     GROUP(5)                                                 GROUP(5)

          group - group file

          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 new-line.  If the
          password field is null, no password is demanded.

          This file resides in directory /etc.  Because of the
          encrypted passwords, it can and does have general read per-
          mission and can be used, for example, to map numerical group
          ID's to names.
