and must match a ref which is fetched from the remote given by "branch.<name>.remote". The merge information is used by git pull (which first calls git fetch) to lookup the default branch for merging. Without this option, git pull defaults to merge the first refspec fetched. Specify multiple values to get an octopus merge. If you wish to setup git pull so that it merges into <name> from another branch in the local repository, you can point branch.<name>.merge to the desired branch, and use the relative path setting . (a period) for branch.<name>.remote.

Sets default options for merging into branch <name>. The syntax and supported options are the same as those of git-merge[1], but option values containing whitespace characters are currently not supported.

When true, rebase the branch <name> on top of the fetched branch, instead of merging the default branch from the default remote when "git pull" is run. See "pull.rebase" for doing this in a non branch-specific manner.

Branch description, can be edited with git branch --edit-description. Branch description is automatically added to the format-patch cover letter or request-pull summary.

Specify the command to invoke the specified browser. The specified command is evaluated in shell with the URLs passed as arguments. (See git-web--browse[1].)

Override the path for the given tool that may be used to browse HTML help (see -w option in git-help[1]) or a working repository in gitweb (see git-instaweb[1]).

The bundle.* keys may appear in a bundle list file found via the git clone --bundle-uri option. These keys currently have no effect if placed in a repository config file, though this will change in the future. See the bundle URI design document for more details.

This integer value advertises the version of the bundle list format used by the bundle list. Currently, the only accepted value is 1.

This string value should be either all or any. This value describes whether all of the advertised bundles are required to unbundle a complete understanding of the bundled information (all) or if any one of the listed bundle URIs is sufficient (any).

If this string-valued key exists, then the bundle list is designed to work well with incremental git fetch commands. The heuristic signals that there are additional keys available for each bundle that help determine which subset of bundles the client should download. The only value currently understood is creationToken.

The bundle.<id>.* keys are used to describe a single item in the bundle list, grouped under <id> for identification purposes.

This string value defines the URI by which Git can reach the contents of this <id>. This URI may be a bundle file or another bundle list.

When you run git checkout <something> or git switch <something> and only have one remote, it may implicitly fall back on checking out and tracking e.g. origin/<something>. This stops working as soon as you have more than one remote with a <something> reference. This setting allows for setting the name of a preferred remote that should always win when it comes to disambiguation. The typical use-case is to set this to origin.

Provides the default value for the --guess or --no-guess option in git checkout and git switch. See git-switch[1] and git-checkout[1].

The number of parallel workers to use when updating the working tree. The default is one, i.e. sequential execution. If set to a value less than one, Git will use as many workers as the number of logical cores available. This setting and checkout.thresholdForParallelism affect all commands that perform checkout. E.g. checkout, clone, reset, sparse-checkout, etc.

When running parallel checkout with a small number of files, the cost of subprocess spawning and inter-process communication might outweigh the parallelization gains. This setting allows you to define the minimum number of files for which parallel checkout should be attempted. The default is 100.

A boolean to make git-clean refuse to delete files unless -f is given. Defaults to true.

The name of the remote to create when cloning a repository. Defaults to origin. It can be overridden by passing the --origin command-line option to git-clone[1].

Reject cloning a repository if it is a shallow one; this can be overridden by passing the --reject-shallow option on the command line. See git-clone[1].

If a partial clone filter is provided (see --filter in git-rev-list[1]) and --recurse-submodules is used, also apply the filter to submodules.

A boolean to enable/disable color in hints (e.g. when a push failed, see advice.* for a list). May be set to always, false (or never) or auto (or true), in which case colors are used only when the error output goes to a terminal. If unset, then the value of color.ui is used (auto by default).

Use customized color for hints.

Specify the line annotation color for git blame --color-by-age depending upon the age of the line.

Use the specified color to colorize line annotations for git blame --color-lines, if they come from the same commit as the preceding line. Defaults to cyan.

A boolean to enable/disable color in the output of git-branch[1]. May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. If unset, then the value of color.ui is used (auto by default).

Use customized color for branch coloration. <slot> is one of current (the current branch), local (a local branch), remote (a remote-tracking branch in refs/remotes/), upstream (upstream tracking branch), plain (other refs).

Whether to use ANSI escape sequences to add color to patches. If this is set to always, git-diff[1], git-log[1], and git-show[1] will use color for all patches. If it is set to true or auto, those commands will only use color when output is to the terminal. If unset, then the value of color.ui is used (auto by default).

Use customized color for diff colorization. <slot> specifies which part of the patch to use the specified color, and is one of context (context text - plain is a historical synonym), meta (metainformation), frag (hunk header), func (function in hunk header), old (removed lines), new (added lines), commit (commit headers), whitespace (highlighting whitespace errors), oldMoved (deleted lines), newMoved (added lines), oldMovedDimmed, oldMovedAlternative, oldMovedAlternativeDimmed, newMovedDimmed, newMovedAlternative newMovedAlternativeDimmed (See the <mode> setting of --color-moved in git-diff[1] for details), contextDimmed, oldDimmed, newDimmed, contextBold, oldBold, and newBold (see git-range-diff[1] for details).

Use customized color for git log --decorate output. <slot> is one of branch, remoteBranch, tag, stash or HEAD for local branches, remote-tracking branches, tags, stash and HEAD, respectively and grafted for grafted commits.

When set to always, always highlight matches. When false (or never), never. When set to true or auto, use color only when the output is written to the terminal. If unset, then the value of color.ui is used (auto by default).

Use customized color for grep colorization. <slot> specifies which part of the line to use the specified color, and is one of

When set to always, always use colors for interactive prompts and displays (such as those used by "git-add --interactive" and "git-clean --interactive"). When false (or never), never. When set to true or auto, use colors only when the output is to the terminal. If unset, then the value of color.ui is used (auto by default).

Use customized color for git add --interactive and git clean --interactive output. <slot> may be prompt, header, help or error, for four distinct types of normal output from interactive commands.

A boolean to specify whether auto color modes should colorize output going to the pager. Defaults to true; set this to false if your pager does not understand ANSI color codes.

A boolean to enable/disable color in push errors. May be set to always, false (or never) or auto (or true), in which case colors are used only when the error output goes to a terminal. If unset, then the value of color.ui is used (auto by default).

Use customized color for push errors.

If set, keywords at the start of the line are highlighted. The keywords are "error", "warning", "hint" and "success", and are matched case-insensitively. May be set to always, false (or never) or auto (or true). If unset, then the value of color.ui is used (auto by default).

Use customized color for each remote keyword. <slot> may be hint, warning, success or error which match the corresponding keyword.

A boolean to enable/disable color in the output of git-show-branch[1]. May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. If unset, then the value of color.ui is used (auto by default).

A boolean to enable/disable color in the output of git-status[1]. May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. If unset, then the value of color.ui is used (auto by default).

Use customized color for status colorization. <slot> is one of header (the header text of the status message), added or updated (files which are added but not committed), changed (files which are changed but not added in the index), untracked (files which are not tracked by Git), branch (the current branch), nobranch (the color the no branch warning is shown in, defaulting to red), localBranch or remoteBranch (the local and remote branch names, respectively, when branch and tracking information is displayed in the status short-format), or unmerged (files which have unmerged changes).

A boolean to enable/disable color when pushes are rejected. May be set to always, false (or never) or auto (or true), in which case colors are used only when the error output goes to a terminal. If unset, then the value of color.ui is used (auto by default).

Use customized color when a push was rejected.

This variable determines the default value for variables such as color.diff and color.grep that control the use of color per command family. Its scope will expand as more commands learn configuration to set a default for the --color option. Set it to false or never if you prefer Git commands not to use color unless enabled explicitly with some other configuration or the --color option. Set it to always if you want all output not intended for machine consumption to use color, to true or auto (this is the default since Git 1.8.4) if you want such output to use color when written to the terminal.

Specify whether supported commands should output in columns. This variable consists of a list of tokens separated by spaces or commas:

Specify whether to output branch listing in git branch in columns. See column.ui for details.

Specify the layout when listing items in git clean -i, which always shows files and directories in columns. See column.ui for details.

Specify whether to output untracked files in git status in columns. See column.ui for details.

Specify whether to output tag listings in git tag in columns. See column.ui for details.

This setting overrides the default of the --cleanup option in git commit. See git-commit[1] for details. Changing the default can be useful when you always want to keep lines that begin with the comment character # in your log message, in which case you would do git config commit.cleanup whitespace (note that you will have to remove the help lines that begin with # in the commit log template yourself, if you do this).

A boolean to specify whether all commits should be GPG signed. Use of this option when doing operations such as rebase can result in a large number of commits being signed. It may be convenient to use an agent to avoid typing your GPG passphrase several times.

A boolean to enable/disable inclusion of status information in the commit message template when using an editor to prepare the commit message. Defaults to true.

Specify the pathname of a file to use as the template for new commit messages.

A boolean or int to specify the level of verbosity with git commit. See git-commit[1].

Specifies the type of generation number version to use when writing or reading the commit-graph file. If version 1 is specified, then the corrected commit dates will not be written or read. Defaults to 2.

Specifies the default value for the --max-new-filters option of git commit-graph write (c.f., git-commit-graph[1]).

Deprecated. Equivalent to commitGraph.changedPathsVersion=-1 if true, and commitGraph.changedPathsVersion=0 if false. (If commitGraph.changedPathVersion is also set, commitGraph.changedPathsVersion takes precedence.)

Specifies the version of the changed-path Bloom filters that Git will read and write. May be -1, 0, 1, or 2. Note that values greater than 1 may be incompatible with older versions of Git which do not yet understand those versions. Use caution when operating in a mixed-version environment.

This is only used by git-completion.bash to add or remove commands from the list of completed commands. Normally only porcelain commands and a few select others are completed. You can add more commands, separated by space, in this variable. Prefixing the command with - will remove it from the existing list.

Tells Git if the executable bit of files in the working tree is to be honored.

(Windows-only) If true, mark newly-created directories and files whose name starts with a dot as hidden. If dotGitOnly, only the .git/ directory is hidden, but no other files starting with a dot. The default mode is dotGitOnly.

Internal variable which enables various workarounds to enable Git to work better on filesystems that are not case sensitive, like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing finds "makefile" when Git expects "Makefile", Git will assume it is really the same file, and continue to remember it as "Makefile".

This option is only used by Mac OS implementation of Git. When core.precomposeUnicode=true, Git reverts the unicode decomposition of filenames done by Mac OS. This is useful when sharing a repository between Mac OS and Linux or Windows. (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). When false, file names are handled fully transparent by Git, which is backward compatible with older versions of Git.

If set to true, do not allow checkout of paths that would be considered equivalent to .git on an HFS+ filesystem. Defaults to true on Mac OS, and false elsewhere.

If set to true, do not allow checkout of paths that would cause problems with the NTFS filesystem, e.g. conflict with 8.3 "short" names. Defaults to true on Windows, and false elsewhere.

If set to true, enable the built-in file system monitor daemon for this working directory (git-fsmonitor--daemon[1]).

Otherwise, this variable contains the pathname of the "fsmonitor"
hook command.

Sets the protocol version to be used when invoking the "fsmonitor" hook.

If false, the ctime differences between the index and the working tree are ignored; useful when the inode change time is regularly modified by something outside Git (file system crawlers and some backup systems). See git-update-index[1]. True by default.

If true, the split-index feature of the index will be used. See git-update-index[1]. False by default.

Determines what to do about the untracked cache feature of the index. It will be kept, if this variable is unset or set to keep. It will automatically be added if set to true. And it will automatically be removed, if set to false. Before setting it to true, you should check that mtime is working properly on your system. See git-update-index[1]. keep by default, unless feature.manyFiles is enabled which sets this setting to true by default.

When missing or is set to default, many fields in the stat structure are checked to detect if a file has been modified since Git looked at it. When this configuration variable is set to minimal, sub-second part of mtime and ctime, the uid and gid of the owner of the file, the inode number (and the device number, if Git was compiled to use it), are excluded from the check among these fields, leaving only the whole-second part of mtime (and ctime, if core.trustCtime is set) and the filesize to be checked.

