git-submodule(1)
================

NAME
----
git-submodule - Initialize, update or inspect submodules


SYNOPSIS
--------
[verse]
'git-submodule' [--quiet] add [-b branch] [--] <repository> [<path>]
'git-submodule' [--quiet] status [--cached] [--] [<path>...]
'git-submodule' [--quiet] [init|update] [--] [<path>...]
'git-submodule' [--quiet] summary [--summary-limit <n>] [commit] [--] [<path>...]


COMMANDS
--------
add::
	Add the given repository as a submodule at the given path
	to the changeset to be committed next.  If path is a valid
	repository within the project, it is added as is. Otherwise,
	repository is cloned at the specified path. path is added to the
	changeset and registered in .gitmodules.   If no path is
	specified, the path is deduced from the repository specification.
	If the repository url begins with ./ or ../, it is stored as
	given but resolved as a relative path from the main project's
	url when cloning.

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 linkgit:git-describe[1] 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.

init::
	Initialize the submodules, i.e. register in .git/config each submodule
	name and url found in .gitmodules. The key used in .git/config is
	`submodule.$name.url`. This command does not alter existing information
	in .git/config.

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.

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.

OPTIONS
-------
-q, --quiet::
	Only print error messages.

-b, --branch::
	Branch of repository to add as submodule.

--cached::
	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.

-n, --summary-limit::
	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.

<path>::
	Path to submodule(s). When specified this will restrict the command
	to only operate on the submodules found at the specified paths.

FILES
-----
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 linkgit:gitmodules[5]
for details.
