It should be said that many of the worst footguns shellcheck warns about simply don't apply to zsh – you don't need shellcheck to the same degree that you do with POSIX sh or bash. The first "wrong" example in this article for example (cp $i /tmp) is perfectly fine in zsh, and the complex 'mv "$i" "$(suf "$i")".jpg' is just 'mv $i $i:r.jpg' in zsh. $* and $@ are identical in zsh, and both are also arrays. There is no way to use it wrong really, and no weird '"$@" with quotes is a special case that's handled different from everything else'. Most "shell problems" people experience are "bash problems" (or "POSIX sh problems", but for many they're more or less synonymous); certainly pretty much all the problems listed in this article are. This always proves to be a controversial opinion, but I will forever keep insisting: just don't use POSIX sh or bash if it can at all be helped. You most likely don't need the portability, and installing zsh (or fish, or oil, or whatever) is easy enough in most the cases because you're the one controlling the environment.
