You have just been added to a sudo rule on a host and want sudo itself to report which commands you are allowed to run there, without running any of them. Type the complete command.
LPIC-1 Exam 102-500, objective 110. Security 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 answers
sudo -lsudo --listsudo -llsudo -l -l
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
`sudo -l` (long form --list) prints the sudoers rules that apply to the invoking user on the current host, after authenticating you if your timestamp has expired. Repeating the option (`sudo -ll`) prints the same information in a longer, one-rule-per-block format. Root, or a user with the appropriate privilege, can inspect somebody else's rights with `sudo -l -U alice`. Two related no-command forms: `sudo -v` refreshes the authentication timestamp without running anything, and `sudo -k` invalidates it so the next sudo prompts again.
