     NAME
          pwck, grpck - password/group file checkers

     SYNOPSIS
          /etc/pwck [file]
          /etc/grpck [file]

     DESCRIPTION
          pwck scans the password file and notes any inconsistencies.
          The checks include validation of the number of fields, login
          name, user ID, group ID, and whether the login directory and
          optional program name exist.  The default password file is
          /etc/passwd.

          grpck verifies all entries in the group file. 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.
