NAME

     lpq -- spool queue examination program

SYNOPSIS

     lpq [-a] [-l] [-Pprinter] [job # ...] [user ...]

DESCRIPTION

     The lpq utility 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.  The lpq utility 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.

     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 alternate default printer.

FILES

     /etc/printcap	To determine printer characteristics.
     /var/spool/*	The spooling directory, as determined from printcap.
     /var/spool/*/cf*	Control files specifying jobs.
     /var/spool/*/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

     A lpq utility 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.

NAME

     lprm -- remove jobs from the line printer spooling queue

SYNOPSIS

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

DESCRIPTION

     The lprm utility 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.  The owner of a job is determined by the user's login name and host name on the
     machine where the lpr(1) command was invoked.

     Options and arguments:

     -Pprinter
	     Specify the queue associated with a specific printer (otherwise the default printer is used).

     -	     If a single '-' is given, lprm will remove all jobs which a user owns.  If the super-user employs this flag, the spool queue will be
	     emptied entirely.

     user    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.

     job #   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

     If neither arguments or options are given, lprm will delete the currently active job if it is owned by the user who invoked lprm.

     The lprm 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.

     The lprm utility will kill off an active daemon, if necessary, before removing any spooling files.  If a daemon is killed, a new one is auto-
     matically restarted upon completion of file removals.

ENVIRONMENT

     If the following environment variable exists, it is utilized by lprm.

     PRINTER  If the environment variable PRINTER exists, and a printer has not been specified with the -P option, the default printer is assumed
	      from PRINTER.

FILES

     /etc/printcap	 Printer characteristics file.
     /var/spool/*	 Spooling directories.
     /var/spool/*/lock	 Lock file used to obtain the pid of the current daemon and the job number of the currently active job.

DIAGNOSTICS

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

SEE ALSO

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

HISTORY

     The lprm command appeared in 3.0BSD.

BUGS

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