Groups

The concept of a group is a collection of users. If you belong to a certain group, and a set of files give you special group permissions, you inherit those permissions. For example, if you're a member of group staff, and the following file has permissions:

-rw-r-----  1 tot    staff        2437 Sep  8 18:12 foo

You may read the file `foo'. On most systems you can issue the command groups and it will list all groups to which you belong.
