will remove a job, or jobs, from a printer's spool queue.
51
Since the spooling directory is protected from users, using
53
is normally the only method by which a user may remove a job.
54
The owner of a job is determined by the user's login name
55
and host name on the machine where the

Options and arguments:

automatically restarted upon completion of file removals.
113
If the following environment variable exists, it is utilized by
