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

.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\&.

.PP
\fB\-R\fR, \fB\-\-root\fR \fICHROOT_DIR\fR

.PP
The following configuration variables in

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\&.
