group(4)                   DG/UX 4.30                    group(4)



     NAME
          group - group file

     SYNOPSIS
          /etc/group

     DESCRIPTION
          Group contains for each group the following information:

          ⊕ group name

          ⊕ encrypted password

          ⊕ numerical group id

          ⊕ a comma-separated list of all users allowed in the group

          This is an ASCII file.  The fields are separated by colons;
          each group is separated from the next by a newline.  If the
          password field is null, no password is demanded.

          This file resides in the /etc directory.  Because of the
          encrypted passwords, it can and does have general read
          permission and can be used, for example, to map numerical
          group IDs to names.

          A group file can have a line beginning with a plus sign (+),
          which means to incorporate entries from the Yellow Pages
          (YP).

          NOTE:
               You must be using the DG/UX Open Network
               Computing/Network File System (ONC/NFS) to use this
               feature.

          There are two styles of + entries:  By itself, + means to
          insert the entire contents of the YP group file at that
          point; +name means to insert the entry (if any) for name
          from the YP at that point.  If a + entry has a non-null
          password or group member field, the contents of that field
          will override what is contained in the YP.  The numerical
          group ID field cannot be overridden.

          Entries beginning with a minus (-) are also allowed, and
          have the format -name, which means to consider name to not
          be in the group file, regardless of subsequent entries to
          the contrary.  Minus entries can be used to exclude specific
          groups that are present in the YP group database.

          Grpck can be used to verify entries in the group file. See
          pwck(1M) in the System Manager's Reference for the DG/UX
          System.

     EXAMPLE
          +myproject:::bill, steve
          +:

          If these entries appear at the end of a group file, then the
          group will have members bill and steve and the password and
          group ID of the YP entry for the group myproject.  All the
          groups listed in the Yellow Pages will be pulled in and
          placed after the entry for myproject.

     FILES

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

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