GROUPS(1)                     User Commands                    GROUPS(1)

NAME

       groups - display current group names

SYNOPSIS

       groups [user]

DESCRIPTION

       The groups command displays the current group names or ID values.
       If the value does not have a corresponding entry in /etc/group,
       the value will be displayed as the numerical group value. The
       optional user parameter will display the groups for the named
       user.

NOTE

       Systems which do not support supplementary groups (see
       initgroups(3)) will have the information from /etc/group
       reported. The user must use newgrp or sg to change his current
       real and effective group ID.

FILES

       /etc/group
           Group account information.

SEE ALSO

       newgrp(1), getgid(2), getgroups(2), getuid(2), initgroups(3).
