lpq - display the content of a print queue
/usr/ucb/lpq [-P destination] [-l] [+ [interval]]
[request-ID...] [user]...
The lpq utility displays the information about the contents of a print
queue. A print queue is comprised of print requests that are waiting in the
process of being printed.
lpq displays the following information to the standard
output:
- o
- the username of the person associated with a print request,
- o
- the position of a print request in the print queue,
- o
- the name of file or files comprising a print request,
- o
- the job number of a print request, and
- o
- the size of the file requested by a print request. File size is reported
in bytes.
Normally, only as much information as will fit on one line is
displayed. If the name of the input file associated with a print request is
not available, the input file field indicates the standard input.
The print client commands locate destination information using the
printers database in the name service switch. See
nsswitch.conf(5), printers(5), and printers.conf(5) for
details.
The following options are supported:
-l
Displays information in long format. Long format includes
the name of the host from which a print request originated in the
display.
-P destination
Displays information about printer or class of printers
(see
lpadmin(8))
. Specify
destination using atomic,
URI-style (
scheme://endpoint), or POSIX-style
(
server:destination) names. See
printers.conf(5)
for information regarding destination names.
+ [interval]
Displays information at specific time intervals. Stops
displaying information when the print queue is empty. Clears the screen before
reporting displaying the print queue. Specify interval as the number of
seconds between displays. If interval is not specified only executes
once.
The following operands are supported:
request-ID
