My groups are staff, uucp and admin.
and in locks (with ls -la) we have:
drwxrwxr-x 2 root uucp 68 Dec 14 00:18 .
drwxr-xr-x 31 root wheel 1054 Dec 31 16:44 ..
I know it's off topic but if you know what "wheel" is I wouldn't mind knowing...
Also should i be deleting the lock folder, since it's empty?
