group(4)                         UNIX System V                         group(4)


NAME
      group - group file

DESCRIPTION
      The file /etc/group contains for each group the following information:

            group name
            encrypted password
            numerical group ID
            comma-separated list of all users allowed in the group

      group is an ASCII file.  The fields are separated by colons; each group
      is separated from the next by a new-line.

      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.

      During user identification and authentication, the supplementary group
      access list is initialized sequentially from information in this file.
      If a user is in more groups than the system is configured for,
      {NGROUPSMAX}, a warning will be given and subsequent group
      specifications will be ignored.
