PWCK(1) General Commands Manual PWCK(1)
NAME
pwck - verify integrity of password files
SYNOPSIS
pwck [-sr] [passwd shadow]
DESCRIPTION
pwck verifies the integrity of the system authentication information. All entries in the /etc/passwd and /etc/shadow are checked to see
that the entry has the proper format and valid data in each field. The user is prompted to delete entries that are improperly formatted or
which have other incorrectable errors.
Checks are made to verify that each entry has
- the correct number of fields
- a unique user name
- a valid user and group identifier
- a valid primary group
- a valid home directory
- a valid login shell
The checks for correct number of fields and unique user name are fatal. If the entry has the wrong number of fields, the user will be
prompted to delete the entire line. If the user does not answer affirmatively, all further checks are bypassed. An entry with a dupli-
cated user name is prompted for deletion, but the remaining checks will still be made. All other errors are warning and the user is
encouraged to run the usermod command to correct the error.
The commands which operate on the /etc/passwd file are not able to alter corrupted or duplicated entries. pwck should be used in those
circumstances to remove the offending entry.
OPTIONS
By default, pwck operates on the files /etc/passwd and /etc/shadow. The user may select alternate files with the passwd and shadow parame-
ters. Additionally, the user may execute the command in read-only mode by specifying the -r flag. This causes all questions regarding
changes to be answered no without user intervention. pwck can also sort entries in /etc/passwd and /etc/shadow by UID. To run it in sort
mode pass it -s flag. No checks are performed then, it just sorts.
FILES
/etc/passwd - user account information
/etc/shadow - encrypted password information
/etc/group - group information
SEE ALSO
group(5), passwd(5), shadow(5), usermod(8)
DIAGNOSTICS
The pwck command exits with the following values:
0 Success
1 Syntax Error
2 One or more bad password entries
3 Cannot open password files
4 Cannot lock password files
5 Cannot update password files
