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 be prefixed with `-` if the submodule is not
- initialized and `+` if the currently checked out submodule commit
+ initialized, `+` 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 and `U` if the submodule has merge conflicts.
+ 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.
sync::
Synchronizes submodules' remote URL configuration setting
- to the value specified in .gitmodules. This is useful when
+ to the value specified in .gitmodules. It will only affect those
+ submodules which already have an 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.
+
-f::
--force::
- This option is only valid for the add command.
- Allow adding an otherwise ignored submodule path.
+ This option is only valid for add and update commands.
+ When running add, allow adding an otherwise ignored submodule path.
+ When running update, throw away local changes in submodules when
+ switching to a different commit.
--cached::
This option is only valid for status and summary commands. These
to each submodule url is "submodule.$name.url". See linkgit:gitmodules[5]
for details.
