NAME
userdbck - verify or fix information in the user database, /var/adm/userdb
SYNOPSIS
/usr/sbin/userdbck
[-a][-u][
-r][-f][file]
DESCRIPTION
userdbck verifies the information in the user database (
/var/adm/userdb
), reports inconsistencies,
and fixes problems.
If no options and no arguments are specified,
userdbck reports all data corruption problems in all files in
/var/adm/userdb
.
If the
-r option is also specified, each reported problem is repaired.
If a file argument (hex 00-ff) is specified, only that file in the
/var/adm/userdb
directory is verified.
Options
The following options are recognized:
-a Verify attributes. Information in /etc/security.dsc
is used to report any attribute that is
not valid, not allowed in the user database, has an invalid value, or is allowed only for a local
user and the user is not in
/etc/passwd .
-f Normally when the user database is disabled (see userdb(4)), userdbck immediately exits
without verifying or repairing the database. The -f option overrides this and forces userdbck
to verify or repair the database.
-u Verify user names. User names found in the database are reported if they do not exist in any of
the repositories defined in /etc/nsswitch.conf
. This option could take a long time on a
system with many users.
-r Repair all data corruption problems that are found. If this option is not specified, problems are
reported but not repaired.
Notes
Only users who have read and write access to
/var/adm/userdb
can run userdbck.
RETURN VALUE
userdbck exits with one of the following values:
0 success: no inconsistencies were found
1 inconsistencies were found and fixed
2 invalid usage
3 database is disabled; see userdb(4)
4 inconsistencies were found but not fixed, because the
-r option was not specified
5 a problem was found that could not be fixed
