-In the first form, source must exist and be either a file,
-symlink or directory, dest must not exist. It renames source to dest.
-In the second form, the last argument has to be an existing
-directory; the given sources will be moved into this directory.
-
-Updates the git cache to reflect the change.
-Use "git commit" to make the change permanently.
-
-Options:
- -f Force renaming/moving, even if target exists
- -k Continue on error by skipping
- not-existing or not revision-controlled source
- -n Do nothing; show what would happen
