> portable and reliable to use across Debian, Arch or RHEL based distributions Until you try to use a newer feature or try the script in a Mac or BSD or any older bash. SH code is completely portable, but bash itself can have quite a few novel features. Don’t get me wrong - I’m happy the language is dynamic and still growing. But it can make things awkward when trying to use a script from a newer system on an older server (and the author has been “clever”).
