[SLUG] chgrp question and/or problem.
all, I havent had to do this for a while ie change group status as a USER, but now I do ... /tmp is a mounted partition.

Otherwise root can change UID and GID as it wishes. Non-root can't change UID of file. Non-root can't change GID of file if he isn't the owner. If non-root owns a file it can change the GID to any of the groups the changing process belongs to. Any change of GID is subject to quotas. Both for root and non-root processes: Change of UID turns suid off. Change of GID for group-executable turns sgid off. ... ... How come I cant change that bloody UID? (I can if I su root). jobst -- The email address in this email is used for Mailing Lists Only.
