there's absolutely nothing wrong with the functionality (it's essential in fact), it's that maybe, maybe, we should purge shell scripts from our hearts. (or at least reserve them for ad-hoc one-off in-situ time-conscious pragmatic programs, instead of letting a billion bash-lines beat its little shell-song behind every .deb,.rpm & etc.)

// and of course 'should' is more like "it would be great if someone would rewrite it in Rust"
