NAME
       lpq - spool queue examination program

SYNOPSIS
       lpq [ +[ n ] ] [ -l ] [ -Pprinter ] [ 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.  A -P flag may be used
       to specify a particular printer, otherwise the default line printer is used (or the  value
       of  the	PRINTER  variable in the environment).	If a + argument is supplied, lpq displays
       the spool queue until it empties.  Supplying a number immediately after the +  sign  indi-
       cates  that lpq should sleep n seconds in between scans of the queue.  All other arguments
       supplied are interpreted as user names or job numbers to filter out  only  those  jobs  of
       interest.

       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.  The -l option causes information about each of the files comprising the job to  be
       printed.   Normally,  only  as much information as will fit on one line is displayed.  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.

FILES
       /etc/termcap	       for manipulating the screen for repeated display
       /etc/printcap	       to determine printer characteristics
       /usr/spool/*	       the spooling directory, as determined from printcap
       /usr/spool/*/cf*        control files specifying jobs
       /usr/spool/*/lock       the lock file to obtain the currently active job

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

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.

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