.HP \w'\fBgroupmod\fR\ 'u
\fBgroupmod\fR [\fIoptions\fR] \fIGROUP\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\&.
.SH "FLAGGOR"
.PP
The options which apply to the
\fBgroupmod\fR
command are:
.PP
\fB\-a\fR, \fB\-\-append\fR\ \&\fIGID\fR
.RS 4
If group members are specified with \-U, append them to the existing member list, rather than replacing it\&.
.RE
.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\&.
.RE

.RE
.PP
\fB\-n\fR, \fB\-\-new\-name\fR\ \&\fINEW_GROUP\fR

\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\&.

\fB\-p\fR, \fB\-\-password\fR\ \&\fIPASSWORD\fR
.RS 4
The encrypted password, as returned by
\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\&.

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
\fIPREFIX_DIR\fR
directory and use the configuration files from the

\fB\-U\fR, \fB\-\-users\fR
.RS 4
A list of usernames to add as members of the group\&.
