 NAME
      pwck, grpck - password/group file checkers

 SYNOPSIS
      /usr/sbin/pwck [-s] [-l] [file]

      /usr/sbin/grpck [file]

 DESCRIPTION
      pwck scans the default password file or file and reports any
      inconsistencies to standard error.  The checks include validation of
      the number of fields, login name, user ID, group ID, and whether the
      login directory and optional program exist.  In addition, if the root
      entry shows a program, it can only be one of: /sbin/sh, /usr/bin/csh,
      /usr/bin/ksh, or /usr/bin/sh.  The criteria for validation is in
      passwd(4) and is described in the Managing Systems and Workgroups
      manual.  The default password file is /etc/passwd.

      grpck verifies all entries in the group file and reports any
      inconsistencies to standard error.  This verification includes a check
      of the number of fields, group name, group ID, and whether all login
      names appear in the password file.  The default group file is
      /etc/group.

    Options
      pwck recognizes the following options:

	   -s	   Check inconsistencies with the Protected Password
		   database.  It calls authck -p.

	   -l	   Check  encrypted password lengths that are greater than 8
		   characters.	If NIS+ is running with Trusted mode,
		   password lengths must not be longer than 8 characters.

 DIAGNOSTICS
      Group entries in /etc/group with no login names are flagged.

 WARNINGS
      Successful password file validation is not sufficient for proper
      system operation.	 To help maintain consistency with other system
      databases, editing of the password file with vipw is generally
      discouraged.  Please use sam, useradd, usermod, userdel, chfn, chsh or
      passwd to edit /etc/passwd.

 DEPENDENCIES
    NFS:
      pwck and grpck check only the local password and group files.  The
      Network Information Service database for password and group files is
      not checked.
