passwd(4)                        UNIX System V                        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).
