The

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

This option forces the removal of the user account, even if the user is still logged in\&. It also forces
|

\fBuserdel\fR

to remove the user\*(Aqs home directory and mail spool, even if another user uses the same home directory or if the mail spool is not owned by the specified user\&. If
