lpq - Examines the spool queues.
lpq [+] [number] [-l] [-Pprinter] [request-ID...] [user...]
Displays information about each of the files comprising the
queued for that printer only.
Displays the spool queue until it empties. Sleeps
seconds between scans of the queue if
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 follows:
Due to the dynamic nature of the information in the spooling directory,
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
If the network is unreachable, the message
If the printcap file is unavailable, the message
cannot open printer
If the spooling directory is unavailable, the message
cannot chdir to
To display a request in the print queue, enter: lpq -Pprinter1
