\fBgroupmod\fR [\fIoptions\fR] \fIGROUPE\fR
.SH "DESCRIPTION"
.PP
The
\fBgroupmod\fR
command modifies the definition of the specified
\fIGROUP\fR
by modifying the appropriate entry in the group database\&.
.SH "OPTIONS"
.PP
The options which apply to the
\fBgroupmod\fR
command are:
.PP
\fB\-g\fR, \fB\-\-gid\fR\ \&\fIGID\fR
.RS 4
The group ID of the given
\fIGROUP\fR
will be changed to
\fIGID\fR\&.
.sp
The value of
\fIGID\fR
must be a non\-negative decimal integer\&. This value must be unique, unless the
\fB\-o\fR
option is used\&.
.sp
Les utilisateurs qui utilisent ce groupe comme groupe primaire seront mis \(`a jour pour garder le groupe comme groupe primaire\&.
.sp
Any files that have the old group ID and must continue to belong to
\fIGROUP\fR, must have their group ID changed manually\&.
.sp
No checks will be performed with regard to the
\fBGID_MIN\fR,
\fBGID_MAX\fR,
\fBSYS_GID_MIN\fR, or
\fBSYS_GID_MAX\fR
from
/etc/login\&.defs\&.

.RS 4
Apply changes in the
\fIPREFIX_DIR\fR

.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\&.