Commands that output paths (e.g. ls-files, diff), will quote "unusual" characters in the pathname by enclosing the pathname in double-quotes and escaping those characters with backslashes in the same way C escapes control characters (e.g. \t for TAB, \n for LF, \\ for backslash) or bytes with values larger than 0x80 (e.g. octal \302\265 for "micro" in UTF-8). If this variable is set to false, bytes higher than 0x80 are not considered "unusual" any more. Double-quotes, backslash and control characters are always escaped regardless of the setting of this variable. A simple space character is not considered "unusual". Many commands can output pathnames completely verbatim using the -z option. The default value is true.

Sets the line ending type to use in the working directory for files that are marked as text (either by having the text attribute set, or by having text=auto and Git auto-detecting the contents as text). Alternatives are lf, crlf and native, which uses the platform’s native line ending. The default value is native. See gitattributes[5] for more information on end-of-line conversion. Note that this value is ignored if core.autocrlf is set to true or input.

If true, makes Git check if converting CRLF is reversible when end-of-line conversion is active. Git will verify if a command modifies a file in the work tree either directly or indirectly. For example, committing a file followed by checking out the same file should yield the original file in the work tree. If this is not the case for the current setting of core.autocrlf, Git will reject the file. The variable can be set to "warn", in which case Git will only warn about an irreversible conversion but continue the operation.

Setting this variable to "true" is the same as setting the text attribute to "auto" on all files and core.eol to "crlf". Set to true if you want to have CRLF line endings in your working directory and the repository has LF line endings. This variable can be set to input, in which case no output conversion is performed.

A comma and/or whitespace separated list of encodings that Git performs UTF-8 round trip checks on if they are used in an working-tree-encoding attribute (see gitattributes[5]). The default value is SHIFT-JIS.

If false, symbolic links are checked out as small plain files that contain the link text. git-update-index[1] and git-add[1] will not change the recorded type to regular file. Useful on filesystems like FAT that do not support symbolic links.

A "proxy command" to execute (as command host port) instead of establishing direct connection to the remote server when using the Git protocol for fetching. If the variable value is in the "COMMAND for DOMAIN" format, the command is applied only on hostnames ending with the specified domain string. This variable may be set multiple times and is matched in the given order; the first match wins.

If this variable is set, git fetch and git push will use the specified command instead of ssh when they need to connect to a remote system. The command is in the same form as the GIT_SSH_COMMAND environment variable and is overridden when the environment variable is set.

If true, Git will avoid using lstat() calls to detect if files have changed by setting the "assume-unchanged" bit for those tracked files which it has updated identically in both the index and working tree.

Instead of the default "symref" format for HEAD and other symbolic reference files, use symbolic links. This is sometimes needed to work with old scripts that expect HEAD to be a symbolic link.

When advertising tips of available history from an alternate, use the shell to execute the specified command instead of git-for-each-ref[1]. The first argument is the absolute path of the alternate. Output must contain one hex object id per line (i.e., the same as produced by git for-each-ref --format='%(objectname)').

When listing references from an alternate, list only references that begin with the given prefix. Prefixes match as if they were given as arguments to git-for-each-ref[1]. To list multiple prefixes, separate them with whitespace. If core.alternateRefsCommand is set, setting core.alternateRefsPrefixes has no effect.

If true this repository is assumed to be bare and has no working directory associated with it. If this is the case a number of commands that require a working directory will be disabled, such as git-add[1] or git-merge[1].

Set the path to the root of the working tree. If GIT_COMMON_DIR environment variable is set, core.worktree is ignored and not used for determining the root of working tree. This can be overridden by the GIT_WORK_TREE environment variable and the --work-tree command-line option. The value can be an absolute path or relative to the path to the .git directory, which is either specified by --git-dir or GIT_DIR, or automatically discovered. If --git-dir or GIT_DIR is specified but none of --work-tree, GIT_WORK_TREE and core.worktree is specified, the current working directory is regarded as the top level of your working tree.

Enable the reflog. Updates to a ref <ref> is logged to the file "$GIT_DIR/logs/<ref>", by appending the new and old SHA-1, the date/time and the reason of the update, but only when the file exists. If this configuration variable is set to true, missing "$GIT_DIR/logs/<ref>" file is automatically created for branch heads (i.e. under refs/heads/), remote refs (i.e. under refs/remotes/), note refs (i.e. under refs/notes/), and the symbolic ref HEAD. If it is set to always, then a missing reflog is automatically created for any ref under refs/.

Internal variable identifying the repository format and layout version.

When group (or true), the repository is made shareable between several users in a group (making sure all the files and objects are group-writable). When all (or world or everybody), the repository will be readable by all users, additionally to being group-shareable. When umask (or false), Git will use permissions reported by umask(2). When 0xxx, where 0xxx is an octal number, files in the repository will have this mode value. 0xxx will override user’s umask value (whereas the other options will only override requested parts of the user’s umask value). Examples: 0660 will make the repo read/write-able for the owner and group, but inaccessible to others (equivalent to group unless umask is e.g. 0022). 0640 is a repository that is group-readable but not group-writable. See git-init[1]. False by default.

If true, Git will warn you if the ref name you passed it is ambiguous and might match multiple refs in the repository. True by default.

An integer -1..9, indicating a default compression level. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If set, this provides a default to other compression variables, such as core.looseCompression and pack.compression.

An integer -1..9, indicating the compression level for objects that are not in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to 1 (best speed).

Number of bytes of a pack file to map into memory in a single mapping operation. Larger window sizes may allow your system to process a smaller number of large pack files more quickly. Smaller window sizes will negatively affect performance due to increased calls to the operating system’s memory manager, but may improve performance when accessing a large number of large pack files.

Maximum number of bytes to map simultaneously into memory from pack files. If Git needs to access more than this many bytes at once to complete an operation it will unmap existing regions to reclaim virtual address space within the process.

Maximum number of bytes per thread to reserve for caching base objects that may be referenced by multiple deltified objects. By storing the entire decompressed base objects in a cache Git is able to avoid unpacking and decompressing frequently used base objects multiple times.

The size of files considered "big", which as discussed below changes the behavior of numerous git commands, as well as how such files are stored within the repository. The default is 512 MiB. Common unit suffixes of k, m, or g are supported.

Specifies the pathname to the file that contains patterns to describe paths that are not meant to be tracked, in addition to .gitignore (per-directory) and .git/info/exclude. Defaults to $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore is used instead. See gitignore[5].

Some commands (e.g. svn and http interfaces) that interactively ask for a password can be told to use an external program given via the value of this variable. Can be overridden by the GIT_ASKPASS environment variable. If not set, fall back to the value of the SSH_ASKPASS environment variable or, failing that, a simple password prompt. The external program shall be given a suitable prompt as command-line argument and write the password on its STDOUT.

In addition to .gitattributes (per-directory) and .git/info/attributes, Git looks into this file for attributes (see gitattributes[5]). Path expansions are made the same way as for core.excludesFile. Its default value is $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/attributes is used instead.

By default Git will look for your hooks in the $GIT_DIR/hooks directory. Set this to different path, e.g. /etc/git/hooks, and Git will try to find your hooks in that directory, e.g. /etc/git/hooks/pre-receive instead of in $GIT_DIR/hooks/pre-receive.

Commands such as commit and tag that let you edit messages by launching an editor use the value of this variable when it is set, and the environment variable GIT_EDITOR is not set. See git-var[1].

Commands such as commit and tag that let you edit messages consider a line that begins with this character commented, and removes them after the editor returns (default #).

[core]
# single character for older versions
commentChar = "#"
# string for newer versions (which will override commentChar
# because it comes later in the file)
commentString = "//"

The length of time, in milliseconds, to retry when trying to lock an individual reference. Value 0 means not to retry at all; -1 means to try indefinitely. Default is 100 (i.e., retry for 100ms).

The length of time, in milliseconds, to retry when trying to lock the packed-refs file. Value 0 means not to retry at all; -1 means to try indefinitely. Default is 1000 (i.e., retry for 1 second).

Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted by the shell. The order of preference is the $GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then the default chosen at compile time (usually less).

A comma separated list of common whitespace problems to notice. git diff will use color.diff.whitespace to highlight them, and git apply --whitespace=error will consider them as errors. You can prefix - to disable any of them (e.g. -trailing-space):

A comma-separated list of components of the repository that should be hardened via the core.fsyncMethod when created or modified. You can disable hardening of any component by prefixing it with a -. Items that are not hardened may be lost in the event of an unclean system shutdown. Unless you have special requirements, it is recommended that you leave this option empty or pick one of committed, added, or all.

A value indicating the strategy Git will use to harden repository data using fsync and related primitives.

This boolean will enable fsync() when writing object files. This setting is deprecated. Use core.fsync instead.

Enable parallel index preload for operations like git diff

Windows-only: comma-separated list of environment variables' names that need to be unset before spawning any other process. Defaults to PERL5LIB to account for the fact that Git for Windows insists on using its own Perl interpreter.

Windows-only: override whether spawned processes inherit only standard file handles (stdin, stdout and stderr) or all handles. Can be auto, true or false. Defaults to auto, which means true on Windows 7 and later, and false on older Windows versions.

You can set this to link, in which case a hardlink followed by a delete of the source are used to make sure that object creation will not overwrite existing objects.

When showing commit messages, also show notes which are stored in the given ref. The ref must be fully qualified. If the given ref does not exist, it is not an error but means that no notes should be printed.

If true, then git will read the commit-graph file (if it exists) to parse the graph structure of commits. Defaults to true. See git-commit-graph[1] for more information.

If set to false, behave as if the --no-replace-objects option was given on the command line. See git[1] and git-replace[1] for more information.

Use the multi-pack-index file to track multiple packfiles using a single index. See git-multi-pack-index[1] for more information. Defaults to true.

Enable "sparse checkout" feature. See git-sparse-checkout[1] for more information.

Enables the "cone mode" of the sparse checkout feature. When the sparse-checkout file contains a limited set of patterns, this mode provides significant performance advantages. The "non-cone mode" can be requested to allow specifying more flexible patterns by setting this variable to false. See git-sparse-checkout[1] for more information.

Set the length object names are abbreviated to. If unspecified or set to "auto", an appropriate value is computed based on the approximate number of packed objects in your repository, which hopefully is enough for abbreviated object names to stay unique for some time. If set to "no", no abbreviation is made and the object names are shown in their full length. The minimum length is 4.

The maximum depth Git is willing to recurse while traversing a tree (e.g., "a/b/cde/f" has a depth of 4). This is a fail-safe to allow Git to abort cleanly, and should not generally need to be adjusted. When Git is compiled with MSVC, the default is 512. Otherwise, the default is 2048.

Specify an external helper to be called when a username or password credential is needed; the helper may consult external storage to avoid prompting the user for the credentials. This is normally the name of a credential helper with possible arguments, but may also be an absolute path with arguments or, if preceded by !, shell commands.

By default, Git and any configured credential helpers will ask for user input when new credentials are required. Many of these helpers will succeed based on stored credentials if those credentials are still valid. To avoid the possibility of user interactivity from Git, set credential.interactive=false. Some credential helpers respect this option as well.

When acquiring credentials, consider the "path" component of an http or https URL to be important. Defaults to false. See gitcredentials[7] for more information.

If no username is set for a network authentication, use this username by default. See credential.<context>.* below, and gitcredentials[7].

Any of the credential.* options above can be applied selectively to some credentials. For example, "credential.https://example.com.username" would set the default username only for https connections to example.com. See gitcredentials[7] for details on how URLs are matched.

Tell git-credential-cache—​daemon to ignore SIGHUP, instead of quitting.

The length of time, in milliseconds, for git-credential-store to retry when trying to lock the credentials file. A value of 0 means not to retry at all; -1 means to try indefinitely. Default is 1000 (i.e., retry for 1s).

When using git diff to compare with work tree files, do not consider stat-only changes as changed. Instead, silently run git update-index --refresh to update the cached stat information for paths whose contents in the work tree match the contents in the index. This option defaults to true. Note that this affects only git diff Porcelain, and not lower level diff commands such as git diff-files.

