DESCRIPTION         top

       /etc/group is a text file which defines the groups on the system.  There is
       one entry per line, with the following format:

              group_name:passwd:GID:user_list

       The field descriptions are:

       group_name
              the name of the group.

       password
              the (encrypted) group password.  If this field is empty, no password is
              needed.

       GID    the numerical group ID.

       user_list
              a list of the usernames that are members of this group, separated by
              commas.
