.Dd June 6, 1993 .Dt LPRM 1 .Os .Sh NAME .Nm lprm .Nd remove jobs from the line printer spooling queue .Sh SYNOPSIS .Nm .Op Fl P Ns Ar printer .Op Fl .Op job # ...\& .Op Ar user ...\& .Sh DESCRIPTION The .Nm utility will remove a job, or jobs, from a printer's spool queue. Since the spooling directory is protected from users, using .Nm 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 .Xr lpr 1 command was invoked.
p Options and arguments: l -tag -width indent t Fl P Ns Ar printer Specify the queue associated with a specific .Ar printer (otherwise the default printer is used). t Fl If a single .Sq Fl is given, .Nm will remove all jobs which a user owns. If the super-user employs this flag, the spool queue will be emptied entirely. t Ar user Cause .Nm to attempt to remove any jobs queued belonging to that user (or users). This form of invoking .Nm is useful only to the super-user. t Ar job # A user may dequeue an individual job by specifying its job number. This number may be obtained from the .Xr lpq 1 program, e.g.\& d -literal -offset indent % lpq -l 1st:ken [job #013ucbarpa] (standard input) 100 bytes % lprm 13 .Ed .El
p If neither arguments or options are given, .Nm will delete the currently active job if it is owned by the user who invoked .Nm .
p The .Nm utility announces the names of any files it removes and is silent if there are no jobs in the queue which match the request list.
p The .Nm utility 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. .Sh ENVIRONMENT If the following environment variable exists, it is utilized by .Nm . l -tag -width PRINTER t Ev PRINTER If the environment variable .Ev PRINTER exists, and a printer has not been specified with the .Fl P option, the default printer is assumed from .Ev PRINTER . .El .Sh FILES l -tag -width /var/spool/*/lock/ -compact t Pa /etc/printcap Printer characteristics file. t Pa /var/spool/* Spooling directories. t Pa /var/spool/*/lock Lock file used to obtain the pid of the current daemon and the job number of the currently active job. .El .Sh DIAGNOSTICS ``Permission denied" if the user tries to remove files other than his own. .Sh SEE ALSO .Xr lpq 1 , .Xr lpr 1 , .Xr lpd 8 .Sh HISTORY The .Nm command appeared in x 3.0 . .Sh BUGS Since there are race conditions possible in the update of the lock file, the currently active job may be incorrectly identified.
