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.

NAME

     lpq -- spool queue examination program

SYNOPSIS

     lpq [-al] [-P printer] [-w maxwait] [job# ...] [user ...]

DESCRIPTION

     lpq examines the spooling area used by lpd(8) for printing files on the line printer, and reports the status of the specified jobs or all
     jobs associated with a user.  lpq invoked without any arguments reports on any jobs currently in the queue.

     Options:

     -P      Specify a particular printer, otherwise the default line printer is used (or the value of the PRINTER variable in the environment).
	     All other arguments supplied are interpreted as user names or job numbers to filter out only those jobs of interest.

     -l      Information about each of the files comprising the job entry is printed.  Normally, only as much information as will fit on one line
	     is displayed.

     -a      Report on the local queues for all printers, rather than just the specified printer.

     -w maxwait
	     Specify the maximum time to wait in seconds for remote responses.	The default is 300 seconds or 5 minutes.

     For each job submitted (i.e. invocation of lpr(1)) lpq reports the user's name, current rank in the queue, the names of files comprising the
     job, the job identifier (a number which may be supplied to lprm(1) for removing a specific job), and the total size in bytes.  Job ordering
     is dependent on the algorithm used to scan the spooling directory and is supposed to be FIFO (First in First Out).  File names comprising a
     job may be unavailable (when lpr(1) is used as a sink in a pipeline) in which case the file is indicated as ``(standard input)''.

     If lpq warns that there is no daemon present (i.e. due to some malfunction), the lpc(8) command can be used to restart the printer daemon.

ENVIRONMENT

     If the following environment variable exists, it is used by lpq:

     PRINTER  Specifies an alternative default printer.

FILES

     /etc/printcap	       To determine printer characteristics.
     /var/spool/output/*       The spooling directory, as determined from printcap.
     /var/spool/output/*/cf*   Control files specifying jobs.
     /var/spool/output/*/lock  The lock file to obtain the currently active job.

DIAGNOSTICS

     Unable to open various files.  The lock file being malformed.  Garbage files when there is no daemon active, but files in the spooling direc-
     tory.

SEE ALSO

     lpr(1), lprm(1), lpc(8), lpd(8)

HISTORY

     lpq appeared in 3BSD.

BUGS

     Due to the dynamic nature of the information in the spooling directory lpq may report unreliably.	Output formatting is sensitive to the line
     length of the terminal; this can results in widely spaced columns.
