- add [-b <branch>] [-f|--force] [--name <name>] [--reference <repository>] [--depth <depth>] [--] <repository> [<path>]
Add the given repository as a submodule at the given path to the changeset to be committed next to the current project: the current project is termed the "superproject".
<repository> is the URL of the new submodule’s origin repository. This may be either an absolute URL, or (if it begins with ./ or ../), the location relative to the superproject’s default remote repository (Please note that to specify a repository foo.git which is located right next to a superproject bar.git, you’ll have to use ../foo.git instead of ./foo.git - as one might expect when following the rules for relative URLs - because the evaluation of relative URLs in Git is identical to that of relative directories).
The default remote is the remote of the remote tracking branch of the current branch. If no such remote tracking branch exists or the HEAD is detached, "origin" is assumed to be the default remote. If the superproject doesn’t have a default remote configured the superproject is its own authoritative upstream and the current working directory is used instead.
The optional argument <path> is the relative location for the cloned submodule to exist in the superproject. If <path> is not given, the canonical part of the source repository is used ("repo" for "/path/to/repo.git" and "foo" for "host.xz:foo/.git"). If <path> exists and is already a valid Git repository, then it is staged for commit without cloning. The <path> is also used as the submodule’s logical name in its configuration entries unless
--nameis used to specify a logical name.
The given URL is recorded into
.gitmodulesfor use by subsequent users cloning the superproject. If the URL is given relative to the superproject’s repository, the presumption is the superproject and submodule repositories will be kept together in the same relative location, and only the superproject’s URL needs to be provided. git-submodule will correctly locate the submodule using the relative URL in
- status [--cached] [--recursive] [--] [<path>…]
Show the status of the submodules. This will print the SHA-1 of the currently checked out commit for each submodule, along with the submodule path and the output of git describe for the SHA-1. Each SHA-1 will possibly be prefixed with
-if the submodule is not initialized,
+if the currently checked out submodule commit does not match the SHA-1 found in the index of the containing repository and
Uif the submodule has merge conflicts.
--recursiveis specified, this command will recurse into nested submodules, and show their status as well.
- init [--] [<path>…]
Initialize the submodules recorded in the index (which were added and committed elsewhere) by setting
submodule.$name.urlin .git/config. It uses the same setting from
.gitmodulesas a template. If the URL is relative, it will be resolved using the default remote. If there is no default remote, the current repository will be assumed to be upstream.
Optional <path> arguments limit which submodules will be initialized. If no path is specified and submodule.active has been configured, submodules configured to be active will be initialized, otherwise all submodules are initialized.
When present, it will also copy the value of
submodule.$name.update. This command does not alter existing information in .git/config. You can then customize the submodule clone URLs in .git/config for your local setup and proceed to
git submodule update; you can also just use
git submodule update --initwithout the explicit init step if you do not intend to customize any submodule locations.
See the add subcommand for the definition of default remote.
- deinit [-f|--force] (--all|[--] <path>…)
Unregister the given submodules, i.e. remove the whole
submodule.$namesection from .git/config together with their work tree. Further calls to
git submodule update,
git submodule foreachand
git submodule syncwill skip any unregistered submodules until they are initialized again, so use this command if you don’t want to have a local checkout of the submodule in your working tree anymore.
When the command is run without pathspec, it errors out, instead of deinit-ing everything, to prevent mistakes.
--forceis specified, the submodule’s working tree will be removed even if it contains local modifications.
- update [--init] [--remote] [-N|--no-fetch] [--[no-]recommend-shallow] [-f|--force] [--checkout|--rebase|--merge] [--reference <repository>] [--depth <depth>] [--recursive] [--jobs <n>] [--] [<path>…]
Update the registered submodules to match what the superproject expects by cloning missing submodules and updating the working tree of the submodules. The "updating" can be done in several ways depending on command line options and the value of
submodule.<name>.updateconfiguration variable. The command line option takes precedence over the configuration variable. If neither is given, a checkout is performed. The update procedures supported both from the command line as well as through the
the commit recorded in the superproject will be checked out in the submodule on a detached HEAD.
--forceis specified, the submodule will be checked out (using
git checkout --force), even if the commit specified in the index of the containing repository already matches the commit checked out in the submodule.
the current branch of the submodule will be rebased onto the commit recorded in the superproject.
the commit recorded in the superproject will be merged into the current branch in the submodule.
The following update procedures are only available via the
If the submodule is not yet initialized, and you just want to use the setting as stored in
.gitmodules, you can automatically initialize the submodule with the
--recursiveis specified, this command will recurse into the registered submodules, and update any nested submodules within.
- summary [--cached|--files] [(-n|--summary-limit) <n>] [commit] [--] [<path>…]
Show commit summary between the given commit (defaults to HEAD) and working tree/index. For a submodule in question, a series of commits in the submodule between the given super project commit and the index or working tree (switched by
--cached) are shown. If the option
--filesis given, show the series of commits in the submodule between the index of the super project and the working tree of the submodule (this option doesn’t allow to use the
--cachedoption or to provide an explicit commit).
--submodule=logoption with git-diff will provide that information too.
- foreach [--recursive] <command>
Evaluates an arbitrary shell command in each checked out submodule. The command has access to the variables $name, $path, $sha1 and $toplevel: $name is the name of the relevant submodule section in
.gitmodules, $path is the name of the submodule directory relative to the superproject, $sha1 is the commit as recorded in the superproject, and $toplevel is the absolute path to the top-level of the superproject. Any submodules defined in the superproject but not checked out are ignored by this command. Unless given
--quiet, foreach prints the name of each submodule before evaluating the command. If
--recursiveis given, submodules are traversed recursively (i.e. the given shell command is evaluated in nested submodules as well). A non-zero return from the command in any submodule causes the processing to terminate. This can be overridden by adding || : to the end of the command.
