lpq(1)								       lpq(1)


  lpq -	Examines the spool queues.


  lpq [+] [number] [-l]	[-Pprinter] [request-ID...] [user...]


  -l  Displays information about each of the files comprising the printer

      Specifying printer displays requests queued for that printer only.

      Displays the spool queue until it	empties. Sleeps	number seconds
      between scans of the queue if number is specified.


  The lpq command examines the spooling	area used by lpd for printing files
  on the line printer and reports the status of	the specified requests or all
  requests associated with a user.

  The lpq command invoked without any arguments	reports	on any requests
  currently in the queue. The -P option	can be used to specify a particular
  printer; otherwise, the default line printer is used (or the value of	the
  PRINTER environment variable).

  Specifying one or more request-IDs displays only the specified requests.
  Specifying one or more users displays	print requests from those users	only.

  If you specify the + argument, lpq displays the spool	queue until it emp-
  ties.	 Supplying a number immediately	after the + argument indicates that
  lpq should sleep number seconds in between scans of the queue.  All other
  arguments supplied are interpreted as	user or	request-ID arguments to
  display only those requests of interest.

  For each request submitted (that is, each request invoked by lp or lpr),
  lpq reports the user's name, current rank in the queue, the names of files
  comprising the request, the request ID (a number that	you can	use to iden-
  tify the request to other commands, such as lprm) and	the total size of the
  job in bytes.

  The -l option	causes information about each of the files comprising the
  request to be	displayed; without it, only as much information	as will	fit
  on one line is displayed.  Job ordering depends on the algorithm used	to
  scan the spooling directory and is supposed to be FIFO (First	In First
  Out).	 Filenames comprising a	request	might be unavailable (when lp or lpr
  is used as a sink in a pipeline), in which case the file is indicated	as

       standard	input


  Due to the dynamic nature of the information in the spooling directory, lpq
  might	report unreliably.  Output formatting is sensitive to the line length
  of the terminal and can result in widely spaced columns.


  Appropriate diagnostic messages appear under several conditions:

    +  If there	is no daemon active, but there are files in the	spooling
       directory, the message Warning: no daemon present is displayed.

    +  If the network is unreachable, the message connection to	device is
       down is displayed.

    +  If the printcap file is unavailable, the	message	lpq: device cannot
       open printer description	file is	displayed.

    +  If the spooling directory is unavailable, the message lpq: device can-
       not chdir to spooling directory is displayed.


  To display a request in the print queue, enter:

       lpq -Pprinter1

  This command displays	a list similar to the following:

       Mon March 2 15:15:15 1990: printer1 is ready and	printing

       Rank    Pri   Owner  Job	   Files	      Total Size
       active	0    rcb    888	   massachusetts      1024 bytes
       1st	0    jmp    110	   berkshire	      2048 bytes

  (Output may be formatted differently on your system.)

  An appropriate message is displayed if the lock file is malformed.

      Printer description file.

      Spool directories.

      Daemon control files.

      Data files specified in cf files.

      Temporary	copies of cf files.

      Lock file	used to	obtain the process ID of the current daemon and	the
      request ID of the	currently active request.
