First I agree that bash scripts should only be used for quick or small (& ultimately mostly personal unshared) tasks. There's absolutely no need for it to be either "dirty", & as mentioned in my post, brevity has no material benefit in this context.

I want my personal local utility/productivity scripts to be readable: quick to write & quick to modify on the fly. Brevity doesn't help here - wpm optimises for natural language typing & that translates better to idiomatic logical block structures than to symbol-heavy one-liners.

I also want the same for the small bash snippets in my CI jobs - this is a particular example where brevity is actively bad: this encourages folk to inline their bash snippets in yaml (no syntax highlighting & unlintable) when they should be packaged in script files in CI directories.
