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 DIGITAL 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

FILES
  /etc/group
      Contains group information.
