LPQ(1) BSD General Commands Manual LPQ(1)
lpq -- spool queue examination program
lpq [-al] [-P printer] [-w maxwait] [job# ...] [user ...]
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.
-P 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.
-l Information about each of the files comprising the job entry is printed. Normally,
only as much information as will fit on one line is displayed.
-a Report on the local queues for all printers, rather than just the specified printer.
Specify the maximum time to wait in seconds for remote responses. The default is
300 seconds or 5 minutes.
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. 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
If lpq warns that there is no daemon present (i.e. due to some malfunction), the lpc(8) com-
mand can be used to restart the printer daemon.
If the following environment variable exists, it is used by lpq:
PRINTER Specifies an alternative default printer.
/etc/printcap To determine printer characteristics.
/var/spool/output/* The spooling directory, as determined from printcap.
/var/spool/output/*/cf* Control files specifying jobs.
/var/spool/output/*/lock The lock file to obtain the currently active job.
Unable to open various files. The lock file being malformed. Garbage files when there is
no daemon active, but files in the spooling directory.
lpr(1), lprm(1), lpc(8), lpd(8)
lpq appeared in 3BSD.
Due to the dynamic nature of the information in the spooling directory lpq may report unre-
liably. Output formatting is sensitive to the line length of the terminal; this can results
in widely spaced columns.