A comma separated list of --dirstat parameters specifying the default behavior of the --dirstat option to git-diff[1] and friends. The defaults can be overridden on the command line (using --dirstat=<param1,param2,...>). The fallback defaults (when not changed by diff.dirstat) are changes,noncumulative,3. The following parameters are available:

Limit the width of the filename part in --stat output. If set, applies to all commands generating --stat output except format-patch.

Limit the width of the graph part in --stat output. If set, applies to all commands generating --stat output except format-patch.

Generate diffs with <n> lines of context instead of the default of 3. This value is overridden by the -U option.

Show the context between diff hunks, up to the specified number of lines, thereby fusing the hunks that are close to each other. This value serves as the default for the --inter-hunk-context command line option.

If this config variable is set, diff generation is not performed using the internal diff machinery, but using the given command. Can be overridden with the ‘GIT_EXTERNAL_DIFF’ environment variable. The command is called with parameters as described under "git Diffs" in git[1]. Note: if you want to use an external diff program only on a subset of your files, you might want to use gitattributes[5] instead.

If this boolean value is set to true then the diff.external command is expected to return exit code 0 if it considers the input files to be equal or 1 if it considers them to be different, like diff(1). If it is set to false, which is the default, then the command is expected to return exit code 0 regardless of equality. Any other exit code causes Git to report a fatal error.

Sets the default value of --ignore-submodules. Note that this affects only git diff Porcelain, and not lower level diff commands such as git diff-files. git checkout and git switch also honor this setting when reporting uncommitted changes. Setting it to all disables the submodule summary normally shown by git commit and git status when status.submoduleSummary is set unless it is overridden by using the --ignore-submodules command-line option. The git submodule commands are not affected by this setting. By default this is set to untracked so that any untracked submodules are ignored.

If set, git diff uses a prefix pair that is different from the standard "a/" and "b/" depending on what is being compared. When this configuration is in effect, reverse diff output also swaps the order of the prefixes:

If set, git diff does not show any source or destination prefix.

If set, git diff uses this source prefix. Defaults to "a/".

If set, git diff uses this destination prefix. Defaults to "b/".

If set to true, git diff does not show changes outside of the directory and show pathnames relative to the current directory.

File indicating how to order files within a diff. See the -O option to git-diff[1] for details. If diff.orderFile is a relative pathname, it is treated as relative to the top of the working tree.

The number of files to consider in the exhaustive portion of copy/rename detection; equivalent to the git diff option -l. If not set, the default value is currently 1000. This setting has no effect if rename detection is turned off.

Whether and how Git detects renames. If set to "false", rename detection is disabled. If set to "true", basic rename detection is enabled. If set to "copies" or "copy", Git will detect copies, as well. Defaults to true. Note that this affects only git diff Porcelain like git-diff[1] and git-log[1], and not lower level commands such as git-diff-files[1].

A boolean to inhibit the standard behavior of printing a space before each empty output line. Defaults to false.

Specify the format in which differences in submodules are shown. The "short" format just shows the names of the commits at the beginning and end of the range. The "log" format lists the commits in the range like git-submodule[1] summary does. The "diff" format shows an inline diff of the changed contents of the submodule. Defaults to "short".

A POSIX Extended Regular Expression used to determine what is a "word" when performing word-by-word difference calculations. Character sequences that match the regular expression are "words", all other characters are ignorable whitespace.

The custom diff driver command. See gitattributes[5] for details.

If this boolean value is set to true then the diff.<driver>.command command is expected to return exit code 0 if it considers the input files to be equal or 1 if it considers them to be different, like diff(1). If it is set to false, which is the default, then the command is expected to return exit code 0 regardless of equality. Any other exit code causes Git to report a fatal error.

The regular expression that the diff driver should use to recognize the hunk header. A built-in pattern may also be used. See gitattributes[5] for details.

Set this option to true to make the diff driver treat files as binary. See gitattributes[5] for details.

The command that the diff driver should call to generate the text-converted version of a file. The result of the conversion is used to generate a human-readable diff. See gitattributes[5] for details.

The regular expression that the diff driver should use to split words in a line. See gitattributes[5] for details.

Set this option to true to make the diff driver cache the text conversion outputs. See gitattributes[5] for details.

Set this option to false to disable the default heuristics that shift diff hunk boundaries to make patches easier to read.

Choose a diff algorithm. The variants are as follows:

Highlight whitespace errors in the context, old or new lines of the diff. Multiple values are separated by comma, none resets previous values, default reset the list to new and all is a shorthand for old,new,context. The whitespace errors are colored with color.diff.whitespace. The command line option --ws-error-highlight=<kind> overrides this setting.

If set to either a valid <mode> or a true value, moved lines in a diff are colored differently, for details of valid modes see --color-moved in git-diff[1]. If simply set to true the default color mode will be used. When set to false, moved lines are not colored.

When moved lines are colored using e.g. the diff.colorMoved setting, this option controls the <mode> how spaces are treated. For details of valid modes see --color-moved-ws in git-diff[1].

Controls which diff tool is used by git-difftool[1]. This variable overrides the value configured in merge.tool. The list below shows the valid built-in values. Any other value is treated as a custom diff tool and requires that a corresponding difftool.<tool>.cmd variable is defined.

Controls which diff tool is used by git-difftool[1] when the -g/--gui flag is specified. This variable overrides the value configured in merge.guitool. The list below shows the valid built-in values. Any other value is treated as a custom diff tool and requires that a corresponding difftool.<guitool>.cmd variable is defined.

Specify the command to invoke the specified diff tool. The specified command is evaluated in shell with the following variables available: LOCAL is set to the name of the temporary file containing the contents of the diff pre-image and REMOTE is set to the name of the temporary file containing the contents of the diff post-image.

Override the path for the given tool. This is useful in case your tool is not in the PATH.

Exit difftool if the invoked diff tool returns a non-zero exit status.

Prompt before each invocation of the diff tool.

Set true to use the diff.guitool by default (equivalent to specifying the --gui argument), or auto to select diff.guitool or diff.tool depending on the presence of a DISPLAY environment variable value. The default is false, where the --gui argument must be provided explicitly for the diff.guitool to be used.

Specify the hash algorithm to use. The acceptable values are sha1 and sha256. If not specified, sha1 is assumed. It is an error to specify this key unless core.repositoryFormatVersion is 1.

Specify a compatibility hash algorithm to use. The acceptable values are sha1 and sha256. The value specified must be different from the value of extensions.objectFormat. This allows client level interoperability between git repositories whose objectFormat matches this compatObjectFormat. In particular when fully implemented the pushes and pulls from a repository in whose objectFormat matches compatObjectFormat. As well as being able to use oids encoded in compatObjectFormat in addition to oids encoded with objectFormat to locally specify objects.

Specify the ref storage format to use. The acceptable values are:

If enabled, then worktrees will load config settings from the $GIT_DIR/config.worktree file in addition to the $GIT_COMMON_DIR/config file. Note that $GIT_COMMON_DIR and $GIT_DIR are the same for the main working tree, while other working trees have $GIT_DIR equal to $GIT_COMMON_DIR/worktrees/<id>/. The settings in the config.worktree file will override settings from any other config files.

If the number of objects imported by git-fast-import[1] is below this limit, then the objects will be unpacked into loose object files. However, if the number of imported objects equals or exceeds this limit, then the pack will be stored as a pack. Storing the pack from a fast-import can make the import operation complete faster, especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead.

The config settings that start with feature. modify the defaults of a group of other config settings. These groups are created by the Git developer community as recommended defaults and are subject to change. In particular, new config options may be added with different defaults.

Enable config options that are new to Git, and are being considered for future defaults. Config settings included here may be added or removed with each release, including minor version updates. These settings may have unintended interactions since they are so new. Please enable this setting if you are interested in providing feedback on experimental features. The new default values are:

Enable config options that optimize for repos with many files in the working directory. With many files, commands such as git status and git checkout may be slow and these new defaults improve performance:

This option controls whether git fetch (and the underlying fetch in git pull) will recursively fetch into populated submodules. This option can be set either to a boolean value or to on-demand. Setting it to a boolean changes the behavior of fetch and pull to recurse unconditionally into submodules when set to true or to not recurse at all when set to false. When set to on-demand, fetch and pull will only recurse into a populated submodule when its superproject retrieves a commit that updates the submodule’s reference. Defaults to on-demand, or to the value of submodule.recurse if set.

If it is set to true, git-fetch-pack will check all fetched objects. See transfer.fsckObjects for what’s checked. Defaults to false. If not set, the value of transfer.fsckObjects is used instead.

Acts like fsck.<msg-id>, but is used by git-fetch-pack[1] instead of git-fsck[1]. See the fsck.<msg-id> documentation for details.

Acts like fsck.skipList, but is used by git-fetch-pack[1] instead of git-fsck[1]. See the fsck.skipList documentation for details.

If the number of objects fetched over the Git native transfer is below this limit, then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead.

If true, fetch will automatically behave as if the --prune option was given on the command line. See also remote.<name>.prune and the PRUNING section of git-fetch[1].

If true, fetch will automatically behave as if the refs/tags/*:refs/tags/* refspec was provided when pruning, if not set already. This allows for setting both this option and fetch.prune to maintain a 1=1 mapping to upstream refs. See also remote.<name>.pruneTags and the PRUNING section of git-fetch[1].

If true, fetch will attempt to update all available remotes. This behavior can be overridden by passing --no-all or by explicitly specifying one or more remote(s) to fetch from. Defaults to false.

Control how ref update status is printed. Valid values are full and compact. Default value is full. See the OUTPUT section in git-fetch[1] for details.

Control how information about the commits in the local repository is sent when negotiating the contents of the packfile to be sent by the server. Set to "consecutive" to use an algorithm that walks over consecutive commits checking each one. Set to "skipping" to use an algorithm that skips commits in an effort to converge faster, but may result in a larger-than-necessary packfile; or set to "noop" to not send any information at all, which will almost certainly result in a larger-than-necessary packfile, but will skip the negotiation step. Set to "default" to override settings made previously and use the default behaviour. The default is normally "consecutive", but if feature.experimental is true, then the default is "skipping". Unknown values will cause git fetch to error out.

Set to false to enable --no-show-forced-updates in git-fetch[1] and git-pull[1] commands. Defaults to true.

Specifies the maximal number of fetch operations to be run in parallel at a time (submodules, or remotes when the --multiple option of git-fetch[1] is in effect).

Set to true to write a commit-graph after every git fetch command that downloads a pack-file from a remote. Using the --split option, most executions will create a very small commit-graph file on top of the existing commit-graph file(s). Occasionally, these files will merge and the write may take longer. Having an updated commit-graph file helps performance of many Git commands, including git merge-base, git push -f, and git log --graph. Defaults to false.

This value stores a URI for downloading Git object data from a bundle URI before performing an incremental fetch from the origin Git server. This is similar to how the --bundle-uri option behaves in git-clone[1]. git clone --bundle-uri will set the fetch.bundleURI value if the supplied bundle URI contains a bundle list that is organized for incremental fetches.

When using fetch.bundleURI to fetch incrementally from a bundle list that uses the "creationToken" heuristic, this config value stores the maximum creationToken value of the downloaded bundles. This value is used to prevent downloading bundles in the future if the advertised creationToken is not strictly larger than this value.

The command which is used to convert the content of a worktree file to a blob upon checkin. See gitattributes[5] for details.

The command which is used to convert the content of a blob object to a worktree file upon checkout. See gitattributes[5] for details.

Enable multipart/mixed attachments as the default for format-patch. The value can also be a double quoted string which will enable attachments as the default and set the value as the boundary. See the --attach option in git-format-patch[1]. To countermand an earlier value, set it to an empty string.

Provides the default value for the --from option to format-patch. Accepts a boolean value, or a name and email address. If false, format-patch defaults to --no-from, using commit authors directly in the "From:" field of patch mails. If true, format-patch defaults to --from, using your committer identity in the "From:" field of patch mails and including a "From:" field in the body of the patch mail if different. If set to a non-boolean value, format-patch uses that value instead of your committer identity. Defaults to false.

Provides the default value for the --[no-]force-in-body-from option to format-patch. Defaults to false.

A boolean which can enable or disable sequence numbers in patch subjects. It defaults to "auto" which enables it only if there is more than one patch. It can be enabled or disabled for all messages by setting it to "true" or "false". See --numbered option in git-format-patch[1].

