LPQ(1)LPQ(1)NAMElpq - spool queue examination program
SYNOPSISlpq [ +[ n ] ] [ -l ] [ -Pprinter ] [ job # ... ] [ user ... ]
DESCRIPTION
The lpq utility 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. If lpq is invoked without any
arguments it 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. Note the default line printer cannot be specified as
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 comprising 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, and will be
indicated as ``(standard input)''. Unavailable file names can occur
when lpr(1) is used as a sink in a pipeline.
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 - if NetInfo is
not running.
/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 ALSOlpr(1), lprm(1), lpc(8), lpd(8), netinfo(5)BUGS
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 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.
