This post is nice: the writer first explains a problem, using a simple example. In the next section, they reflect a bit about the problem, and then they casually mention two tools they built. In my opinion, this is amazing: you sponsor you project, while also making the problem it solves clear: use their tool to test how portable your code is

If your environment is POSIX, testing scripts with tool written in POSIX shell, like shellspec[1], might also be a choice.

Pretty bad argument. If it’s not defined by POSIX, it’s not POSIX compatible if you rely on a specific behavior.

If you only use defined behavior and it works, it is compatible.

It’s like saying C99 isn’t a compiler. True, but you can still write C99 code, right?

Sure, but the pojt here is that if we say "Write in X" we generally understand it to mean "Treat X like a standard and don't get too colloquial with the stylings."

Pedantry is worthwhile, but it can be a diminishing returns game.

Will not build without docker, so I am out of luck. This tells me this is not portable, even to some Linuxes.
