LPIC-1 Exam 102-500, objective 107. Administrative tasks medium
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 answers
crontab -u bob -lcrontab -l -u bob
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
-u names the crontab to act on and may be combined with -l, -e or -r. Only root may use -u; an ordinary user always acts on their own crontab. Note that -u affects only per-user crontabs, so it will not show jobs bob's account runs from /etc/crontab or /etc/cron.d, which have to be inspected as files.
