svn unlock — Unlock working copy paths or URLs.
Unlock each TARGET.  If any
            TARGET is locked by
            another user or no valid lock token exists in the working
            copy, print a warning and continue unlocking the rest of
            the TARGETs.  Use
            --force to break a lock belonging to
            another user or working copy.
Unlock two files in your working copy:
$ svn unlock tree.jpg house.jpg 'tree.jpg' unlocked. 'house.jpg' unlocked.
Unlock a file in your working copy that is currently locked by another user:
$ svn unlock tree.jpg svn: E195013: 'tree.jpg' is not locked in this working copy $ svn unlock --force tree.jpg 'tree.jpg' unlocked.
Unlock a file without a working copy:
$ svn unlock http://svn.red-bean.com/repos/test/tree.jpg 'tree.jpg unlocked.