As an example, the command below will show the path and currently checked out commit for each submodule:
git submodule foreach 'echo $path `git rev-parse HEAD`'
- sync [--recursive] [--] [<path>…]
Synchronizes submodules' remote URL configuration setting to the value specified in
.gitmodules. It will only affect those submodules which already have a URL entry in .git/config (that is the case when they are initialized or freshly added). This is useful when submodule URLs change upstream and you need to update your local repositories accordingly.
"git submodule sync" synchronizes all submodules while "git submodule sync -- A" synchronizes submodule "A" only.
--recursiveis specified, this command will recurse into the registered submodules, and sync any nested submodules within.
If a git directory of a submodule is inside the submodule, move the git directory of the submodule into its superprojects
$GIT_DIR/modulespath and then connect the git directory and its working directory by setting the
core.worktreeand adding a .git file pointing to the git directory embedded in the superprojects git directory.
A repository that was cloned independently and later added as a submodule or old setups have the submodules git directory inside the submodule instead of embedded into the superprojects git directory.
This command is recursive by default.
Only print error messages.
This option is only valid for the deinit command. Unregister all submodules in the working tree.
Branch of repository to add as submodule. The name of the branch is recorded as
update --remote. A special value of
.is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.
This option is only valid for add, deinit and update commands. When running add, allow adding an otherwise ignored submodule path. When running deinit the submodule working trees will be removed even if they contain local changes. When running update (only effective with the checkout procedure), throw away local changes in submodules when switching to a different commit; and always run a checkout operation in the submodule, even if the commit listed in the index of the containing repository matches the commit checked out in the submodule.
This option is only valid for status and summary commands. These commands typically use the commit found in the submodule HEAD, but with this option, the commit stored in the index is used instead.
This option is only valid for the summary command. This command compares the commit in the index with that in the submodule HEAD when this option is used.
This option is only valid for the summary command. Limit the summary size (number of commits shown in total). Giving 0 will disable the summary; a negative number means unlimited (the default). This limit only applies to modified submodules. The size is always limited to 1 for added/deleted/typechanged submodules.
This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch. The remote used is branch’s remote (
branch.<name>.remote), defaulting to
origin. The remote branch used defaults to
master, but the branch name may be overridden by setting the
submodule.<name>.branchoption in either
This works for any of the supported update procedures (
--rebase, etc.). The only change is the source of the target SHA-1. For example,
submodule update --remote --mergewill merge upstream submodule changes into the submodules, while
submodule update --mergewill merge superproject gitlink changes into the submodules.
In order to ensure a current tracking branch state,
update --remotefetches the submodule’s remote repository before calculating the SHA-1. If you don’t want to fetch, you should use
submodule update --remote --no-fetch.
Use this option to integrate changes from the upstream subproject with your submodule’s current HEAD. Alternatively, you can run
git pullfrom the submodule, which is equivalent except for the remote branch name:
update --remoteuses the default upstream repository and
git pulluses the submodule’s
submodule.<name>.branchif you want to distribute the default upstream branch with the superproject and
branch.<name>.mergeif you want a more native feel while working in the submodule itself.
This option is only valid for the update command. Don’t fetch new objects from the remote site.
This option is only valid for the update command. Checkout the commit recorded in the superproject on a detached HEAD in the submodule. This is the default behavior, the main use of this option is to override
submodule.$name.updatewhen set to a value other than
checkout. If the key
submodule.$name.updateis either not explicitly set or set to
checkout, this option is implicit.
This option is only valid for the update command. Merge the commit recorded in the superproject into the current branch of the submodule. If this option is given, the submodule’s HEAD will not be detached. If a merge failure prevents this process, you will have to resolve the resulting conflicts within the submodule with the usual conflict resolution tools. If the key
submodule.$name.updateis set to
merge, this option is implicit.
This option is only valid for the update command. Rebase the current branch onto the commit recorded in the superproject. If this option is given, the submodule’s HEAD will not be detached. If a merge failure prevents this process, you will have to resolve these failures with git-rebase. If the key
submodule.$name.updateis set to
rebase, this option is implicit.
This option is only valid for the update command. Initialize all submodules for which "git submodule init" has not been called so far before updating.
This option is only valid for the add command. It sets the submodule’s name to the given string instead of defaulting to its path. The name must be valid as a directory name and may not end with a /.
- --reference <repository>
This option is only valid for add and update commands. These commands sometimes need to clone a remote repository. In this case, this option will be passed to the git-clone command.
NOTE: Do not use this option unless you have read the note for git-clone's
This option is only valid for foreach, update, status and sync commands. Traverse submodules recursively. The operation is performed not only in the submodules of the current repo, but also in any nested submodules inside those submodules (and so on).
This option is valid for add and update commands. Create a shallow clone with a history truncated to the specified number of revisions. See git-clone
This option is only valid for the update command. The initial clone of a submodule will use the recommended
submodule.<name>.shallowas provided by the
.gitmodulesfile by default. To ignore the suggestions use
- -j <n>
- --jobs <n>
This option is only valid for the update command. Clone new submodules in parallel with as many jobs. Defaults to the
Paths to submodule(s). When specified this will restrict the command to only operate on the submodules found at the specified paths. (This argument is required with add).
When initializing submodules, a
.gitmodules file in the top-level directory
of the containing repository is used to find the url of each submodule.
This file should be formatted in the same way as
$GIT_DIR/config. The key
to each submodule url is "submodule.$name.url". See gitmodules
