lprm—Remove jobs from the line printer spooling queue
lprm [-P printer] [- job # …] [user …]
lprm will remove a job, or jobs, from a printer’s spool queue. Since the spooling directory is protected from users, using lprm is normally the only method by which a user may remove a job. The owner of a job is determined by the user’s login name and hostname on the machine where the lpr(1) command was invoked.
Options and arguments:
||Specify the queue associated with a specific printer; otherwise, the default printer is used.
||If a single – is given, lprm will remove all jobs that a user owns. If the superuser employs this flag, the spool queue will be emptied entirely.
||Causes lprm to attempt to remove any jobs queued belonging to that user (or users). This form of invoking lprm is useful only to the superuser.
A user may dequeue an individual job by specifying its job number. This number may be obtained from the lpq(1) program. For exampleA user may dequeue an individual job by specifying its job number. This number may be obtained from the lpq(1) program. For examplelpq – -l
(standard input) 100 bytes
If neither arguments nor options are given, lprm will delete the currently active job if it is owned by the user who invoked lprm.
lprm announces the names of any files it removes and is silent if there are no jobs in the queue that match the request list.
lprm 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 removals.
If the following environment variable exists, it is utilized by lprm:
PRINTER If the environment variable PRINTER exists, and a printer has not been specified with the -P option, the default printer is assumed from PRINTER.
