lprm

LPRM(1) 						      General Commands Manual							   LPRM(1)

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 nor-
       mally 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 emp-
       tied entirely. The owner is determined by the user's login name and host name on the machine where the lpr 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 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.

       The  -P	option	may  be  usd  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.
