What could be a command to find all files owned by "abc" user, I guess that can be extended to finding all files with group 'def'.
e.g.
if I got result (ls -l) such as one shown below
-rwxrw-r-- 1 apache web 1981 2009-01-22 08:10 unsubscribe.php
then I would like to find all files owned by apache or group web
Thanks!
