The

.PP

\fB\-f\fR, \fB\-\-force\fR
|

.RS 4

This option causes the command to simply exit with success status if the specified group already exists\&. When used with

\fB\-g\fR, and the specified GID already exists, another (unique) GID is chosen (i\&.e\&.

\fB\-o\fR

option is used\&. The value must be non\-negative\&. The default is to use the smallest ID value greater than or equal to
