Question 40. CSCD240-E1-C
sort /var/log/audit.log > /var/log/audit.log — state and why.
Work the drill
Answer on paper or in a terminal before revealing the ideal answer.
Ideal answer
audit.log becomes empty. Shell truncates target BEFORE sort reads source.
Misconception bank
Each row below is a plausible wrong answer, the thinking that produces it, and the remedy that corrects the misconception. These are the foundation of the multiple-choice framing and the targeted feedback a student receives after answering.
File is sorted in place
Misconception. Missing truncate-first rule.
Remedy. Use sort -o for in-place.
