    PASSWD(V)                    9/10/73                    PASSWD(V)

    NAME
         passwd - password file

    DESCRIPTION
         Passwd contains for each user the following information:

              name (login name, contains no upper case)
              encrypted password
              numerical user ID
              numerical group ID (for now, always 1)
              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 us-
         er  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 en-
         crypted passwords, it can and does have general read permis-
         sion  and  can  be  used, for example, to map numerical user
         ID's to names.
