   NAME
         pwck - check password database entries

   SYNOPSIS
         /usr/ucb/pwck [ filename ]

   DESCRIPTION
         pwck checks a password file for errors.  If specified, filename is
         checked, otherwise /etc/passwd is checked.

         This command differs from /usr/sbin/pwck in its ability to correctly
         parse YP entries in /etc/passwd.

         Login directory not found

               that does not exist.
