- _L_p_r_m will remove a job, or jobs, from a printer's spool
- queue. Since the spooling directory is protected from
- users, using _l_p_r_m is normally the only method by which a
- user may remove a job.
-
- _L_p_r_m without any arguments will delete the currently active
- job if it is owned by the user who invoked _l_p_r_m.
-
- If the -- flag is specified, _l_p_r_m will remove all jobs which
- a user owns. If the super-user employs this flag, the spool
- queue will be emptied entirely. The owner is determined by
- the user's login name and host name on the machine where the
- _l_p_r command was invoked.
-
- Specifying a user's name, or list of user names, will cause
- _l_p_r_m to attempt to remove any jobs queued belonging to that
- user (or users). This form of invoking _l_p_r_m is useful only
- to the super-user.
-
- A user may dequeue an individual job by specifying its job
- number. This number may be obtained from the _l_p_q(1) pro-
- gram, e.g.
-
- % lpq -l
-
- 1st: ken [job #013ucbarpa]
- (standard input) 100 bytes
- % lprm 13
-
- _L_p_r_m will announce the names of any files it removes and is
- silent if there are no jobs in the queue which match the
- request list.
-
- _L_p_r_m will kill off an active daemon, if necessary, before
- removing any spooling files. If a daemon is killed, a new
- one is automatically restarted upon completion of file remo-
- vals.
-
- The --PP option may be usd to specify the queue associated
- with a specific printer (otherwise the default printer, or
- the value of the PRINTER variable in the environment is
- used).

- the lock file, the currently active job may be incorrectly
