+git-mv(1)
+=========
+
+NAME
+----
+git-mv - Move or rename a file, a directory, or a symlink
+
+
+SYNOPSIS
+--------
+[verse]
+'git mv' [<options>] <source>... <destination>
+
+DESCRIPTION
+-----------
+Move or rename a file, directory, or symlink.
+
+ git mv [-v] [-f] [-n] [-k] <source> <destination>
+ git mv [-v] [-f] [-n] [-k] <source> ... <destination-directory>
+
+In the first form, it renames <source>, which must exist and be either
+a file, symlink or directory, to <destination>.
+In the second form, the last argument has to be an existing
+directory; the given sources will be moved into this directory.
+
+The index is updated after successful completion, but the change must still be
+committed.
+
+OPTIONS
+-------
+-f::
+--force::
+	Force renaming or moving of a file even if the <destination> exists.
+-k::
+	Skip move or rename actions which would lead to an error
+	condition. An error happens when a source is neither existing nor
+	controlled by Git, or when it would overwrite an existing
+	file unless `-f` is given.
+-n::
+--dry-run::
+	Do nothing; only show what would happen
+
+-v::
+--verbose::
+	Report the names of files as they are moved.
+
+SUBMODULES
+----------
+Moving a submodule using a gitfile (which means they were cloned
+with a Git version 1.7.8 or newer) will update the gitfile and
+core.worktree setting to make the submodule work in the new location.
+It also will attempt to update the submodule.<name>.path setting in
+the linkgit:gitmodules[5] file and stage that file (unless -n is used).
+
+BUGS
+----
+Each time a superproject update moves a populated submodule (e.g. when
+switching between commits before and after the move) a stale submodule
+checkout will remain in the old location and an empty directory will
+appear in the new location. To populate the submodule again in the new
+location the user will have to run "git submodule update"
+afterwards. Removing the old directory is only safe when it uses a
+gitfile, as otherwise the history of the submodule will be deleted
+too. Both steps will be obsolete when recursive submodule update has
+been implemented.
