LPQ(1N) UNIX 5.0 (September 29, 1988) LPQ(1N)
NAME
lpq - spool queue examination program
SYNOPSIS
lpq [ -l ] [ -Pprinter ] [ job # ... ] [ user ... ]
DESCRIPTION
lpq examines the spooling area used by lpd(1M) 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). 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(1N)) 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(1N) 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(1N)
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(1M) 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(1N), lprm(1N), lpc(1M), lpd(1M)
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.

LPQ(1N) UNIX 5.0 (September 29, 1988) LPQ(1N)
Unable to open various files. The lock file being
malformed. Garbage files when there is no daemon active,
but files in the spooling directory.
