Uh, MacOS has zsh (which has far more features than most other POSIX shells), and even old bash has POSIX compatibility.

Your TV/IoT device likely has busybox, as does your router.

You install git on windows, it's got a (POSIX) shell.

The number of places that lack a shell is tiny.

Node/deno/bun are rare, and browsers whilst being more common, still require the device to have some kind of GUI.

I don't think it's in the path by default so if some program like npm calls exec("rm") it's still going to fail I think.


Read my comment on macOS please - it explicitly is about dealing with Linux people who write scripts assuming new versions of Bash.

Now if Linux used zsh then your comment is valid.

Bash shell scripts do not necessarily run in zsh.

Most Windows users do not install git. iPhones don't have a shell.


Assuming `/bin/sh` is bash is going to break on a whole bunch of systems (not just MacOS), and zsh implements POSIX. Also, this is for bun, so I'd be concerned that you're missing git on Windows.
