.SH "SYNOPSIS"

\fBgrpck\fR [options] [\fIgroupe\fR\ [\ \fIshadow\fR\ ]]
.SH "DESCRIPTION"
.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\&.

.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 "OPTIONS"
.PP
The
\fB\-r\fR
and
\fB\-s\fR
options cannot be combined\&.
.PP
The options which apply to the
\fBgrpck\fR
command are:
.PP
\fB\-h\fR, \fB\-\-help\fR
.RS 4
Afficher un message d\*(Aqaide et quitter\&.
.RE
.PP
\fB\-r\fR, \fB\-\-read\-only\fR
.RS 4
Execute the
\fBgrpck\fR
command in read\-only mode\&. This causes all questions regarding changes to be answered
\fIno\fR
without user intervention\&.
.RE
.PP
\fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR
.RS 4
Apply changes in the
\fICHROOT_DIR\fR
directory and use the configuration files from the
\fICHROOT_DIR\fR
directory\&.
.RE
.PP
\fB\-s\fR, \fB\-\-sort\fR
.RS 4
Sort entries in
/etc/group
and /etc/gshadow
by GID\&.
.RE
.PP
\fB\-S\fR, \fB\-\-silence\-warnings\fR
.RS 4
Suppress more controversial warnings, in particular warnings about inconsistency between group members listed in
/etc/group
and
/etc/ghadow\&.
.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 "CONFIGURATION"
.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
La valeur par d\('efaut est 0, ce qui signifie qu\*(Aqil n\*(Aqy a pas de limites pour le nombre de membres dans un groupe\&.
.sp
Cette fonctionnalit\('e (groupe d\('ecoup\('e) permet de limiter la longueur des lignes dans le fichier de groupes\&. Ceci est utile pour s\*(Aqassurer que les lignes pour les groupes NIS ne sont pas plus grandes que 1024 caract\(`eres\&.
.sp
Si vous avez besoin de configurer cette limite, vous pouvez utiliser 25\&.
.sp
Remarque\ \&: les groupes d\('ecoup\('es ne sont peut\-\(^etre pas pris en charge par tous les outils (m\(^eme dans la suite d\*(Aqoutils Shadow)\&. Vous ne devriez pas utiliser cette variable, sauf si vous en avez vraiment besoin\&.
