DESCRIPTION

You can query/set/replace/unset options with this command. The name is actually the section and the key separated by a dot, and the value will be escaped.

Multiple lines can be added to an option by using the --add option. If you want to update or unset an option which can occur on multiple lines, a POSIX regexp value_regex needs to be given. Only the existing values that match the regexp are updated or unset. If you want to handle the lines that do not match the regex, just prepend a single exclamation mark in front (see also EXAMPLES).

The type specifier can be either --int or --bool, to make git config ensure that the variable(s) are of the given type and convert the value to the canonical form (simple decimal number for int, a "true" or "false" string for bool), or --path, which does some path expansion (see --path below). If no type specifier is passed, no checks or transformations are performed on the value.

When reading, the values are read from the system, global and repository local configuration files by default, and options --system, --global, --local and --file <filename> can be used to tell the command to read from only that location (see FILES).

When writing, the new value is written to the repository local configuration file by default, and options --system, --global, --file <filename> can be used to tell the command to write to that location (you can say --local but that is the default).

This command will fail with non-zero status upon error. Some exit codes are:

  1. The config file is invalid (ret=3),

  2. can not write to the config file (ret=4),

  3. no section or name was provided (ret=2),

  4. the section or key is invalid (ret=1),

  5. you try to unset an option which does not exist (ret=5),

  6. you try to unset/set an option for which multiple lines match (ret=5), or

  7. you try to use an invalid regexp (ret=6).

On success, the command returns the exit code 0.

OPTIONS

--replace-all

Default behavior is to replace at most one line. This replaces all lines matching the key (and optionally the value_regex).

--add

Adds a new line to the option without altering any existing values. This is the same as providing ^$ as the value_regex in --replace-all.

--get

Get the value for a given key (optionally filtered by a regex matching the value). Returns error code 1 if the key was not found and the last value if multiple key values were found.

--get-all

Like get, but does not fail if the number of values for the key is not exactly one.

--get-regexp

Like --get-all, but interprets the name as a regular expression and writes out the key names. Regular expression matching is currently case-sensitive and done against a canonicalized version of the key in which section and variable names are lowercased, but subsection names are not.

--get-urlmatch name URL

When given a two-part name section.key, the value for section.<url>.key whose <url> part matches the best to the given URL is returned (if no such key exists, the value for section.key is used as a fallback). When given just the section as name, do so for all the keys in the section and list them.

--global

For writing options: write to global ~/.gitconfig file rather than the repository .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and the ~/.gitconfig file doesn’t.

For reading options: read only from global ~/.gitconfig and from $XDG_CONFIG_HOME/git/config rather than from all available files.

See also FILES.

--system

For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the repository .git/config.

For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than from all available files.

See also FILES.

--local

For writing options: write to the repository .git/config file. This is the default behavior.

For reading options: read only from the repository .git/config rather than from all available files.

See also FILES.

-f config-file
--file config-file

Use the given config file instead of the one specified by GIT_CONFIG.

--blob blob

Similar to --file but use the given blob instead of a file. E.g. you can use master:.gitmodules to read values from the file .gitmodules in the master branch. See "SPECIFYING REVISIONS" section in linkgit:gitrevisions[7] for a more complete list of ways to spell blob names.

--remove-section

Remove the given section from the configuration file.

--rename-section

Rename the given section to a new name.

--unset

Remove the line matching the key from config file.

--unset-all

Remove all lines matching the key from config file.

-l
--list

List all variables set in config file.

--bool

git config will ensure that the output is "true" or "false"

--int

git config will ensure that the output is a simple decimal number. An optional value suffix of k, m, or g in the config file will cause the value to be multiplied by 1024, 1048576, or 1073741824 prior to output.

--bool-or-int

git config will ensure that the output matches the format of either --bool or --int, as described above.

--path

git-config will expand leading ~ to the value of $HOME, and ~user to the home directory for the specified user. This option has no effect when setting the value (but you can use git config bla ~/ from the command line to let your shell do the expansion).

-z
--null

For all options that output values and/or keys, always end values with the null character (instead of a newline). Use newline instead as a delimiter between key and value. This allows for secure parsing of the output without getting confused e.g. by values that contain line breaks.

--get-colorbool name [stdout-is-tty]

Find the color setting for name (e.g. color.diff) and output "true" or "false". stdout-is-tty should be either "true" or "false", and is taken into account when configuration says "auto". If stdout-is-tty is missing, then checks the standard output of the command itself, and exits with status 0 if color is to be used, or exits with status 1 otherwise. When the color setting for name is undefined, the command uses color.ui as fallback.