Additional email headers to include in a patch to be submitted by mail. See git-format-patch[1].

Additional recipients to include in a patch to be submitted by mail. See the --to and --cc options in git-format-patch[1].

The default for format-patch is to output files with the [PATCH] subject prefix. Use this variable to change that prefix.

The default mode for format-patch to determine which parts of the cover letter will be populated using the branch’s description. See the --cover-from-description option in git-format-patch[1].

The default for format-patch is to output a signature containing the Git version number. Use this variable to change that default. Set this variable to the empty string ("") to suppress signature generation.

Works just like format.signature except the contents of the file specified by this variable will be used as the signature.

The default for format-patch is to output files with the suffix .patch. Use this variable to change that suffix (make sure to include the dot if you want it).

Encode email headers that have non-ASCII characters with "Q-encoding" (described in RFC 2047) for email transmission. Defaults to true.

The default pretty format for log/show/whatchanged command. See git-log[1], git-show[1], git-whatchanged[1].

The default threading style for git format-patch. Can be a boolean value, or shallow or deep. shallow threading makes every mail a reply to the head of the series, where the head is chosen from the cover letter, the --in-reply-to, and the first patch mail, in this order. deep threading makes every mail a reply to the previous one. A true boolean value is the same as shallow, and a false value disables threading.

A boolean value which lets you enable the -s/--signoff option of format-patch by default. Note: Adding the Signed-off-by trailer to a patch should be a conscious act and means that you certify you have the rights to submit this work under the same open source license. Please see the SubmittingPatches document for further discussion.

A boolean that controls whether to generate a cover-letter when format-patch is invoked, but in addition can be set to "auto", to generate a cover-letter only when there’s more than one patch. Default is false.

Set a custom directory to store the resulting files instead of the current working directory. All directory components will be created.

The maximum length of the output filenames generated by the format-patch command; defaults to 64. Can be overridden by the --filename-max-length=<n> command line option.

A boolean value which lets you enable the --base=auto option of format-patch by default. Can also be set to "whenAble" to allow enabling --base=auto if a suitable base is available, but to skip adding base info otherwise without the format dying.

Provides the default value for the --notes option to format-patch. Accepts a boolean value, or a ref which specifies where to get notes. If false, format-patch defaults to --no-notes. If true, format-patch defaults to --notes. If set to a non-boolean value, format-patch defaults to --notes=<ref>, where ref is the non-boolean value. Defaults to false.

[format]
	notes = true
	notes = foo
	notes = false
	notes = bar

A boolean value which enables the robust "mboxrd" format when --stdout is in use to escape "^>+From " lines.

If set, do not show any source or destination prefix in patches. This is equivalent to the diff.noprefix option used by git diff (but which is not respected by format-patch). Note that by setting this, the receiver of any patches you generate will have to apply them using the -p0 option.

During fsck git may find issues with legacy data which wouldn’t be generated by current versions of git, and which wouldn’t be sent over the wire if transfer.fsckObjects was set. This feature is intended to support working with legacy repositories containing such data.

The path to a list of object names (i.e. one unabbreviated SHA-1 per line) that are known to be broken in a non-fatal way and should be ignored. On versions of Git 2.20 and later, comments (#), empty lines, and any leading and trailing whitespace are ignored. Everything but a SHA-1 per line will error out on older versions.

By default, the fsmonitor daemon refuses to work with network-mounted repositories. Setting fsmonitor.allowRemote to true overrides this behavior. Only respected when core.fsmonitor is set to true.

This Mac OS-specific option, if set, specifies the directory in which to create the Unix domain socket used for communication between the fsmonitor daemon and various Git commands. The directory must reside on a native Mac OS filesystem. Only respected when core.fsmonitor is set to true.

The depth parameter used in the delta compression algorithm used by git gc --aggressive. This defaults to 50, which is the default for the --depth option when --aggressive isn’t in use.

The window size parameter used in the delta compression algorithm used by git gc --aggressive. This defaults to 250, which is a much more aggressive window size than the default --window of 10.

When there are approximately more than this many loose objects in the repository, git gc --auto will pack them. Some Porcelain commands use this command to perform a light-weight garbage collection from time to time. The default value is 6700.

When there are more than this many packs that are not marked with *.keep file in the repository, git gc --auto consolidates them into one larger pack. The default value is 50. Setting this to 0 disables it. Setting gc.auto to 0 will also disable this.

Make git gc --auto return immediately and run in the background if the system supports it. Default is true. This config variable acts as a fallback in case maintenance.autoDetach is not set.

If non-zero, all non-cruft packs larger than this limit are kept when git gc is run. This is very similar to --keep-largest-pack except that all non-cruft packs that meet the threshold are kept, not just the largest pack. Defaults to zero. Common unit suffixes of k, m, or g are supported.

If true, then gc will rewrite the commit-graph file when git-gc[1] is run. When using git gc --auto the commit-graph will be updated if housekeeping is required. Default is true. See git-commit-graph[1] for details.

If the file gc.log exists, then git gc --auto will print its content and exit with status zero instead of running unless that file is more than gc.logExpiry old. Default is "1.day". See gc.pruneExpire for more ways to specify its value.

Running git pack-refs in a repository renders it unclonable by Git versions prior to 1.5.1.2 over dumb transports such as HTTP. This variable determines whether git gc runs git pack-refs. This can be set to notbare to enable it within all non-bare repos or it can be set to a boolean value. The default is true.

Store unreachable objects in a cruft pack (see git-repack[1]) instead of as loose objects. The default is true.

Limit the size of new cruft packs when repacking. When specified in addition to --max-cruft-size, the command line option takes priority. See the --max-cruft-size option of git-repack[1].

When git gc is run, it will call prune --expire 2.weeks.ago (and repack --cruft --cruft-expiration 2.weeks.ago if using cruft packs via gc.cruftPacks or --cruft). Override the grace period with this config variable. The value "now" may be used to disable this grace period and always prune unreachable objects immediately, or "never" may be used to suppress pruning. This feature helps prevent corruption when git gc runs concurrently with another process writing to the repository; see the "NOTES" section of git-gc[1].

When git gc is run, it calls git worktree prune --expire 3.months.ago. This config variable can be used to set a different grace period. The value "now" may be used to disable the grace period and prune $GIT_DIR/worktrees immediately, or "never" may be used to suppress pruning.

git reflog expire removes reflog entries older than this time; defaults to 90 days. The value "now" expires all entries immediately, and "never" suppresses expiration altogether. With "<pattern>" (e.g. "refs/stash") in the middle the setting applies only to the refs that match the <pattern>.

git reflog expire removes reflog entries older than this time and are not reachable from the current tip; defaults to 30 days. The value "now" expires all entries immediately, and "never" suppresses expiration altogether. With "<pattern>" (e.g. "refs/stash") in the middle, the setting applies only to the refs that match the <pattern>.

When considering whether or not to remove an object (either when generating a cruft pack or storing unreachable objects as loose), use the shell to execute the specified command(s). Interpret their output as object IDs which Git will consider as "recent", regardless of their age. By treating their mtimes as "now", any objects (and their descendants) mentioned in the output will be kept regardless of their true age.

When repacking, use the specified filter to move certain objects into a separate packfile. See the --filter=<filter-spec> option of git-repack[1].

When repacking and using a filter, see gc.repackFilter, the specified location will be used to create the packfile containing the filtered out objects. WARNING: The specified location should be accessible, using for example the Git alternates mechanism, otherwise the repo could be considered corrupt by Git as it might not be able to access the objects in that packfile. See the --filter-to=<dir> option of git-repack[1] and the objects/info/alternates section of gitrepository-layout[5].

Records of conflicted merge you resolved earlier are kept for this many days when git rerere gc is run. You can also use more human-readable "1.month.ago", etc. The default is 60 days. See git-rerere[1].

Records of conflicted merge you have not resolved are kept for this many days when git rerere gc is run. You can also use more human-readable "1.month.ago", etc. The default is 15 days. See git-rerere[1].

Append this string to each commit message. Set to empty string to disable this feature. Defaults to "via git-CVS emulator".

Whether the CVS server interface is enabled for this repository. See git-cvsserver[1].

Path to a log file where the CVS server interface well…​ logs various stuff. See git-cvsserver[1].

If true, the server will look up the end-of-line conversion attributes for files to determine the -k modes to use. If the attributes force Git to treat a file as text, the -k mode will be left blank so CVS clients will treat it as text. If they suppress text conversion, the file will be set with -kb mode, which suppresses any newline munging the client might otherwise do. If the attributes do not allow the file type to be determined, then gitcvs.allBinary is used. See gitattributes[5].

This is used if gitcvs.usecrlfattr does not resolve the correct -kb mode to use. If true, all unresolved files are sent to the client in mode -kb. This causes the client to treat them as binary files, which suppresses any newline munging it otherwise might do. Alternatively, if it is set to "guess", then the contents of the file are examined to decide if it is binary, similar to core.autocrlf.

Database used by git-cvsserver to cache revision information derived from the Git repository. The exact meaning depends on the used database driver, for SQLite (which is the default driver) this is a filename. Supports variable substitution (see git-cvsserver[1] for details). May not contain semicolons (;). Default: %Ggitcvs.%m.sqlite

Used Perl DBI driver. You can specify any available driver for this here, but it might not work. git-cvsserver is tested with DBD::SQLite, reported to work with DBD::Pg, and reported not to work with DBD::mysql. Experimental feature. May not contain double colons (:). Default: SQLite. See git-cvsserver[1].

Database user and password. Only useful if setting gitcvs.dbDriver, since SQLite has no concept of database users and/or passwords. gitcvs.dbUser supports variable substitution (see git-cvsserver[1] for details).

Database table name prefix. Prepended to the names of any database tables used, allowing a single database to be used for several repositories. Supports variable substitution (see git-cvsserver[1] for details). Any non-alphabetic characters will be replaced with underscores.

See gitweb[1] for description.

See gitweb.conf[5] for description.

Use this custom program instead of "gpg" found on $PATH when making or verifying a PGP signature. The program must support the same command-line interface as GPG, namely, to verify a detached signature, "gpg --verify $signature - <$file" is run, and the program is expected to signal a good signature by exiting with code 0. To generate an ASCII-armored detached signature, the standard input of "gpg -bsau $key" is fed with the contents to be signed, and the program is expected to send the result to its standard output.

Specifies which key format to use when signing with --gpg-sign. Default is "openpgp". Other possible values are "x509", "ssh".

Use this to customize the program used for the signing format you chose. (see gpg.program and gpg.format) gpg.program can still be used as a legacy synonym for gpg.openpgp.program. The default value for gpg.x509.program is "gpgsm" and gpg.ssh.program is "ssh-keygen".

Specifies a minimum trust level for signature verification. If this option is unset, then signature verification for merge operations requires a key with at least marginal trust. Other operations that perform signature verification require a key with at least undefined trust. Setting this option overrides the required trust-level for all operations. Supported values, in increasing order of significance:

This command will be run when user.signingkey is not set and a ssh signature is requested. On successful exit a valid ssh public key prefixed with key:: is expected in the first line of its output. This allows for a script doing a dynamic lookup of the correct public key when it is impractical to statically configure user.signingKey. For example when keys or SSH Certificates are rotated frequently or selection of the right key depends on external factors unknown to git.

A file containing ssh public keys which you are willing to trust. The file consists of one or more lines of principals followed by an ssh public key. e.g.: user1@example.com,user2@example.com ssh-rsa AAAAX1... See ssh-keygen(1) "ALLOWED SIGNERS" for details. The principal is only used to identify the key and is available when verifying a signature.

Either a SSH KRL or a list of revoked public keys (without the principal prefix). See ssh-keygen(1) for details. If a public key is found in this file then it will always be treated as having trust level "never" and signatures will show as invalid.

If set to true, enable -n option by default.

If set to true, enable the --column option by default.

Set the default matching behavior. Using a value of basic, extended, fixed, or perl will enable the --basic-regexp, --extended-regexp, --fixed-strings, or --perl-regexp option accordingly, while the value default will use the grep.extendedRegexp option to choose between basic and extended.

