groups - Displays your group membership
The groups command writes to standard output the groups to
which you or the specified user belong. The Tru64 UNIX
operating system allows a user to belong to many different
groups at the same time.
Your primary group is specified in the /etc/passwd file.
Once you are logged in, you can change your active group
with the newgrp shell command (see sh). When you create a
file, its group ID is that of your active group.
Other groups that you belong to are specified in the
/etc/group file. If you belong to more than one group,
you can access files belonging to any of those groups
without changing your primary group ID. These are called
your concurrent groups.
