USERS(6)                                                 USERS(6)

     NAME
          users - file server user list format

     DESCRIPTION
          The permanent file servers each maintain a private list of
          users and groups, in /adm/users by convention.  Each line in
          the file has the format

               num:name:leader:members

          where num is a decimal integer, name and leader are print-
          able strings excluding the characters `?', `=', `+', `-',
          `/', and `:', and members is a comma-separated list of such
          strings.  Such a line defines a user and a group with the
          given name; the group has a group leader given by leader and
          group members given by the user names in members. The leader
          field may be empty, in which case any group member is a
          group leader.  The members field may be empty.

          Lines beginning with `#' are ignored.

          The num in a line is a number used internally by a file
          server; there should be no duplicate nums in the file.  A
          negative num is special: a user with a negative num cannot
          attach to the file server.  The file /adm/users itself is
          owned by user adm, having a negative num, and write pro-
          tected to others, so it can only be changed via console com-
          mands.