If set to true, enable --extended-regexp option by default. This option is ignored when the grep.patternType option is set to a value other than default.

Number of grep worker threads to use. If unset (or set to 0), Git will use as many threads as the number of logical cores available.

If set to true, enable --full-name option by default.

If set to true, fall back to git grep --no-index if git grep is executed outside of a git repository. Defaults to false.

Defines how wide the commit message window is in the git-gui[1]. "75" is the default.

Specifies how many context lines should be used in calls to diff made by the git-gui[1]. The default is "5".

Determines if git-gui[1] shows untracked files in the file list. The default is "true".

Specifies the default character encoding to use for displaying of file contents in git-gui[1] and gitk[1]. It can be overridden by setting the encoding attribute for relevant files (see gitattributes[5]). If this option is not set, the tools default to the locale encoding.

Determines if new branches created with git-gui[1] should default to tracking remote branches with matching names or not. Default: "false".

Is used as a suggested name when creating new branches using the git-gui[1].

"true" if git-gui[1] should prune remote-tracking branches when performing a fetch. The default value is "false".

Determines if git-gui[1] should trust the file modification timestamp or not. By default the timestamps are not trusted.

Specifies the dictionary used for spell checking commit messages in the git-gui[1]. When set to "none" spell checking is turned off.

If true, git gui blame uses -C instead of -C -C for original location detection. It makes blame significantly faster on huge repositories at the expense of less thorough copy detection.

Specifies the threshold to use in git gui blame original location detection, measured in alphanumeric characters. See the git-blame[1] manual for more information on copy detection.

Specifies the radius of history context in days to show in gitk[1] for the selected commit, when the Show History Context menu item is invoked from git gui blame. If this variable is set to zero, the whole history is shown.

Specifies the shell command line to execute when the corresponding item of the git-gui[1] Tools menu is invoked. This option is mandatory for every tool. The command is executed from the root of the working directory, and in the environment it receives the name of the tool as GIT_GUITOOL, the name of the currently selected file as FILENAME, and the name of the current branch as CUR_BRANCH (if the head is detached, CUR_BRANCH is empty).

Run the tool only if a diff is selected in the GUI. It guarantees that FILENAME is not empty.

Run the command silently, without creating a window to display its output.

Don’t rescan the working directory for changes after the tool finishes execution.

Show a confirmation dialog before actually running the tool.

Request a string argument from the user, and pass it to the tool through the ARGS environment variable. Since requesting an argument implies confirmation, the confirm option has no effect if this is enabled. If the option is set to true, yes, or 1, the dialog uses a built-in generic prompt; otherwise the exact value of the variable is used.

Request a single valid revision from the user, and set the REVISION environment variable. In other aspects this option is similar to argPrompt, and can be used together with it.

Show only unmerged branches in the revPrompt subdialog. This is useful for tools similar to merge or rebase, but not for things like checkout or reset.

Specifies the title to use for the prompt dialog. The default is the tool name.

Specifies the general prompt string to display at the top of the dialog, before subsections for argPrompt and revPrompt. The default value includes the actual command.

Specify the browser that will be used to display help in the web format. See git-help[1].

Override the default help format used by git-help[1]. Values man, info, web and html are supported. man is the default. web and html are the same.

If git detects typos and can identify exactly one valid command similar to the error, git will try to suggest the correct command or even run the suggestion automatically. Possible config values are:

Specify the path where the HTML documentation resides. File system paths and URLs are supported. HTML pages will be prefixed with this path when help is displayed in the web format. This defaults to the documentation path of your Git installation.

Override the HTTP proxy, normally configured using the http_proxy, https_proxy, and all_proxy environment variables (see curl(1)). In addition to the syntax understood by curl, it is possible to specify a proxy string with a user name but no password, in which case git will attempt to acquire one in the same way it does for other credentials. See gitcredentials[7] for more information. The syntax thus is [protocol://][user[:password]@]proxyhost[:port][/path]. This can be overridden on a per-remote basis; see remote.<name>.proxy

Set the method with which to authenticate against the HTTP proxy. This only takes effect if the configured proxy string contains a user name part (i.e. is of the form user@host or user@host:port). This can be overridden on a per-remote basis; see remote.<name>.proxyAuthMethod. Both can be overridden by the GIT_HTTP_PROXY_AUTHMETHOD environment variable. Possible values are:

The pathname of a file that stores a client certificate to use to authenticate with an HTTPS proxy. Can be overridden by the GIT_PROXY_SSL_CERT environment variable.

The pathname of a file that stores a private key to use to authenticate with an HTTPS proxy. Can be overridden by the GIT_PROXY_SSL_KEY environment variable.

Enable Git’s password prompt for the proxy SSL certificate. Otherwise OpenSSL will prompt the user, possibly many times, if the certificate or private key is encrypted. Can be overridden by the GIT_PROXY_SSL_CERT_PASSWORD_PROTECTED environment variable.

Pathname to the file containing the certificate bundle that should be used to verify the proxy with when using an HTTPS proxy. Can be overridden by the GIT_PROXY_SSL_CAINFO environment variable.

Attempt authentication without seeking a username or password. This can be used to attempt GSS-Negotiate authentication without specifying a username in the URL, as libcurl normally requires a username for authentication.

Attempt authentication without first making an unauthenticated attempt and receiving a 401 response. This can be used to ensure that all requests are authenticated. If http.emptyAuth is set to true, this value has no effect.

Control GSSAPI credential delegation. The delegation is disabled by default in libcurl since version 7.21.7. Set parameter to tell the server what it is allowed to delegate when it comes to user credentials. Used with GSS/kerberos. Possible values are:

Pass an additional HTTP header when communicating with a server. If more than one such entry exists, all of them are added as extra headers. To allow overriding the settings inherited from the system config, an empty value will reset the extra headers to the empty list.

The pathname of a file containing previously stored cookie lines, which should be used in the Git http session, if they match the server. The file format of the file to read cookies from should be plain HTTP headers or the Netscape/Mozilla cookie file format (see curl(1)). Set it to an empty string, to accept only new cookies from the server and send them back in successive requests within same connection. NOTE that the file specified with http.cookieFile is used only as input unless http.saveCookies is set.

If set, store cookies received during requests to the file specified by http.cookieFile. Has no effect if http.cookieFile is unset, or set to an empty string.

Use the specified HTTP protocol version when communicating with a server. If you want to force the default. The available and default version depend on libcurl. Currently the possible values of this option are:

Hostname resolution information that will be used first by libcurl when sending HTTP requests. This information should be in one of the following formats:

The SSL version to use when negotiating an SSL connection, if you want to force the default. The available and default version depend on whether libcurl was built against NSS or OpenSSL and the particular configuration of the crypto library in use. Internally this sets the CURLOPT_SSL_VERSION option; see the libcurl documentation for more details on the format of this option and for the ssl version supported. Currently the possible values of this option are:

A list of SSL ciphers to use when negotiating an SSL connection. The available ciphers depend on whether libcurl was built against NSS or OpenSSL and the particular configuration of the crypto library in use. Internally this sets the CURLOPT_SSL_CIPHER_LIST option; see the libcurl documentation for more details on the format of this list.

Whether to verify the SSL certificate when fetching or pushing over HTTPS. Defaults to true. Can be overridden by the GIT_SSL_NO_VERIFY environment variable.

File containing the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CERT environment variable.

File containing the SSL private key when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_KEY environment variable.

Enable Git’s password prompt for the SSL certificate. Otherwise OpenSSL will prompt the user, possibly many times, if the certificate or private key is encrypted. Can be overridden by the GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

File containing the certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable.

Path containing files with the CA certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable.

Name of the SSL backend to use (e.g. "openssl" or "schannel"). This option is ignored if cURL lacks support for choosing the SSL backend at runtime.

Used to enforce or disable certificate revocation checks in cURL when http.sslBackend is set to "schannel". Defaults to true if unset. Only necessary to disable this if Git consistently errors and the message is about checking the revocation status of a certificate. This option is ignored if cURL lacks support for setting the relevant SSL option at runtime.

As of cURL v7.60.0, the Secure Channel backend can use the certificate bundle provided via http.sslCAInfo, but that would override the Windows Certificate Store. Since this is not desirable by default, Git will tell cURL not to use that bundle by default when the schannel backend was configured via http.sslBackend, unless http.schannelUseSSLCAInfo overrides this behavior.

Public key of the https service. It may either be the filename of a PEM or DER encoded public key file or a string starting with sha256// followed by the base64 encoded sha256 hash of the public key. See also libcurl CURLOPT_PINNEDPUBLICKEY. git will exit with an error if this option is set but not supported by cURL.

Attempt to use AUTH SSL/TLS and encrypted data transfers when connecting via regular FTP protocol. This might be needed if the FTP server requires it for security reasons or you wish to connect securely whenever remote FTP server supports it. Default is false since it might trigger certificate verification errors on misconfigured servers.

How many HTTP requests to launch in parallel. Can be overridden by the GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.

The number of curl sessions (counted across slots) to be kept across requests. They will not be ended with curl_easy_cleanup() until http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this value will be capped at 1. Defaults to 1.

Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests.

If the HTTP transfer speed, in bytes per second, is less than http.lowSpeedLimit for longer than http.lowSpeedTime seconds, the transfer is aborted. Can be overridden by the GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment variables.

A boolean which disables using of EPSV ftp command by curl. This can be helpful with some "poor" ftp servers which don’t support EPSV mode. Can be overridden by the GIT_CURL_FTP_NO_EPSV environment variable. Default is false (curl will use EPSV).

The HTTP USER_AGENT string presented to an HTTP server. The default value represents the version of the Git client such as git/1.7.1. This option allows you to override this value to a more common value such as Mozilla/4.0. This may be necessary, for instance, if connecting through a firewall that restricts HTTP connections to a set of common USER_AGENT strings (but not including those like git/1.7.1). Can be overridden by the GIT_HTTP_USER_AGENT environment variable.

Whether git should follow HTTP redirects. If set to true, git will transparently follow any redirect issued by a server it encounters. If set to false, git will treat all redirects as errors. If set to initial, git will follow redirects only for the initial request to a remote, but not for subsequent follow-up HTTP requests. Since git uses the redirected URL as the base for the follow-up requests, this is generally sufficient. The default is initial.

Any of the http.* options above can be applied selectively to some URLs. For a config key to match a URL, each element of the config key is compared to that of the URL, in the following order:

Character encoding the commit messages are stored in; Git itself does not care per se, but this information is necessary e.g. when importing commits from emails or in the gitk graphical history browser (and possibly in other places in the future or in other porcelains). See e.g. git-mailinfo[1]. Defaults to utf-8.

Character encoding the commit messages are converted to when running git log and friends.

The folder to drop the mails into, which is typically the Drafts folder. For example: "INBOX.Drafts", "INBOX/Drafts" or "[Gmail]/Drafts". Required.

Command used to set up a tunnel to the IMAP server through which commands will be piped instead of using a direct network connection to the server. Required when imap.host is not set.

A URL identifying the server. Use an imap:// prefix for non-secure connections and an imaps:// prefix for secure connections. Ignored when imap.tunnel is set, but required otherwise.

The username to use when logging in to the server.

The password to use when logging in to the server.

An integer port number to connect to on the server. Defaults to 143 for imap:// hosts and 993 for imaps:// hosts. Ignored when imap.tunnel is set.

A boolean to enable/disable verification of the server certificate used by the SSL/TLS connection. Default is true. Ignored when imap.tunnel is set.

A boolean to enable/disable the use of html encoding when sending a patch. An html encoded patch will be bracketed with <pre> and have a content type of text/html. Ironically, enabling this option causes Thunderbird to send the patch as a plain/text, format=fixed email. Default is false.

Specify the authentication method for authenticating with the IMAP server. If Git was built with the NO_CURL option, or if your curl version is older than 7.34.0, or if you’re running git-imap-send with the --no-curl option, the only supported method is CRAM-MD5. If this is not set then git imap-send uses the basic IMAP plaintext LOGIN command.

Special variables to include other configuration files. See the "CONFIGURATION FILE" section in the main git-config[1] documentation, specifically the "Includes" and "Conditional Includes" subsections.

