I generally agree with your sentiment here, but be careful with assuming bash==bash

There are differences between versions. I can't even remember what they are off the top of my head like I used to, which makes them all the more aggravating to discover again.

But I would recommend sticking to a subset of bash, not any of the new fancy features like 'globstar' which allows recursively globbing.

There are tools to manage these kinds of tests, like bashenv. But you're in the same problem scope at that point.

I much agree with the sister comment and I write my shells for /bin/sh also. There is this wonderful tool called ShellCheck ( https://www.shellcheck.net/ ) that checks that your script is actually POSIX-compliant if it starts with #!/bin/sh

That's why I said "Posix shell" and not bash.
