NAME

  groups - Displays your group membership

SYNOPSIS

  groups [user]

DESCRIPTION

  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.

NOTES

  The /etc/passwd and /etc/group files must be on the same node.

EXAMPLES

  To determine your group membership, enter:

       groups

  The groups to	which you belong will be displayed.  For example:

       devel  prod
