passwd(4)                                                         passwd(4)


   NAME
         passwd - password file

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

               login name
               dummy password
               numerical user ID
               numerical group ID
               comment
               initial working directory
               program to use as shell

         passwd is an ASCII file.  Each field within each user's entry is
         separated from the next by a colon.  The comment field can contain
         any desired information.  Each user is separated from the next by a
         new-line.  If the shell field is null, /usr/bin/sh is used.

         This file has user login information and general read permission.  It
         can therefore be used, for example, to map numerical user IDs to
         names.

         The password field consists of the character x.  This field remains
         only for compatibility reasons.  Password information is contained in
         the file /etc/shadow; see shadow(4).
