     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
          the program-to-use-as-Shell 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.

     FILES
          /etc/group
          /etc/passwd

     SEE ALSO
          group(4), passwd(4) in the Programmer's Reference Manual.

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