NAME
lprq - spool queue examination program
SYNOPSIS
lprq [-l] [-Pprinter] [job # ...] [user ...]
DESCRIPTION
Lprq 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. Lprq 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.
For each job submitted (i.e. invocation of lpr(1)) lprq 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 lprrm(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 lprq warns that there is no daemon present (i.e. due to some malfunction), the lprc(8) command can be used to restart the printer daemon.
ENVIRONMENT
If the following environment variable exists, it is used by lprrq:
PRINTER Specifies an alternate default printer.
FILES
- /etc/printcap
- To determine printer characteristics.
SEE ALSO
lpr(1), lprrm(1), lprc(8), lpd(8)
HISTORY
Lprq appeared in 3BSD.
BUGS
Due to the dynamic nature of the information in the spooling directory lprq may report unreliably. Output formatting is sensitive to the line length of the terminal; this can results in widely spaced columns.
DIAGNOSTICS
Unable to open various files. The lock file being malformed. Garbage files when there is no daemon active, but files in the spooling directory.