Specifies whether the index file should include an "End Of Index Entry" section. This reduces index load time on multiprocessor machines but produces a message "ignoring EOIE extension" when reading the index using Git versions before 2.20. Defaults to true if index.threads has been explicitly enabled, false otherwise.

Specifies whether the index file should include an "Index Entry Offset Table" section. This reduces index load time on multiprocessor machines but produces a message "ignoring IEOT extension" when reading the index using Git versions before 2.20. Defaults to true if index.threads has been explicitly enabled, false otherwise.

When enabled, write the index using sparse-directory entries. This has no effect unless core.sparseCheckout and core.sparseCheckoutCone are both enabled. Defaults to false.

Specifies the number of threads to spawn when loading the index. This is meant to reduce index load time on multiprocessor machines. Specifying 0 or true will cause Git to auto-detect the number of CPUs and set the number of threads accordingly. Specifying 1 or false will disable multithreading. Defaults to true.

Specify the version with which new index files should be initialized. This does not affect existing repositories. If feature.manyFiles is enabled, then the default is 4.

When enabled, do not compute the trailing hash for the index file. This accelerates Git commands that manipulate the index, such as git add, git commit, or git status. Instead of storing the checksum, write a trailing set of bytes with value zero, indicating that the computation was skipped.

Specify the directory from which templates will be copied. (See the "TEMPLATE DIRECTORY" section of git-init[1].)

Allows overriding the default branch name e.g. when initializing a new repository.

Allows overriding the default object format for new repositories. See --object-format= in git-init[1]. Both the command line option and the GIT_DEFAULT_HASH environment variable take precedence over this config.

Allows overriding the default ref storage format for new repositories. See --ref-format= in git-init[1]. Both the command line option and the GIT_DEFAULT_REF_FORMAT environment variable take precedence over this config.

Specify the program that will be used to browse your working repository in gitweb. See git-instaweb[1].

The HTTP daemon command-line to start gitweb on your working repository. See git-instaweb[1].

If true the web server started by git-instaweb[1] will be bound to the local IP (127.0.0.1).

The default module path for git-instaweb[1] to use instead of /usr/lib/apache2/modules. Only used if httpd is Apache.

The port number to bind the gitweb httpd to. See git-instaweb[1].

When set to true, allow the user to provide one-letter input with a single key (i.e., without hitting the Enter key) in interactive commands. This is currently used by the --patch mode of git-add[1], git-checkout[1], git-restore[1], git-commit[1], git-reset[1], and git-stash[1].

When an interactive command (such as git add --patch) shows a colorized diff, git will pipe the diff through the shell command defined by this configuration variable. The command may mark up the diff further for human consumption, provided that it retains a one-to-one correspondence with the lines in the original diff. Defaults to disabled (no filtering).

If true, makes git-log[1], git-show[1], and git-whatchanged[1] assume --abbrev-commit. You may override this option with --no-abbrev-commit.

Set the default date-time mode for the log command. Setting a value for log.date is similar to using git log's --date option. See git-log[1] for details.

Print out the ref names of any commits that are shown by the log command. If short is specified, the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ will not be printed. If full is specified, the full ref name (including prefix) will be printed. If auto is specified, then if the output is going to a terminal, the ref names are shown as if short were given, otherwise no ref names are shown. This is the same as the --decorate option of the git log.

By default, git log only shows decorations for certain known ref namespaces. If all is specified, then show all refs as decorations.

Exclude the specified patterns from the log decorations. This is similar to the --decorate-refs-exclude command-line option, but the config option can be overridden by the --decorate-refs option.

Set diff format to be used when --diff-merges=on is specified, see --diff-merges in git-log[1] for details. Defaults to separate.

If true, git log will act as if the --follow option was used when a single <path> is given. This has the same limitations as --follow, i.e. it cannot be used to follow multiple files and does not work well on non-linear history.

A list of colors, separated by commas, that can be used to draw history lines in git log --graph.

If true, the initial commit will be shown as a big creation event. This is equivalent to a diff against an empty tree. Tools like git-log[1] or git-whatchanged[1], which normally hide the root commit will now show it. True by default.

If true, makes git-log[1], git-show[1], and git-whatchanged[1] assume --show-signature.

If true, makes git-log[1], git-show[1], and git-whatchanged[1] assume --use-mailmap, otherwise assume --no-use-mailmap. True by default.

May be "advertise" (the default), "allow", or "ignore". If "advertise", the server will respond to the client sending "unborn" (as described in gitprotocol-v2[5]) and will advertise support for this feature during the protocol v2 capability advertisement. "allow" is the same as "advertise" except that the server will not advertise support for this feature; this is useful for load-balanced servers that cannot be updated atomically (for example), since the administrator could configure "allow", then after a delay, configure "advertise".

If true, makes git-mailinfo[1] (and therefore git-am[1]) act by default as if the --scissors option was provided on the command-line. When active, this feature removes everything from the message body before a scissors line (i.e. consisting mainly of ">8", "8<" and "-").

The location of an augmenting mailmap file. The default mailmap, located in the root of the repository, is loaded first, then the mailmap file pointed to by this variable. The location of the mailmap file may be in a repository subdirectory, or somewhere outside of the repository itself. See git-shortlog[1] and git-blame[1].

Like mailmap.file, but consider the value as a reference to a blob in the repository. If both mailmap.file and mailmap.blob are given, both are parsed, with entries from mailmap.file taking precedence. In a bare repository, this defaults to HEAD:.mailmap. In a non-bare repository, it defaults to empty.

This boolean config option controls whether some commands run git maintenance run --auto after doing their normal work. Defaults to true.

Many Git commands trigger automatic maintenance after they have written data into the repository. This boolean config option controls whether this automatic maintenance shall happen in the foreground or whether the maintenance process shall detach and continue to run in the background.

This string config option provides a way to specify one of a few recommended schedules for background maintenance. This only affects which tasks are run during git maintenance run --schedule=X commands, provided no --task=<task> arguments are provided. Further, if a maintenance.<task>.schedule config value is set, then that value is used instead of the one provided by maintenance.strategy. The possible strategy strings are:

This boolean config option controls whether the maintenance task with name <task> is run when no --task option is specified to git maintenance run. These config values are ignored if a --task option exists. By default, only maintenance.gc.enabled is true.

This config option controls whether or not the given <task> runs during a git maintenance run --schedule=<frequency> command. The value must be one of "hourly", "daily", or "weekly".

This integer config option controls how often the commit-graph task should be run as part of git maintenance run --auto. If zero, then the commit-graph task will not run with the --auto option. A negative value will force the task to run every time. Otherwise, a positive value implies the command should run when the number of reachable commits that are not in the commit-graph file is at least the value of maintenance.commit-graph.auto. The default value is 100.

This integer config option controls how often the loose-objects task should be run as part of git maintenance run --auto. If zero, then the loose-objects task will not run with the --auto option. A negative value will force the task to run every time. Otherwise, a positive value implies the command should run when the number of loose objects is at least the value of maintenance.loose-objects.auto. The default value is 100.

This integer config option controls how often the incremental-repack task should be run as part of git maintenance run --auto. If zero, then the incremental-repack task will not run with the --auto option. A negative value will force the task to run every time. Otherwise, a positive value implies the command should run when the number of pack-files not in the multi-pack-index is at least the value of maintenance.incremental-repack.auto. The default value is 10.

Specify the programs that may be used to display help in the man format. See git-help[1].

Specify the command to invoke the specified man viewer. The specified command is evaluated in shell with the man page passed as an argument. (See git-help[1].)

Override the path for the given tool that may be used to display help in the man format. See git-help[1].

Specify the style in which conflicted hunks are written out to working tree files upon merge. The default is "merge", which shows a <<<<<<< conflict marker, changes made by one side, a ======= marker, changes made by the other side, and then a >>>>>>> marker. An alternate style, "diff3", adds a ||||||| marker and the original text before the ======= marker. The "merge" style tends to produce smaller conflict regions than diff3, both because of the exclusion of the original text, and because when a subset of lines match on the two sides, they are just pulled out of the conflict region. Another alternate style, "zdiff3", is similar to diff3 but removes matching lines on the two sides from the conflict region when those matching lines appear near either the beginning or end of a conflict region.

If merge is called without any commit argument, merge the upstream branches configured for the current branch by using their last observed values stored in their remote-tracking branches. The values of the branch.<current branch>.merge that name the branches at the remote named by branch.<current branch>.remote are consulted, and then they are mapped via remote.<remote>.fetch to their corresponding remote-tracking branches, and the tips of these tracking branches are merged. Defaults to true.

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded. When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line). When set to only, only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

If true, this is equivalent to the --verify-signatures command line option. See git-merge[1] for details.

In addition to branch names, populate the log message with the branch description text associated with them. Defaults to false.

In addition to branch names, populate the log message with at most the specified number of one-line descriptions from the actual commits that are being merged. Defaults to false, and true is a synonym for 20.

By adding a glob that matches the names of integration branches to this multi-valued configuration variable, the default merge message computed for merges into these integration branches will omit "into <branch name>" from its title.

The number of files to consider in the exhaustive portion of rename detection during a merge. If not specified, defaults to the value of diff.renameLimit. If neither merge.renameLimit nor diff.renameLimit are specified, currently defaults to 7000. This setting has no effect if rename detection is turned off.

Whether Git detects renames. If set to "false", rename detection is disabled. If set to "true", basic rename detection is enabled. Defaults to the value of diff.renames.

Whether Git detects directory renames, affecting what happens at merge time to new files added to a directory on one side of history when that directory was renamed on the other side of history. If merge.directoryRenames is set to "false", directory rename detection is disabled, meaning that such new files will be left behind in the old directory. If set to "true", directory rename detection is enabled, meaning that such new files will be moved into the new directory. If set to "conflict", a conflict will be reported for such paths. If merge.renames is false, merge.directoryRenames is ignored and treated as false. Defaults to "conflict".

Tell Git that canonical representation of files in the repository has changed over time (e.g. earlier commits record text files with CRLF line endings, but recent ones use LF line endings). In such a repository, Git can convert the data recorded in commits to a canonical form before performing a merge to reduce unnecessary conflicts. For more information, see section "Merging branches with differing checkin/checkout attributes" in gitattributes[5].

Whether to print the diffstat between ORIG_HEAD and the merge result at the end of the merge. True by default.

When set to true, automatically create a temporary stash entry before the operation begins, and apply it after the operation ends. This means that you can run merge on a dirty worktree. However, use with care: the final stash application after a successful merge might result in non-trivial conflicts. This option can be overridden by the --no-autostash and --autostash options of git-merge[1]. Defaults to false.

Controls which merge tool is used by git-mergetool[1]. The list below shows the valid built-in values. Any other value is treated as a custom merge tool and requires that a corresponding mergetool.<tool>.cmd variable is defined.

Controls which merge tool is used by git-mergetool[1] when the -g/--gui flag is specified. The list below shows the valid built-in values. Any other value is treated as a custom merge tool and requires that a corresponding mergetool.<guitool>.cmd variable is defined.

Controls the amount of output shown by the recursive merge strategy. Level 0 outputs nothing except a final error message if conflicts were detected. Level 1 outputs only conflicts, 2 outputs conflicts and file changes. Level 5 and above outputs debugging information. The default is level 2. Can be overridden by the GIT_MERGE_VERBOSITY environment variable.

Defines a human-readable name for a custom low-level merge driver. See gitattributes[5] for details.

Defines the command that implements a custom low-level merge driver. See gitattributes[5] for details.

Names a low-level merge driver to be used when performing an internal merge between common ancestors. See gitattributes[5] for details.

Override the path for the given tool. This is useful in case your tool is not in the PATH.

Specify the command to invoke the specified merge tool. The specified command is evaluated in shell with the following variables available: BASE is the name of a temporary file containing the common base of the files to be merged, if available; LOCAL is the name of a temporary file containing the contents of the file on the current branch; REMOTE is the name of a temporary file containing the contents of the file from the branch being merged; MERGED contains the name of the file to which the merge tool should write the results of a successful merge.

Allows the user to override the global mergetool.hideResolved value for a specific tool. See mergetool.hideResolved for the full description.

