Type the single command, with no options and no arguments, that lists your own pending at jobs.
LPIC-1 Exam 102-500, objective 107. Administrative tasks 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.
Answer
Type the answer.
Accepted answer
atq
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
atq prints one line per queued job: job number, scheduled execution time, queue letter and owner. Run by an unprivileged user it shows only that user's jobs; run by root it shows everyone's. The job number it prints is the handle you pass to atrm to cancel a job or to `at -c` to inspect one.
