| 15 | _\bl_\bp_\bq examines the spooling area used by _\bl_\bp_\bd(8) for printing | |
| 16 | files on the line printer, and reports the status of the | |
| 17 | specified jobs or all jobs associated with a user. _\bl_\bp_\bq | |
| 18 | invoked without any arguments reports on any jobs currently | |
| 19 | in the queue. A -\b-P\bP flag may be used to specify a particular | |
| 20 | printer, otherwise the default line printer is used (or the | |
| 21 | value of the PRINTER variable in the environment). All other | |
| 22 | arguments supplied are interpreted as user names or job | |
| 23 | numbers to filter out only those jobs of interest. | |
| 24 | ||
| 25 | For each job submitted (i.e. invocation of _\bl_\bp_\br(1)) _\bl_\bp_\bq | |
| 26 | reports the user's name, current rank in the queue, the | |
| 27 | names of files comprising the job, the job identifier (a | |
| 28 | number which may be supplied to _\bl_\bp_\br_\bm(1) for removing a | |
| 29 | specific job), and the total size in bytes. The -\b-l\bl option | |
| 30 | causes information about each of the files comprising the | |
| 31 | job to be printed. Normally, only as much information as | |
| 32 | will fit on one line is displayed. Job ordering is depen- | |
| 33 | dent on the algorithm used to scan the spooling directory | |
| 34 | and is supposed to be FIFO (First in First Out). File names | |
| 35 | comprising a job may be unavailable (when _\bl_\bp_\br(1) is used as | |
| 36 | a sink in a pipeline) in which case the file is indicated as | |
| 37 | ``(standard input)". | |
| 38 | ||
| 39 | If _\bl_\bp_\bq warns that there is no daemon present (i.e. due to | |
| 40 | some malfunction), the _\bl_\bp_\bc(8) command can be used to restart | |
| 41 | the printer daemon. | |

| 54 | Due to the dynamic nature of the information in the spooling | |
| 55 | directory lpq may report unreliably. Output formatting is | |
| 56 | sensitive to the line length of the terminal; this can | |
| 57 | results in widely spaced columns. | |
