A user wants to stop the job that is currently printing on their default destination, without first looking up its job id. Type the System V style CUPS command, with no options or arguments, that does this.
LPIC-1 Exam 102-500, objective 108. Essential system services 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.

Answer
Type the answer.
Accepted answer
cancel
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
CUPS provides two command sets. In the System V set, cancel with no arguments cancels the job currently printing on the default destination, cancel id cancels one named job and cancel -a removes every job. The BSD equivalent is lprm, which behaves the same way when given no job number. Ordinary users may only cancel their own jobs unless the CUPS policy grants them more.
