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.
A: ps
Misconception. Default ps shows only current terminal processes.
Remedy. Flag table: -e/-A = all, aux = BSD all, -f = full format.
B: ps -ef
Misconception. -ef is System V style, not BSD; question asks BSD.
Remedy. Accept as equivalent in practice but tests style awareness.
D: jobs
Misconception. jobs is shell-local, not system-wide.
Remedy. jobs ≠ ps.
