A useful thing with conditionals is shellcheck will warn you not to write [ foo -eq 1 && bar -eq 2 ], but to write [ foo -eq 1 ] && [ bar -eq 2 ] or [[ foo -eq 1 && bar -eq 2 ]]. I do think it would be nice if shellcheck was more opinionated, or if it was possible to create rulesets that have stronger opinions. For example, I would personally like to enforce the use of double bracket conditionals in my scripts, but I know that others prefer the single bracket variety.
