NAME
lprm - remove jobs from the line printer spooling queue

SYNOPSIS
lprm [ -Pprinter ] [ - ] [ job # ... ] [ user ... ]

DESCRIPTION
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.

Lprm without any arguments will delete the currently active job if
it is owned by the user who invoked lprm.

If the - flag is specified, lprm 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 lpr(1) command was invoked.

Specifying a user’s name, or list of user names, will cause lprm to
attempt to remove any jobs queued belonging to that user (or
users). This form of invoking lprm 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 lpq(1) program, e.g.

% lpq -l
1st: ken [job #013ucbarpa]
(standard input) 100 bytes
% lprm 13

Lprm 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.

Lprm will kill 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.

The -P option may be used 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).

FILES
/etc/printcap printer characteristics file
/usr/spool/* spooling directories
/usr/spool/*/lock lock file used to obtain the pid of the current
daemon and the job number of the currently active job

SEE ALSO
lpr(1), lpq(1), lpd(8)

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.
