Question 8. CSCD240-E1-A
What does 4096 refer to in the ls -l line?
Work the drill
Answer on paper or in a terminal before revealing the ideal answer.
Ideal answer
File size in bytes.
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.
Inode number
Misconception. Common confusion; inode is not shown by default ls -l.
Remedy. Show stat vs ls -l side-by-side to distinguish fields.
Block size
Misconception. Blocks are usually shown as 4KB units but this is the byte count.
Remedy. Clarify: ls -l size is in bytes; ls -lh shows human-readable. Block count = ls -s.
