Which of the following commands lists all queued print jobs?

Question

Options

• Alpd
• Blpr
• Clp
• Dlsq
• Elpq

• A
  9% (2)
• B
  4% (1)
• C
  13% (3)
• E
  74% (17)

Explanation

lpq (option E) is correct - the "q" stands for queue, and this command displays the status of the print queue, showing all pending, active, and completed print jobs along with their job IDs and owner.

• A. lpd - the line printer daemon, a background service that manages printing; it doesn't list jobs.
• B. lpr - used to submit a print job, not view the queue.
• C. lp - also submits print jobs (the System V equivalent of lpr); not for listing.
• D. lsq - not a standard Unix/Linux print command; it doesn't exist in this context.

Memory tip: Think of lpq as "line printer query" - you're querying what's in the queue, just like ls lists files. The pattern holds: lpr = remove a job's counterpart is lprm, and lpq = query the queue.
