lpq - Examines the spool queues.
lpq [+] [number] [-l] [-Pprinter] [request-ID...] [user...]
-l Displays information about each of the files comprising the printer
Specifying printer displays requests queued for that printer only.
Displays the spool queue until it empties. Sleeps number seconds
between scans of the queue if number is specified.
The lpq command examines the spooling area used by lpd for printing files
on the line printer and reports the status of the specified requests or all
requests associated with a user.
The lpq command invoked without any arguments reports on any requests
currently in the queue. The -P option can be used to specify a particular
printer; otherwise, the default line printer is used (or the value of the
PRINTER environment variable).
Specifying one or more request-IDs displays only the specified requests.
Specifying one or more users displays print requests from those users only.
If you specify the + argument, lpq displays the spool queue until it
empties. Supplying a number immediately after the + argument indicates
that lpq should sleep number seconds in between scans of the queue. All
other arguments supplied are interpreted as user or request-ID arguments to
display only those requests of interest.
For each request submitted (that is, each request invoked by lp or lpr),
lpq reports the user's name, current rank in the queue, the names of files
comprising the request, the request ID (a number that you can use to
identify the request to other commands, such as lprm) and the total size of
the job in bytes.
The -l option causes information about each of the files comprising the
request to be displayed; without it, only as much information as will fit
on one line is displayed. Job ordering depends on the algorithm used to
scan the spooling directory and is supposed to be FIFO (First In First
Out). Filenames comprising a request might be unavailable (when lp or lpr
is used as a sink in a pipeline), in which case the file is indicated as
Due to the dynamic nature of the information in the spooling directory, lpq
might report unreliably. Output formatting is sensitive to the line length
of the terminal and can result in widely spaced columns.
Appropriate diagnostic messages appear under several conditions:
· If there is no daemon active, but there are files in the spooling
directory, the message Warning: no daemon present is displayed.
· If the network is unreachable, the message connection to device is
down is displayed.
· If the printcap file is unavailable, the message lpq: device cannot
open printer description file is displayed.
· If the spooling directory is unavailable, the message lpq: device
cannot chdir to spooling directory is displayed.
