Diffferentiate group from users

permalink · #1 (**permalink**) 07-20-2009

Im trying to put all the groups in into a variable called $GROUP, however in /etc/group there are also lotsa users. And the GID of group can differ as it can be set, this there is no specific range, how can i put all the names of the groups into that variable?

Code:

GROUPS=$(cut -d: -f1 /etc/group)

The further code does not differentiate groups from users, it only displays the first column... any other solution to display GROUPS only ?

Just as a hint: /etc/password only contains users in the first field, /etc/group only users, even if they sometimes have the same name.
