To preserve user/group ownership and modification/access timestamps on files, use cp(1) with the -p flag. Maybe mc doesn't do that correctly on copying, though it should for a move, assuming that it uses mv(1) cheers, Ian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

This can be done from scripting languages such as python or perl, without having to write C programs. The ``touch'' command can change the modification times from any shell program, which may be all you need.
