PASSWD(5)                                               PASSWD(5)

          passwd - password file

          Passwd contains for each user the following information:

          name (login name, contains no upper case)
          encrypted password
          numerical user ID
          numerical group ID
          GCOS job number, box number, optional GCOS user-id
          initial working directory
          program to use as Shell

          This is an ASCII file.  Each field within each user's entry
          is separated from the next by a colon.  The GCOS field is
          used only when communicating with that system, and in other
          installations can contain any desired information.  Each
          user is separated from the next by a new-line.  If the pass-
          word field is null, no password is demanded; if the Shell
          field is null, the Shell itself is used.

          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 user
          ID's to names.
