As the other person said, if your scripts are executables with an sh or bash 'shebang' at the top, they will continue to use the same shell they always did.

But if you did want to run them with zsh, most simple scripts that just set environment variables, string together commands, or redirect to files should work without any changes. The most obvious difference for basic scripts like that is that zsh doesn't split parameter-expansions on white space by default (so if you did something like `opts='-a -b -c'; mycmd $opts` it wouldn't work without additional, minor, modifications)

The minor modification would be from `$opts` to `$=opts`.

I'd been using ZSH for a year as if it was Bash with better history and much better completions. The difference mentioned above was the only one I knew about. I kept writing my scripts in Bash and was quite happy with the UX.

Cool! I do use shebangs, but my concern is that moving forward bash may not be ported to macOS. (Or will I probably be able to, worst case, compile it myself?)
