      NAME
           group - group file

      DESCRIPTION
           /etc/group allows a password to be associated with user
           groups, and records which users are allowed to execute
           newgrp(1) to gain access to each group.  (Groups are
           established by assigning group numbers to users in the
           /etc/passwd file.) /etc/group is an ascii file for
           associating passwords with groups.  It contains the
           following information for each group:

           name : encrypted-password : group-ID-num : list-of-users

           The fields are separated by colons. Additional group entries
           appear on separate lines.

           Name is the group-name used in newgrp(1) and chgrp(1).

           Encrypted-password should not be used.  If the password
           field is null, no password is demanded.

           Group-ID-num corresponds to the field of the same name in
           the /etc/passwd file.

           List-of-users is a list of user ID names, separated by
           commas, who are allowed to use newgrp(1) to enter this
           group.

           This file has general read permission so that the encrypted
           passwords can be read.  It can be used, for example, to map
           numerical group ID's to names.
