svn lock — Lock working copy paths or URLs in the repository so that no other user can commit changes to them.
Lock each TARGET. If any
TARGET is already locked by
another user, print a warning and continue locking the
rest of the TARGETs. Use
--force to steal a lock from another user
or working copy.
Lock two files in your working copy:
$ svn lock tree.jpg house.jpg 'tree.jpg' locked by user 'harry'. 'house.jpg' locked by user 'harry'.
Lock a file in your working copy that is currently locked by another user:
$ svn lock tree.jpg
svn: warning: Path '/tree.jpg is already locked by user 'sally in \
filesystem '/var/svn/repos/db'
$ svn lock --force tree.jpg
'tree.jpg' locked by user 'harry'.
Lock a file without a working copy:
$ svn lock http://svn.red-bean.com/repos/test/tree.jpg 'tree.jpg' locked by user 'harry'.
