NAME

lprrm - remove jobs from the line printer spooling queue

SYNOPSIS

lprrm [-Pprinter] [-] [job # ...] [user ...]

DESCRIPTION

Lprrm will remove a job, or jobs, from a printer's spool queue. Since the spooling directory is protected from users, using lprrm 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 host name on the machine where the lpr(1) command was invoked.

Options and arguments:

-Pprinter
Specify the queue associated with a specific printer (otherwise the default printer is used).

-
If a single `-' is given, lprrm will remove all jobs which a user owns. If the super-user employs this flag, the spool queue will be emptied entirely.

user
Causes lprrm to attempt to remove any jobs queued belonging to that user (or users). This form of invoking lprrm is useful only to the super-user.

job #
A user may dequeue an individual job by specifying its job number. This number may be obtained from the lprq(1) program.

If neither arguments or options are given, Lprrm will delete the currently active job if it is owned by the user who invoked lprrm.

Lprrm announces the names of any files it removes and is silent if there are no jobs in the queue which match the request list.

Lprrm 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.

ENVIRONMENT

If the following environment variable exists, it is utilized by lprrm.

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.

FILES

/etc/printcap
Printer characteristics file.

SEE ALSO

 lpr(1), lprq(1), lpd(8), lprc(1)

DIAGNOSTICS

``Permission denied" if the user tries to remove files other than his own.

BUGS

Since there are race conditions possible in the update of the lock file, the currently active job may be incorrectly identified.

HISTORY

The lprrm command appeared in 3.0BSD.

4.2 Berkeley Distribution May 9, 1991 2
