LPQ(1) BSD General Commands Manual LPQ(1)
NAME
lpq -- spool queue examination program
SYNOPSIS
lpq [-al] [-P printer] [-w maxwait] [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.
Options:
-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.
-w maxwait
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 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.
ENVIRONMENT
If the following environment variable exists, it is used by lpq:
PRINTER Specifies an alternative default printer.
FILES
/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.
DIAGNOSTICS
Unable to open various files. The lock file being malformed. Garbage files when there is no daemon active, but files in the spooling direc-
tory.
SEE ALSO
lpr(1), lprm(1), lpc(8), lpd(8)
HISTORY
lpq appeared in 3BSD.
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.
