group(4)                       DG/UX 5.4R3.00                       group(4)


NAME
       group - group file

SYNOPSIS
       /etc/group

DESCRIPTION
       Group is an ASCII file containing a one-line entry for each group
       recognized by the system.  The file format is as follows:

              groupname:password:gid:user-list

       where:
              groupname   The name of the group.
              password    An encrypted password.
              gid         The group's numerical ID within the system; it
                          must be unique.
              user-list   A comma-separated list of users allowed in the
                          group.

       If the password field is empty, no password is demanded.  Because of
       the encrypted passwords, the group file can and does have general
       read permission and can be used, for example, to map numerical group
       IDs to names.

       Malformed entries cause routines that read this file to halt, in
       which case group assignments specified further along are never made.
       grpck can be used to verify entries in the group file.  See pwck(1M).

       NOTE:  Users listed as members of a specific group in etc/group are
              only those users who have that group as a supplementary group.
              The group list does not contain the users who have that group
              as their primary group, unless they also have that group as a
              supplementary group.  This list is used by the system to
              initialize the supplementary group list when a session is
              created for a user.

   ONC/NFS Features
       If you are using the DG/UX Open Network Computing/Network File System
       (ONC/NFS), a group file can have a line beginning with a plus sign
       (+), which means to incorporate an entry or entries from the Network
       Information Service (NIS).  There are two styles of + entries.  By
       itself, + means to insert the entire contents of the NIS group file
       at that point; +groupname means to insert the entry (if any) for
       groupname.  If a + entry has a non-empty password or user-list field,
       the contents of that field override the corresponding field from the
       NIS.  The gid field cannot be overridden in this way.

       An entry can also begin with a minus (-); -groupname means to
       disallow groupname.  All subsequent entries for the indicated
       groupname, whether originating from the NIS or the local group file,
       are ignored.

group(4)                       DG/UX 5.4R3.00                       group(4)


EXAMPLE
       primary:q.mJzTnu8icF.:10:fred,mary
       +myproject:::bill,steve
       +:

       If these entries appear at the end of a group file, then the group
       primary will have members fred and mary, and a group ID of 10.  The
       group myproject will have members bill and steve, and the password
       and group ID of the NIS entry for the group myproject.  All groups
       listed in the NIS are pulled in and placed after the entry for
       myproject.

FILES

       passwd(1), su(1), pwck(1M).

NOTES
       The passwd(1) command won't change group passwords.

       Normally, group-ids less than 100 are reserved for system-level use
       (DG/UX software).
