Work the drill

Same thing, different syntax

Misconception. Misses depth/scope difference.

Remedy. Show man ls vs ls --help side-by-side — one is pages, one is lines.

man is for developers, --help for users

Misconception. Inaccurate distinction.

Remedy. Both tools are for anyone; scope differs (thorough vs quick).
