lpq(1) lpq(1)NAME lpq - spool queue examination program SYNOPSIS lpq [ +[ n ] ] [ -l ] [ -Pprinter ] [ job # ... ] [ user ... ] DESCRIPTION lpq examines the spooling area used by lpd(1M) for printing files on the line printer and reports the status of the specified jobs or all jobs associated with a user. lpq in- voked without any arguments reports on any jobs currently in the queue. For each job submitted (for example, an invocation of lpr(1)) lpq reports the user's name, current rank in the queue, the names of files comprising the job, the job iden- tifier (a number which may be supplied to lprm(1) for remov- ing a specific job), and the total size in bytes. If lpq warns that no daemon is present due to some malfunc- tion, the lpc(1M) command can be used to restart the printer daemon. FLAG OPTIONS The following flag options are interpreted by lpq: -P Specifies a particular printer, otherwise the default line printer is used (or the value of the PRINTER vari- able in the environment). +n 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. -l Prints information about each of the files comprising the job. Normally, only as much information as fits 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). Filenames comprising a job may be unavailable when lpr(1) is used as a sink in a pipeline, in which case the file is in- dicated as ``(standard input)". All other arguments supplied are interpreted as user names or job numbers to filter out only those jobs of interest.

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 result in widely spaced columns. DIAGNOSTICS lpq may report that it is unable to open various files. The lock file may be malformed. Garbage files found in the spooling directory may be printed when no daemon is active. 2 April, 1990
