Often you need to look for a file belonging to a certain user or group. This is done with the -user and -group search operators. You often need to combine this with a search for particular permissions. To find all files that are set user ID ( 1.23 ) to root, use:
%find . -user root -perm -4000 -print
To find all files that are set group ID ( 1.23 ) to staff , use:
%find . -group staff -perm -2000 -print
Instead of using a name or group from /etc/passwd ( 36.3 ) or /etc/group ( 22.13 ) , you can use the UID or GID number ( 38.3 ) :
%find . -user 0 -perm -4000 -print
%find . -group 10 -perm -2000 -print
Often, when a user leaves a site, his account is deleted, but his files are still on the computer. Some versions of find have -nouser or -nogroup operators to find files with an unknown user or group ID.
