NAME
lpq - spool queue examination program
SYNOPSIS
lpq [ +[ n ] ] [ -l ] [ -Pprinter ] [ job # ... ] [ user ... ]
DESCRIPTION
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. A -P flag may be used to specify a particular printer, otherwise the default line printer is used (or the value of the PRINTER variable in the environment). If a + argument is supplied, lpq displays the spool queue until it empties. Supplying a number immediately after the + sign indicates that lpq should sleep n seconds in between scans of the queue. 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. The -l option causes information about each of the files com- prising the job to be printed. Normally, only as much information as will fit on one line is displayed. 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.
FILES
/etc/termcap for manipulating the screen for repeated display /etc/printcap to determine printer characteristics /usr/spool/* the spooling directory, as determined from printcap /usr/spool/*/cf* control files specifying jobs /usr/spool/*/lock the lock file to obtain the currently active job
SEE ALSO
lpr(1), lprm(1), lpc(8), lpd(8)
BUGS
Due to the dynamic nature of the information in the spooling directory lpq may report unreliably. Output for- matting 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. 4.2 Berkeley Distribution June 5, 1986 LPQ(1)
