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

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