--get-color name [default]

Find the color configured for name (e.g. color.diff.new) and output it as the ANSI color escape sequence to the standard output. The optional default parameter is used instead, if there is no color configured for name.

-e
--edit

Opens an editor to modify the specified config file; either --system, --global, or repository (default).

--[no-]includes

Respect include.* directives in config files when looking up values. Defaults to on.

FILES

If not set explicitly with --file, there are four files where git config will search for configuration options:

$(prefix)/etc/gitconfig

System-wide configuration file.

$XDG_CONFIG_HOME/git/config

Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty, $HOME/.config/git/config will be used. Any single-valued variable set in this file will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create this file if you sometimes use older versions of Git, as support for this file was added fairly recently.

~/.gitconfig

User-specific configuration file. Also called "global" configuration file.

$GIT_DIR/config

Repository specific configuration file.

If no further options are given, all reading options will read all of these files that are available. If the global or the system-wide configuration file are not available they will be ignored. If the repository configuration file is not available or readable, git config will exit with a non-zero error code. However, in neither case will an error message be issued.

The files are read in the order given above, with last value found taking precedence over values read earlier. When multiple values are taken then all values of a key from all files will be used.

All writing options will per default write to the repository specific configuration file. Note that this also affects options like --replace-all and --unset. git config will only ever change one file at a time.

You can override these rules either by command line options or by environment variables. The --global and the --system options will limit the file used to the global or system-wide file respectively. The GIT_CONFIG environment variable has a similar effect, but you can specify any filename you want.

ENVIRONMENT

GIT_CONFIG

Take the configuration from the given file instead of .git/config. Using the "--global" option forces this to ~/.gitconfig. Using the "--system" option forces this to $(prefix)/etc/gitconfig.

GIT_CONFIG_NOSYSTEM

Whether to skip reading settings from the system-wide $(prefix)/etc/gitconfig file. See linkgit:git[1] for details.

See also FILES.

EXAMPLES

Given a .git/config like this:

#
# This is the config file, and
# a '#' or ';' character indicates
# a comment
#
; core variables
[core]
    ; Don't trust file modes
    filemode = false
; Our diff algorithm
[diff]
    external = /usr/local/bin/diff-wrapper
    renames = true
; Proxy settings
[core]
    gitproxy=proxy-command for kernel.org
    gitproxy=default-proxy ; for all the rest
; HTTP
[http]
    sslVerify
[http "https://weak.example.com"]
    sslVerify = false
    cookieFile = /tmp/cookie.txt

you can set the filemode to true with

% git config core.filemode true

The hypothetical proxy command entries actually have a postfix to discern what URL they apply to. Here is how to change the entry for kernel.org to "ssh".

% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'

This makes sure that only the key/value pair for kernel.org is replaced.

To delete the entry for renames, do

% git config --unset diff.renames

If you want to delete an entry for a multivar (like core.gitproxy above), you have to provide a regex matching the value of exactly one line.

To query the value for a given key, do

% git config --get core.filemode

or

% git config core.filemode

or, to query a multivar:

% git config --get core.gitproxy "for kernel.org$"

If you want to know all the values for a multivar, do:

% git config --get-all core.gitproxy

If you like to live dangerously, you can replace all core.gitproxy by a new one with

% git config --replace-all core.gitproxy ssh

However, if you really only want to replace the line for the default proxy, i.e. the one without a "for …" postfix, do something like this:

% git config core.gitproxy ssh '! for '

To actually match only values with an exclamation mark, you have to

% git config section.key value '[!]'

To add a new proxy, without altering any of the existing ones, use

% git config --add core.gitproxy '"proxy-command" for example.com'

An example to use customized color from the configuration in your script:

#!/bin/sh
WS=$(git config --get-color color.diff.whitespace "blue reverse")
RESET=$(git config --get-color "" "reset")
echo "${WS}your whitespace color or blue reverse${RESET}"

For URLs in https://weak.example.com, http.sslVerify is set to false, while it is set to true for all others:

% git config --bool --get-urlmatch http.sslverify https://good.example.com
true
% git config --bool --get-urlmatch http.sslverify https://weak.example.com
false
% git config --get-urlmatch http https://weak.example.com
http.cookiefile /tmp/cookie.txt
http.sslverify false
