.SH DESCRIPTION
|
|
The \fBgroupadd\fR command creates a new group account using the values

|
specified on the command line and the default values from the system. The

.SH OPTIONS

|
The options which apply to the \fBgroupadd\fR command are:

|
|
This option causes to just exit with success status if the specified
|
|
group already exists. With \fB\-g\fR, if specified gid already exists,
|
|
other (unique) gid is chosen (i.e. \fB\-g\fR is turned off).
|
|
.IP "\fB\-g\fR \fIgid\fR"
|
|
The numerical value of the group's ID. This value must be unique, unless the
|
|
\fB\-o\fR option is used. The value must be non\-negative. The default is to
