\fBgroupmod\fR [\fIflaggor\fR] \fIGRUPP\fR
.SH "BESKRIVNING"
.PP
The
\fBgroupmod\fR
command modifies the definition of the specified
\fIGROUP\fR
by modifying the appropriate entry in the group database\&.

.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
Users who use the group as primary group will be updated to keep the group as their primary group\&.
.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
The name of the group will be changed from
\fIGROUP\fR
to
\fINEW_GROUP\fR
name\&.
.RE
.PP
\fB\-o\fR, \fB\-\-non\-unique\fR
.RS 4
When used with the
\fB\-g\fR
option, allow to change the group
\fIGID\fR
to a non\-unique value\&.
.RE
.PP
\fB\-p\fR, \fB\-\-password\fR\ \&\fIL\(:OSENORD\fR
.RS 4

\fBcrypt\fR(3)\&.
.sp
\fBNote:\fR
This option is not recommended because the password (or encrypted password) will be visible by users listing the processes\&.
.sp
You should make sure the password respects the system\*(Aqs password policy\&.
.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
.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
The default value is 0, meaning that there are no limits in the number of members in a group\&.
.sp
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\&.
.sp
If you need to enforce such limit, you can use 25\&.
.sp
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\&.
