NAME
     group - group file

SYNOPSIS
     /etc/group

DESCRIPTION
     group contains for each group the following information:

     ⊕ group name

     ⊕ encrypted password

     ⊕ numerical group ID

     ⊕ a comma separated list of all users allowed in the group

     This is an ASCII file.  The fields are separated by colons;
     each group is separated from the next by a new-line.  If the
     password field is null, no password is demanded.

     This file resides in the /etc directory.  Because of the
     encrypted passwords, it can and does have general read per-
     mission and can be used, for example, to map numerical group
     ID's to names.

     A group file can have a line beginning with a plus (+),
     which means to incorporate entries from the Network Informa-
     tion Service.  There are two styles of + entries:  all by
     itself, + means to insert the entire contents of the Network
     Information Service group file at that point; +name means to
     insert the entry (if any) for name from the Network Informa-
     tion Service at that point.  If a + entry has a non-null
     password or group member field, the contents of that field
     will overide what is contained in the Network Information
     Service.  The numerical group ID field cannot be overridden.

EXAMPLE

          +myproject:::bill, steve
          +:

     If these entries appear at the end of a group file, then the
     group myproject will have members bill and steve, and the
     password and group ID of the Network Information Service
     entry for the group myproject.  All the groups listed in the
     Network Information Service will be pulled in and placed
     after the entry for myproject.
