NAME
       pwck, grpck - check password or group file

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

   where:
       file   The pathname of a password or group file; default =
              /etc/passwd for pwck, /etc/group for grpck.

DESCRIPTION
       Pwck scans the password file 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-
       to-use-as-shell exist.  The criteria for determining a valid login
       name are described in Managing the DG/UX (Trademark) System.

       Grpck verifies all entries in the group file.  This verification
       includes a check of the number of fields, group name, group ID,
       whether any login names belong to more than NGROUPS_MAX groups and
       that all login names appear in the password file.  The fields for the
       password and login names may be empty.

FILES
       /etc/group
       /etc/passwd

DIAGNOSTICS
       For each line with some inconsistency, the line is displayed followed
       by an explanation of the problem.

SEE ALSO

NOTE
       DG/UX (Trademark) supports some characters in user login names that
       are identified as invalid by pwck.  These characters include '_',
       '.', and '-'.
