Go to the first, previous, next, last section, table of contents.
- Test: -user uname
-
- Test: -group gname
-
True if the file is owned by user uname (belongs to group gname).
A numeric ID is allowed.
- Test: -uid n
-
- Test: -gid n
-
True if the file's numeric user ID (group ID) is n. These tests
support ranges (`+n' and `-n'), unlike
`-user' and `-group'.
- Test: -nouser
-
- Test: -nogroup
-
True if no user corresponds to the file's numeric user ID (no group
corresponds to the numeric group ID). These cases usually mean that the
files belonged to users who have since been removed from the system.
You probably should change the ownership of such files to an existing
user or group, using the
chown
or chgrp
program.
