lpq
— spool queue
examination program
lpq |

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.
The options are as follows:
-a
-l
-P
printerPRINTER
variable in the
environment). All other arguments supplied are interpreted as user names
or job numbers to filter out only those jobs of interest.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.
If the following environment variables exist, they are used by
lpq
:
Unable to open various files. The lock file being malformed. Garbage files when there is no daemon active, but files in the spooling directory.
lpq
appeared in
3BSD.
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 result
in widely spaced columns.