For a custom merge command, specify whether the exit code of the merge command can be used to determine whether the merge was successful. If this is not set to true then the merge target file timestamp is checked, and the merge is assumed to have been successful if the file has been updated; otherwise, the user is prompted to indicate the success of the merge.

Older versions of meld do not support the --output option. Git will attempt to detect whether meld supports --output by inspecting the output of meld --help. Configuring mergetool.meld.hasOutput will make Git skip these checks and use the configured value instead. Setting mergetool.meld.hasOutput to true tells Git to unconditionally use the --output option, and false avoids using --output.

When the --auto-merge is given, meld will merge all non-conflicting parts automatically, highlight the conflicting parts, and wait for user decision. Setting mergetool.meld.useAutoMerge to true tells Git to unconditionally use the --auto-merge option with meld. Setting this value to auto makes git detect whether --auto-merge is supported and will only use --auto-merge when available. A value of false avoids using --auto-merge altogether, and is the default value.

Configure the split window layout for vimdiff’s <variant>, which is any of vimdiff, nvimdiff, gvimdiff. Upon launching git mergetool with --tool=<variant> (or without --tool if merge.tool is configured as <variant>), Git will consult mergetool.<variant>.layout to determine the tool’s layout. If the variant-specific configuration is not available, vimdiff's is used as fallback. If that too is not available, a default layout with 4 windows will be used. To configure the layout, see the BACKEND SPECIFIC HINTS section in git-mergetool[1].

During a merge, Git will automatically resolve as many conflicts as possible and write the MERGED file containing conflict markers around any conflicts that it cannot resolve; LOCAL and REMOTE normally represent the versions of the file from before Git’s conflict resolution. This flag causes LOCAL and REMOTE to be overwritten so that only the unresolved conflicts are presented to the merge tool. Can be configured per-tool via the mergetool.<tool>.hideResolved configuration variable. Defaults to false.

After performing a merge, the original file with conflict markers can be saved as a file with a .orig extension. If this variable is set to false then this file is not preserved. Defaults to true (i.e. keep the backup files).

When invoking a custom merge tool, Git uses a set of temporary files to pass to the tool. If the tool returns an error and this variable is set to true, then these temporary files will be preserved; otherwise, they will be removed after the tool has exited. Defaults to false.

Git writes temporary BASE, LOCAL, and REMOTE versions of conflicting files in the worktree by default. Git will attempt to use a temporary directory for these files when set true. Defaults to false.

Prompt before each invocation of the merge resolution program.

Set true to use the merge.guitool by default (equivalent to specifying the --gui argument), or auto to select merge.guitool or merge.tool depending on the presence of a DISPLAY environment variable value. The default is false, where the --gui argument must be provided explicitly for the merge.guitool to be used.

Which merge strategy to choose by default when resolving notes conflicts. Must be one of manual, ours, theirs, union, or cat_sort_uniq. Defaults to manual. See the "NOTES MERGE STRATEGIES" section of git-notes[1] for more information on each strategy.

Which merge strategy to choose when doing a notes merge into refs/notes/<name>. This overrides the more general "notes.mergeStrategy". See the "NOTES MERGE STRATEGIES" section in git-notes[1] for more information on the available strategies.

Which ref (or refs, if a glob or specified more than once), in addition to the default set by core.notesRef or GIT_NOTES_REF, to read notes from when showing commit messages with the git log family of commands.

When rewriting commits with <command> (currently amend or rebase), if this variable is false, git will not copy notes from the original to the rewritten commit. Defaults to true. See also "notes.rewriteRef" below.

When copying notes during a rewrite (see the "notes.rewrite.<command>" option), determines what to do if the target commit already has a note. Must be one of overwrite, concatenate, cat_sort_uniq, or ignore. Defaults to concatenate.

When copying notes during a rewrite, specifies the (fully qualified) ref whose notes should be copied. May be a glob, in which case notes in all matching refs will be copied. You may also specify this configuration several times.

The size of the window used by git-pack-objects[1] when no window size is given on the command line. Defaults to 10.

The maximum delta depth used by git-pack-objects[1] when no maximum depth is given on the command line. Defaults to 50. Maximum value is 4095.

The maximum size of memory that is consumed by each thread in git-pack-objects[1] for pack window memory when no limit is given on the command line. The value can be suffixed with "k", "m", or "g". When left unconfigured (or set explicitly to 0), there will be no limit.

An integer -1..9, indicating the compression level for objects in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to -1, the zlib default, which is "a default compromise between speed and compression (currently equivalent to level 6)."

When true or "single", and when reachability bitmaps are enabled, pack-objects will try to send parts of the bitmapped packfile verbatim. When "multi", and when a multi-pack reachability bitmap is available, pack-objects will try to send parts of all packs in the MIDX.

An extended regular expression configuring a set of delta islands. See "DELTA ISLANDS" in git-pack-objects[1] for details.

Specify an island name which gets to have its objects be packed first. This creates a kind of pseudo-pack at the front of one pack, so that the objects from the specified island are hopefully faster to copy into any pack that should be served to a user requesting these objects. In practice this means that the island specified should likely correspond to what is the most commonly cloned in the repo. See also "DELTA ISLANDS" in git-pack-objects[1].

The maximum memory in bytes used for caching deltas in git-pack-objects[1] before writing them out to a pack. This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Repacking large repositories on machines which are tight with memory might be badly impacted by this though, especially if this cache pushes the system into swapping. A value of 0 means no limit. The smallest size of 1 byte may be used to virtually disable this cache. Defaults to 256 MiB.

The maximum size of a delta, that is cached in git-pack-objects[1]. This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Defaults to 1000. Maximum value is 65535.

Specifies the number of threads to spawn when searching for best delta matches. This requires that git-pack-objects[1] be compiled with pthreads otherwise this option is ignored with a warning. This is meant to reduce packing time on multiprocessor machines. The required amount of memory for the delta search window is however multiplied by the number of threads. Specifying 0 will cause Git to auto-detect the number of CPUs and set the number of threads accordingly.

Specify the default pack index version. Valid values are 1 for legacy pack index used by Git versions prior to 1.5.2, and 2 for the new pack index with capabilities for packs larger than 4 GB as well as proper protection against the repacking of corrupted packs. Version 2 is the default. Note that version 2 is enforced and this config option is ignored whenever the corresponding pack is larger than 2 GB.

The maximum size of a pack. This setting only affects packing to a file when repacking, i.e. the git:// protocol is unaffected. It can be overridden by the --max-pack-size option of git-repack[1]. Reaching this limit results in the creation of multiple packfiles.

When true, git will use pack bitmaps (if available) when packing to stdout (e.g., during the server side of a fetch). Defaults to true. You should not generally need to turn this off unless you are debugging pack bitmaps.

When true, Git will use an experimental algorithm for computing reachability queries with bitmaps. Instead of building up complete bitmaps for all of the negated tips and then OR-ing them together, consider negated tips with existing bitmaps as additive (i.e. OR-ing them into the result if they exist, ignoring them otherwise), and build up a bitmap at the boundary instead.

When true, git will default to using the --sparse option in git pack-objects when the --revs option is present. This algorithm only walks trees that appear in paths that introduce new objects. This can have significant performance benefits when computing a pack to send a small change. However, it is possible that extra objects are added to the pack-file if the included commits contain certain types of direct renames. Default is true.

When selecting which commits will receive bitmaps, prefer a commit at the tip of any reference that is a suffix of any value of this configuration over any other commits in the "selection window".

This is a deprecated synonym for repack.writeBitmaps.

When true, git will include a "hash cache" section in the bitmap index (if one is written). This cache can be used to feed git’s delta heuristics, potentially leading to better deltas between bitmapped and non-bitmapped objects (e.g., when serving a fetch between an older, bitmapped pack and objects that have been pushed since the last gc). The downside is that it consumes 4 bytes per object of disk space. Defaults to true.

When true, Git will include a "lookup table" section in the bitmap index (if one is written). This table is used to defer loading individual bitmaps as late as possible. This can be beneficial in repositories that have relatively large bitmap indexes. Defaults to false.

When true, git will read any .rev file(s) that may be available (see: gitformat-pack[5]). When false, the reverse index will be generated from scratch and stored in memory. Defaults to true.

When true, git will write a corresponding .rev file (see: gitformat-pack[5]) for each new packfile that it writes in all places except for git-fast-import[1] and in the bulk checkin mechanism. Defaults to true.

If the value is boolean, turns on or off pagination of the output of a particular Git subcommand when writing to a tty. Otherwise, turns on pagination for the subcommand using the pager specified by the value of pager.<cmd>. If --paginate or --no-pager is specified on the command line, it takes precedence over this option. To disable pagination for all commands, set core.pager or GIT_PAGER to cat.

Alias for a --pretty= format string, as specified in git-log[1]. Any aliases defined here can be used just as the built-in pretty formats could. For example, running git config pretty.changelog "format:* %H %s" would cause the invocation git log --pretty=changelog to be equivalent to running git log "--pretty=format:* %H %s". Note that an alias with the same name as a built-in format will be silently ignored.

If set to "true" assume --quiet when fetching additional objects for a partial clone.

If set, provide a user defined default policy for all protocols which don’t explicitly have a policy (protocol.<name>.allow). By default, if unset, known-safe protocols (http, https, git, ssh) have a default policy of always, known-dangerous protocols (ext) have a default policy of never, and all other protocols (including file) have a default policy of user. Supported policies:

Set a policy to be used by protocol <name> with clone/fetch/push commands. See protocol.allow above for the available policies.

If set, clients will attempt to communicate with a server using the specified protocol version. If the server does not support it, communication falls back to version 0. If unset, the default is 2. Supported versions:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded. When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line). When set to only, only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line). This setting overrides merge.ff when pulling.

When true, rebase branches on top of the fetched branch, instead of merging the default branch from the default remote when "git pull" is run. See "branch.<name>.rebase" for setting this on a per-branch basis.

The default merge strategy to use when pulling multiple branches at once.

The default merge strategy to use when pulling a single branch.

If set to "true" assume --set-upstream on default push when no upstream tracking exists for the current branch; this option takes effect with push.default options simple, upstream, and current. It is useful if by default you want new branches to be pushed to the default remote (like the behavior of push.default=current) and you also want the upstream tracking to be set. Workflows most likely to benefit from this option are simple central workflows where all branches are expected to have the same name on the remote.

Defines the action git push should take if no refspec is given (whether from the command-line, config, or elsewhere). Different values are well-suited for specific workflows; for instance, in a purely central workflow (i.e. the fetch source is equal to the push destination), upstream is probably what you want. Possible values are:

If set to true, enable --follow-tags option by default. You may override this configuration at time of push by specifying --no-follow-tags.

May be set to a boolean value, or the string if-asked. A true value causes all pushes to be GPG signed, as if --signed is passed to git-push[1]. The string if-asked causes pushes to be signed if the server supports it, as if --signed=if-asked is passed to git push. A false value may override a value from a lower-priority config file. An explicit command-line flag always overrides this config option.

When no --push-option=<option> argument is given from the command line, git push behaves as if each <value> of this variable is given as --push-option=<value>.

Example:

/etc/gitconfig
  push.pushoption = a
  push.pushoption = b

~/.gitconfig
  push.pushoption = c

repo/.git/config
  push.pushoption =
  push.pushoption = b

This will result in only b (a and c are cleared).

May be "check", "on-demand", "only", or "no", with the same behavior as that of "push --recurse-submodules". If not set, no is used by default, unless submodule.recurse is set (in which case a true value means on-demand).

If set to "true", it is equivalent to specifying --force-if-includes as an option to git-push[1] in the command line. Adding --no-force-if-includes at the time of push overrides this configuration setting.

If set to "true", attempt to reduce the size of the packfile sent by rounds of negotiation in which the client and the server attempt to find commits in common. If "false", Git will rely solely on the server’s ref advertisement to find commits in common.

If set to "false", disable use of bitmaps for "git push" even if pack.useBitmaps is "true", without preventing other git operations from using bitmaps. Default is true.

Default backend to use for rebasing. Possible choices are apply or merge. In the future, if the merge backend gains all remaining capabilities of the apply backend, this setting may become unused.

