16 $0 [-f] [-n] <source> <dest>
17 $0 [-f] [-k] [-n] <source> ... <dest directory>
19 In the first form, source must exist and be either a file,
20 symlink or directory, dest must not exist. It renames source to dest.
21 In the second form, the last argument has to be an existing
22 directory; the given sources will be moved into this directory.
24 Updates the git cache to reflect the change.
25 Use "git commit" to make the change permanently.
28 -f Force renaming/moving, even if target exists
29 -k Continue on error by skipping
30 not-existing or not revision-controlled source
31 -n Do nothing; show what would happen
