    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
         indicates 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 depen-
         dent 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 mal-
         formed.  Garbage files when there is no daemon active, but
         files in the spooling directory.
