.SH "BESKRIVNING"
.PP
The
\fBgrpck\fR
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\&.

.PP
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
\fBgroupmod\fR
command to correct the error\&.
.PP
The commands which operate on the
/etc/group
and /etc/gshadow files
are not able to alter corrupted or duplicated entries\&.
\fBgrpck\fR
should be used in those circumstances to remove the offending entries\&.
.SH "FLAGGOR"

By default,
