Name
       lprm - remove jobs from line printer queue

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

Description
       The  command removes a job, or jobs, from a printer's spool queue.  Since the spooling directory is protected from users, using is normally
       the only method by which a user may remove a job.

       The command without any arguments deletes the currently active job if it is owned by the user who invoked

       If the - flag is specified, removes all jobs which a user owns.	If the super-user employs this flag, the spool queue is emptied  entirely.
       The owner is determined by the user's login name and host name on the machine where the command was invoked.

       Specifying  a user's name, or list of user names, causes to attempt to remove any jobs queued belonging to that user (or users).  This form
       of invoking 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 program.  For example,
       % lpq -l

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

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

       The command kills off an active daemon, if necessary, before removing any spooling files.  If a daemon is killed, a new	one  is  automati-
       cally restarted upon completion of file removals.

Options
       -		   Removes all jobs owned by you only.

       -P printer	   Removes jobs from specified printer.  It 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).

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

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

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
