to the changeset to be committed next to the current
project: the current project is termed the "superproject".

-This requires two arguments: <repository> and <path>.
+This requires at least one argument: <repository>. The optional
+argument <path> is the relative location for the cloned submodule
+to exist in the superproject. If <path> is not given, the
+"humanish" part of the source repository is used ("repo" for
+"/path/to/repo.git" and "foo" for "host.xz:foo/.git").
+
<repository> is the URL of the new submodule's origin repository.
This may be either an absolute URL, or (if it begins with ./
status::
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
+ submodule path and the output of 'git describe' for the
SHA-1. Each SHA-1 will be prefixed with `-` if the submodule is not
initialized and `+` if the currently checked out submodule commit
does not match the SHA-1 found in the index of the containing
- repository. This command is the default command for 'git-submodule'.
+ repository. This command is the default command for 'git submodule'.
++
+If '--recursive' is specified, this command will recurse into nested
+submodules, and show their status as well.
init::
Initialize the submodules, i.e. register each submodule name
The key used in .git/config is `submodule.$name.url`.
This command does not alter existing information in .git/config.
You can then customize the submodule clone URLs in .git/config
- for your local setup and proceed to 'git submodule update';
- you can also just use 'git submodule update --init' without
+ for your local setup and proceed to `git submodule update`;
+ you can also just use `git submodule update --init` without
the explicit 'init' step if you do not intend to customize
any submodule locations.
update::
Update the registered submodules, i.e. clone missing submodules and
checkout the commit specified in the index of the containing repository.
- This will make the submodules HEAD be detached.
+ This will make the submodules HEAD be detached unless '--rebase' or
+ '--merge' is specified or the key `submodule.$name.update` is set to
+ `rebase` or `merge`.
+
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 --init option.
++
+If '--recursive' is specified, this command will recurse into the
+registered submodules, and update any nested submodules within.
summary::
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.
+ index or working tree (switched by --cached) are shown. If the option
+ --files is 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 --cached option or to provide an
+ explicit commit).
foreach::
Evaluates an arbitrary shell command in each checked out submodule.
- The command has access to the variables $path and $sha1:
+ The command has access to the variables $name, $path and $sha1:
+ $name is the name of the relevant submodule section in .gitmodules,
$path is the name of the submodule directory relative to the
superproject, and $sha1 is the commit as recorded in 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 --recursive is 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, "git submodule foreach 'echo $path `git rev-parse HEAD`' will
-show the path and currently checked out commit for each submodule.
+As an example, +git submodule foreach \'echo $path {backtick}git
+rev-parse HEAD{backtick}'+ will show the path and currently checked out
+commit for each submodule.
sync::
Synchronizes submodules' remote URL configuration setting
commands typically use the commit found in the submodule HEAD, but
with this option, the commit stored in the index is used instead.
+--files::
+ This option is only valid for the summary command. This command
+ compares the commit in the index with that in the submodule HEAD
+ when this option is used.
+
-n::
--summary-limit::
This option is only valid for the summary command.
This option is only valid for the update command.
Don't fetch new objects from the remote site.
+--merge::
+ This option is only valid for the update command.
+ Merge the commit recorded in the superproject into the current branch
+ of the submodule. If this option is given, the submodule's HEAD will
+ not be detached. If a merge failure prevents this process, you will
+ have to resolve the resulting conflicts within the submodule with the
+ usual conflict resolution tools.
+ If the key `submodule.$name.update` is set to `merge`, this option is
+ implicit.
+
+--rebase::
+ 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 linkgit:git-rebase[1].
+ If the key `submodule.$name.update` is set to `rebase`, this option is
+ implicit.
+
+--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 linkgit:git-clone[1] command.
++
+*NOTE*: Do *not* use this option unless you have read the note
+for linkgit:git-clone[1]'s --reference and --shared options carefully.
+
+--recursive::
+ This option is only valid for foreach, update and status 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).
+
<path>...::
Paths to submodule(s). When specified this will restrict the command
to only operate on the submodules found at the specified paths.
