+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\&.

+.RE
+.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 "OPTIONEN"
+.PP
+The
+\fB\-r\fR
+and
+\fB\-s\fR
+options cannot be combined\&.
+.PP
+The options which apply to the
+\fBgrpck\fR

+.RE
+.PP

+without user intervention\&.

+Sort entries in

+.RE
+.PP
+By default,
+\fBgrpck\fR
+operates on
+/etc/group
+and /etc/gshadow\&. The user may select alternate files with the
+\fIgroup\fR
+and \fIshadow\fR parameters\&.
+.SH "KONFIGURATION"
+.PP
+The following configuration variables in
+/etc/login\&.defs
+change the behavior of this tool:
+.PP
+\fBMAX_MEMBERS_PER_GROUP\fR (number)
+.RS 4
+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)\&.
+.sp
+Der Standardwert ist 0, was zur Folge hat, dass die Anzahl der Mitglieder einer Gruppe nicht begrenzt ist\&.
+.sp
+Diese F\(:ahigkeit (der aufgeteilten Gruppe) erm\(:oglicht es, die Zeilenl\(:ange in der Gruppendatei zu begrenzen\&. Damit kann sichergestellt werden, dass die Zeilen f\(:ur NIS\-Gruppen nicht l\(:anger als 1024 Zeichen sind\&.
+.sp
+Falls Sie eine solche Begrenzung ben\(:otigen, k\(:onnen Sie 25 verwenden\&.
+.sp
+Hinweis: Aufgeteilte Gruppen werden m\(:oglicherweise nicht von allen Werkzeugen unterst\(:utzt, selbst nicht aus der Shadow\-Werkzeugsammlung\&. Sie sollten diese Variable nur setzen, falls Sie zwingend darauf angewiesen sind\&.
