GROUP(5)                  (2020-04-11)                   GROUP(5)

     NAME
          group - user group file

     DESCRIPTION
          The /etc/group file is a text file that defines the groups
          on the system.  There is one entry per line, with the fol-
          lowing format:

              group_name:password:GID:user_list

          The fields are as follows:

          group_name
               the name of the group.

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

          GID  the numeric group ID.

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

     FILES
          /etc/group

     BUGS
          As the 4.2BSD initgroups(3) man page says: no one seems to
          keep /etc/group up-to-date.
