Devraj B.Jun 9, 2026C is your answer, and this one maps directly to LPI 102-400 objective 105.1, which carries a weight of 4, so expect it to show up more than once on test day. The noclobber option tells bash to refuse a redirect that would overwrite an existing file, meaning if you try to send output to a file that already exists using a plain greater-than redirect, the shell throws an error instead of silently destroying your data. Options A, D, and E do not exist as valid bash set options, so they are pure distractors. Option B, noglob, disables pathname expansion for wildcards and has nothing to do with file overwriting. Your memory hook here is to think "no clobber, no stomp," because clobber is an old Unix term for trashing a file by overwriting it, and this option puts a lock on that behavior.
Thiago A.Jun 16, 2026C, set -o noclobber, saw it word for word on my 102 sitting last year, nearly second-guessed myself toward E until I remembered noclobber is what the man bash page actually calls it.
Devraj B.Jun 18, 2026Solid recall on noclobber, and worth adding that set -o noclobber maps directly to LPI 103.4 redirection objectives, so if you see a question about preventing overwrite of existing files with >, that option name is the only one that will ever appear on the exam.
