Wait... Most of my shell scripts have zero unused variables: I prefer to comment them if I may need them later on.

Why do you disable SC2034?

I don't think not having unused variables prevent me from doing things in my scripts!?

I understand if it's a preference but SC2034 is basically one of my biggest timesavers: in my case unused variables are typically a bug. Except, maybe, ANSI coloring variables at the top of the script.

It depends too on whether you use shellcheck as a primary tool or not. I prefer to have no shellcheck errors/warnings by default so when they do appear it's very obvious. But having a consistent opening block on a bunch of scripts is often more important, so setting a shellcheck disable on that one variable that may or may not be used is a better solution.

I disable it only for the DIR variable which I might not use.
