GRPCK(8) System Management Commands GRPCK(8)
NAME
grpck - verify integrity of group files
SYNOPSIS
grpck [-r] [group [ shadow ]]
grpck [-s] [group [ shadow ]]
DESCRIPTION
The grpck command verifies the integrity of the groups information. It checks that all entries in /etc/group and /etc/gshadow have the
proper format and contain valid data. The user is prompted to delete entries that are improperly formatted or which have other
uncorrectable errors.
Checks are made to verify that each entry has:
o the correct number of fields
o a unique and valid group name
o a valid group identifier (/etc/group only)
o a valid list of members and administrators
o a corresponding entry in the /etc/gshadow file (respectively /etc/group for the gshadow checks)
The checks for correct number of fields and unique group name are fatal. If an 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 duplicated
group name is prompted for deletion, but the remaining checks will still be made. All other errors are warnings and the user is encouraged
to run the groupmod command to correct the error.
The commands which operate on the /etc/group and /etc/gshadow files are not able to alter corrupted or duplicated entries. grpck should be
used in those circumstances to remove the offending entries.
OPTIONS
The options which apply to the grpck command are:
-r
Execute the grpck command in read-only mode. This causes all questions regarding changes to be answered no without user intervention.
-s
Sort entries in /etc/group and /etc/gshadow by GID.
By default, grpck operates on /etc/groupand /etc/gshadow. The user may select alternate files with the group and shadow parameters.
CONFIGURATION
The following configuration variables in /etc/login.defs change the behavior of this tool:
MAX_MEMBERS_PER_GROUP (number)
Maximum members per group entry. When the maximum is reached, a new group entry (line) is started in /etc/group (with the same name,
same password, and same GID).
The default value is 0, meaning that there are no limits in the number of members in a group.
This feature (split group) permits to limit the length of lines in the group file. This is useful to make sure that lines for NIS
groups are not larger than 1024 characters.
If you need to enforce such limit, you can use 25.
Note: split groups may not be supported by all tools (even in the Shadow toolsuite). You should not use this variable unless you really
need it.
FILES
/etc/group
Group account information.
/etc/gshadow
Secure group account information.
/etc/passwd
User account information.
EXIT VALUES
The grpck command exits with the following values:
0
success
1
invalid command syntax
2
one or more bad group entries
3
can't open group files
4
can't lock group files
5
can't update group files
