lpq - BSD print spool queue examination program
SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
llllppppqqqq [ -l ] [ -Pprinter ] [ job # ... ] [ user ... ]
DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
_l_p_q examines the spooling area used by _l_p_d(1M) for printing files on the
line printer, and reports the status of the specified jobs or all jobs
associated with a user. _l_p_q invoked without any arguments reports on any
jobs currently in the queue. A ----PPPP 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 _l_p_r(1)) _l_p_q 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 _l_p_r_m(1) for
removing a specific job), and the total size in bytes. The ----llll 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 _l_p_r(1) is used as a sink
in a pipeline) in which case the file is indicated as ``(standard
input)".
If _l_p_q warns that there is no daemon present (i.e. due to some
malfunction), the _l_p_c(1M) command can be used to restart the printer
daemon.

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.

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