NAME
pwck, grpck - password/group file checkers
SYNOPSIS
/usr/sbin/pwck [-s][-l][file]
/usr/sbin/grpck [file ]
DESCRIPTION
pwck scans the default password file or file and reports any inconsistencies to standard error. The checks
include validation of the number of fields, login name, user ID, group ID, and whether the login directory
and optional program exist. In addition, if the root entry shows a program, it can only be one of:
/sbin/sh, /usr/bin/csh , /usr/bin/ksh,or/usr/bin/sh . The criteria for validation is in
passwd(4) and is described in the Managing Systems and Workgroups manual. The default password file is
/etc/passwd .
grpck verifies all entries in the group file and reports any inconsistencies to standard error. 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.
Options
pwck recognizes the following options:
-s Check inconsistencies with the Protected Password database. It calls
authck -p.
-l Check encrypted password lengths that are greater than 8 characters. If NIS+ is running
with Trusted mode, password lengths must not be longer than 8 characters.
DIAGNOSTICS
Group entries in
/etc/group with no login names are flagged.
WARNINGS
Successful password file validation is not sufficient for proper system operation. To help maintain con-
sistency with other system databases, editing of the password file with vipw is generally discouraged.
Please use
sam, useradd, usermod, userdel, chfn, chsh or passwd to edit /etc/passwd
.
DEPENDENCIES
NFS:
pwck and grpck check only the local password and group files. The Network Information Service data-
base for password and group files is not checked.
