An old script prints with `lpr -P accounts report.ps`. You are rewriting it to use the System V command lp instead. Which option of lp names the destination?
LPIC-1 Exam 102-500, objective 108. Essential system services easy
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
The options
Correct -d
Correct. lp -d destination selects the printer or class the job goes to, which is what -P does for lpr.
Not correct -P
Wrong. -P is the BSD spelling used by lpr, lpq and lprm. On lp, -P instead selects which pages of the document to print, for example -P 1-4.
Not correct -o
Wrong. -o passes job options such as sides=two-sided-long-edge or media=A4 through to the destination. It configures how the job prints, not where.
Not correct -n
Wrong. On lp, -n sets the number of copies. The lpr equivalent for copies is -#.
Why
The two command families use different letters for the same ideas, and the exam tests them directly: destination is -d on lp and -P on lpr, copies are -n on lp and -# on lpr. Both submit through the same CUPS scheduler, so a job sent either way appears in the same queue. Both read from standard input when given no file argument, which is what makes them usable at the end of a pipeline.
