  18COMMANDS
  19--------
  20add::
  21        Add the given repository as a submodule at the given path
  22        to the changeset to be committed next.  If path is a valid
  23        repository within the project, it is added as is. Otherwise,
  24        repository is cloned at the specified path. path is added to the
  25        changeset and registered in .gitmodules.   If no path is
  26        specified, the path is deduced from the repository specification.
  27        If the repository url begins with ./ or ../, it is stored as
  28        given but resolved as a relative path from the main project's
  29        url when cloning.
  30
  31status::
  32        Show the status of the submodules. This will print the SHA-1 of the
  33        currently checked out commit for each submodule, along with the
  34        submodule path and the output of linkgit:git-describe[1] for the
  35        SHA-1. Each SHA-1 will be prefixed with `-` if the submodule is not
  36        initialized and `+` if the currently checked out submodule commit
  37        does not match the SHA-1 found in the index of the containing
  38        repository. This command is the default command for git-submodule.
  39
  40init::
  41        Initialize the submodules, i.e. register in .git/config each submodule
  42        name and url found in .gitmodules. The key used in .git/config is
  43        `submodule.$name.url`. This command does not alter existing information
  44        in .git/config.
  45
  46update::
  47        Update the registered submodules, i.e. clone missing submodules and
  48        checkout the commit specified in the index of the containing repository.
  49        This will make the submodules HEAD be detached.
  50
  51summary::
  52        Show commit summary between the given commit (defaults to HEAD) and
  53        working tree/index. For a submodule in question, a series of commits
  54        in the submodule between the given super project commit and the
  55        index or working tree (switched by --cached) are shown.
  56
  57OPTIONS
  58-------
  59-q, --quiet::
  60        Only print error messages.
  61
  62-b, --branch::
  63        Branch of repository to add as submodule.
  64
  65--cached::
  66        This option is only valid for status and summary commands.  These
  67        commands typically use the commit found in the submodule HEAD, but
  68        with this option, the commit stored in the index is used instead.
  69
  70-n, --summary-limit::
  71        This option is only valid for the summary command.
  72        Limit the summary size (number of commits shown in total).
  73        Giving 0 will disable the summary; a negative number means unlimted
  74        (the default). This limit only applies to modified submodules. The
  75        size is always limited to 1 for added/deleted/typechanged submodules.
  76
  77<path>::
  78        Path to submodule(s). When specified this will restrict the command
  79        to only operate on the submodules found at the specified paths.
  80
  81FILES
  82-----
  83When initializing submodules, a .gitmodules file in the top-level directory
  84of the containing repository is used to find the url of each submodule.
  85This file should be formatted in the same way as `$GIT_DIR/config`. The key
  86to each submodule url is "submodule.$name.url".  See linkgit:gitmodules[5]
  87for details.