Whether to show a diffstat of what changed upstream since the last rebase. False by default.

If set to true, enable the --autosquash option of git-rebase[1] by default for interactive mode. This can be overridden with the --no-autosquash option.

When set to true, automatically create a temporary stash entry before the operation begins, and apply it after the operation ends. This means that you can run rebase on a dirty worktree. However, use with care: the final stash application after a successful rebase might result in non-trivial conflicts. This option can be overridden by the --no-autostash and --autostash options of git-rebase[1]. Defaults to false.

If set to true enable --update-refs option by default.

If set to "warn", git rebase -i will print a warning if some commits are removed (e.g. a line was deleted), however the rebase will still proceed. If set to "error", it will print the previous warning and stop the rebase, git rebase --edit-todo can then be used to correct the error. If set to "ignore", no checking is done. To drop a commit without warning or error, use the drop command in the todo list. Defaults to "ignore".

A format string, as specified in git-log[1], to be used for the todo list during an interactive rebase. The format will automatically have the commit hash prepended to the format.

If set to true, git rebase will use abbreviated command names in the todo list resulting in something like this:

	p deadbee The oneline of the commit
	p fa1afe1 The oneline of the next commit
	...

	pick deadbee The oneline of the commit
	pick fa1afe1 The oneline of the next commit
	...

Automatically reschedule exec commands that failed. This only makes sense in interactive mode (or when an --exec option was provided). This is the same as specifying the --reschedule-failed-exec option.

If set to false set --no-fork-point option by default.

Whether and how to set the --rebase-merges option by default. Can be rebase-cousins, no-rebase-cousins, or a boolean. Setting to true or to no-rebase-cousins is equivalent to --rebase-merges=no-rebase-cousins, setting to rebase-cousins is equivalent to --rebase-merges=rebase-cousins, and setting to false is equivalent to --no-rebase-merges. Passing --rebase-merges on the command line, with or without an argument, overrides any rebase.rebaseMerges configuration.

When generating label names from commit subjects, truncate the names to this length. By default, the names are truncated to a little less than NAME_MAX (to allow e.g. .lock files to be written for the corresponding loose refs).

By default, git-receive-pack will advertise the atomic push capability to its clients. If you don’t want to advertise this capability, set this variable to false.

When set to true, git-receive-pack will advertise the push options capability to its clients. False by default.

By default, git-receive-pack will run "git maintenance run --auto" after receiving data from git-push and updating refs. You can stop it by setting this variable to false.

By setting this variable to a string, git receive-pack will accept a git push --signed and verify it by using a "nonce" protected by HMAC using this string as a secret key.

When a git push --signed sends a push certificate with a "nonce" that was issued by a receive-pack serving the same repository within this many seconds, export the "nonce" found in the certificate to GIT_PUSH_CERT_NONCE to the hooks (instead of what the receive-pack asked the sending side to include). This may allow writing checks in pre-receive and post-receive a bit easier. Instead of checking GIT_PUSH_CERT_NONCE_SLOP environment variable that records by how many seconds the nonce is stale to decide if they want to accept the certificate, they only can check GIT_PUSH_CERT_NONCE_STATUS is OK.

If it is set to true, git-receive-pack will check all received objects. See transfer.fsckObjects for what’s checked. Defaults to false. If not set, the value of transfer.fsckObjects is used instead.

Acts like fsck.<msg-id>, but is used by git-receive-pack[1] instead of git-fsck[1]. See the fsck.<msg-id> documentation for details.

Acts like fsck.skipList, but is used by git-receive-pack[1] instead of git-fsck[1]. See the fsck.skipList documentation for details.

After receiving the pack from the client, receive-pack may produce no output (if --quiet was specified) while processing the pack, causing some networks to drop the TCP connection. With this option set, if receive-pack does not transmit any data in this phase for receive.keepAlive seconds, it will send a short keepalive packet. The default is 5 seconds; set to 0 to disable keepalives entirely.

If the number of objects received in a push is below this limit then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead.

If the size of the incoming pack stream is larger than this limit, then git-receive-pack will error out, instead of accepting the pack file. If not set or set to 0, then the size is unlimited.

If set to true, git-receive-pack will deny a ref update that deletes the ref. Use this to prevent such a ref deletion via a push.

If set to true, git-receive-pack will deny a ref update that deletes the currently checked out branch of a non-bare repository.

If set to true or "refuse", git-receive-pack will deny a ref update to the currently checked out branch of a non-bare repository. Such a push is potentially dangerous because it brings the HEAD out of sync with the index and working tree. If set to "warn", print a warning of such a push to stderr, but allow the push to proceed. If set to false or "ignore", allow such pushes with no message. Defaults to "refuse".

If set to true, git-receive-pack will deny a ref update which is not a fast-forward. Use this to prevent such an update via a push, even if that push is forced. This configuration variable is set when initializing a shared repository.

This variable is the same as transfer.hideRefs, but applies only to receive-pack (and so affects pushes, but not fetches). An attempt to update or delete a hidden ref by git push is rejected.

This is a multi-valued variable that defines reference prefixes to match the commands in receive-pack. Commands matching the prefixes will be executed by an external hook "proc-receive", instead of the internal execute_commands function. If this variable is not defined, the "proc-receive" hook will never be used, and all commands will be executed by the internal execute_commands function.

git config --system --add receive.procReceiveRefs ad:refs/heads
git config --system --add receive.procReceiveRefs !:refs/heads

If set to true, git-receive-pack will run git-update-server-info after receiving data from git-push and updating refs.

If set to true, .git/shallow can be updated when new refs require new shallow roots. Otherwise those refs are rejected.

The size in bytes used by the reftable backend when writing blocks. The block size is determined by the writer, and does not have to be a power of 2. The block size must be larger than the longest reference name or log entry used in the repository, as references cannot span blocks.

The interval at which to create restart points. The reftable backend determines the restart points at file creation. Every 16 may be more suitable for smaller block sizes (4k or 8k), every 64 for larger block sizes (64k).

Whether the reftable backend shall write object blocks. Object blocks are a reverse mapping of object ID to the references pointing to them.

Whenever the reftable backend appends a new table to the stack, it performs auto compaction to ensure that there is only a handful of tables. The backend does this by ensuring that tables form a geometric sequence regarding the respective sizes of each table.

Whenever the reftable backend appends a new table to the stack, it has to lock the central "tables.list" file before updating it. This config controls how long the process will wait to acquire the lock in case another process has already acquired it. Value 0 means not to retry at all; -1 means to try indefinitely. Default is 100 (i.e., retry for 100ms).

The remote to push to by default. Overrides branch.<name>.remote for all branches, and is overridden by branch.<name>.pushRemote for specific branches.

The URL of a remote repository. See git-fetch[1] or git-push[1]. A configured remote can have multiple URLs; in this case the first is used for fetching, and all are used for pushing (assuming no remote.<name>.pushurl is defined). Setting this key to the empty string clears the list of urls, allowing you to override earlier config.

The push URL of a remote repository. See git-push[1]. If a pushurl option is present in a configured remote, it is used for pushing instead of remote.<name>.url. A configured remote can have multiple push URLs; in this case a push goes to all of them. Setting this key to the empty string clears the list of urls, allowing you to override earlier config.

For remotes that require curl (http, https and ftp), the URL to the proxy to use for that remote. Set to the empty string to disable proxying for that remote.

For remotes that require curl (http, https and ftp), the method to use for authenticating against the proxy in use (probably set in remote.<name>.proxy). See http.proxyAuthMethod.

The default set of "refspec" for git-fetch[1]. See git-fetch[1].

The default set of "refspec" for git-push[1]. See git-push[1].

If true, pushing to this remote will automatically behave as if the --mirror option was given on the command line.

A deprecated synonym to remote.<name>.skipFetchAll (if both are set in the configuration files with different values, the value of the last occurrence will be used).

If true, this remote will be skipped when updating using git-fetch[1], the update subcommand of git-remote[1], and ignored by the prefetch task of git maintenance.

The default program to execute on the remote side when pushing. See option --receive-pack of git-push[1].

The default program to execute on the remote side when fetching. See option --upload-pack of git-fetch-pack[1].

Setting this value to --no-tags disables automatic tag following when fetching from remote <name>. Setting it to --tags will fetch every tag from remote <name>, even if they are not reachable from remote branch heads. Passing these flags directly to git-fetch[1] can override this setting. See options --tags and --no-tags of git-fetch[1].

Setting this to a value <vcs> will cause Git to interact with the remote with the git-remote-<vcs> helper.

When set to true, fetching from this remote by default will also remove any remote-tracking references that no longer exist on the remote (as if the --prune option was given on the command line). Overrides fetch.prune settings, if any.

When set to true, fetching from this remote by default will also remove any local tags that no longer exist on the remote if pruning is activated in general via remote.<name>.prune, fetch.prune or --prune. Overrides fetch.pruneTags settings, if any.

When set to true, this remote will be used to fetch promisor objects.

The filter that will be applied when fetching from this promisor remote. Changing or clearing this value will only affect fetches for new commits. To fetch associated objects for commits already present in the local object database, use the --refetch option of git-fetch[1].

The list of remotes which are fetched by "git remote update <group>". See git-remote[1].

By default, git-repack[1] creates packs that use delta-base offset. If you need to share your repository with Git older than version 1.4.4, either directly or via a dumb protocol such as http, then you need to set this option to "false" and repack. Access from old Git versions over the native protocol are unaffected by this option.

If set to true, makes git repack act as if --pack-kept-objects was passed. See git-repack[1] for details. Defaults to false normally, but true if a bitmap index is being written (either via --write-bitmap-index or repack.writeBitmaps).

If set to true, makes git repack act as if --delta-islands was passed. Defaults to false.

When true, git will write a bitmap index when packing all objects to disk (e.g., when git repack -a is run). This index can speed up the "counting objects" phase of subsequent packs created for clones and fetches, at the cost of some disk space and extra time spent on the initial repack. This has no effect if multiple packfiles are created. Defaults to true on bare repos, false otherwise.

If set to false, git-repack[1] will not run git-update-server-info[1]. Defaults to true. Can be overridden when true by the -n option of git-repack[1].

Parameters used by git-pack-objects[1] when generating a cruft pack and the respective parameters are not given over the command line. See similarly named pack.* configuration variables for defaults and meaning.

When set to true, git-rerere updates the index with the resulting contents after it cleanly resolves conflicts using previously recorded resolutions. Defaults to false.

Activate recording of resolved conflicts, so that identical conflict hunks can be resolved automatically, should they be encountered again. By default, git-rerere[1] is enabled if there is an rr-cache directory under the $GIT_DIR, e.g. if "rerere" was previously used in the repository.

Setting this variable to true makes git revert behave as if the --reference option is given.

Specifies which bare repositories Git will work with. The currently supported values are:

These config entries specify Git-tracked directories that are considered safe even if they are owned by someone other than the current user. By default, Git will refuse to even parse a Git config of a repository owned by someone else, let alone run its hooks, and this config setting allows users to specify exceptions, e.g. for intentionally shared repositories (see the --shared option in git-init[1]).

A configuration identity. When given, causes values in the sendemail.<identity> subsection to take precedence over values in the sendemail section. The default identity is the value of sendemail.identity.

See git-send-email[1] for description. Note that this setting is not subject to the identity mechanism.

Path to ca-certificates (either a directory or a single file). Set it to an empty string to disable certificate verification.

Identity-specific versions of the sendemail.* parameters found below, taking precedence over those when this identity is selected, through either the command-line or sendemail.identity.

If true (default), a single editor instance will be spawned to edit files you have to edit (patches when --annotate is used, and the summary when --compose is used). If false, files will be edited one after the other, spawning a new editor each time.

Sets the default for whether to confirm before sending. Must be one of always, never, cc, compose, or auto. See --confirm in the git-send-email[1] documentation for the meaning of these values.

If true, makes git-send-email[1] assume --mailmap, otherwise assume --no-mailmap. False by default.

The location of a git-send-email[1] specific augmenting mailmap file. The default mailmap and mailmap.file are loaded first. Thus, entries in this file take precedence over entries in the default mailmap locations. See gitmailmap[5].
