The overwhelming majority of UNIX-like software isn't designed for BSD runtimes, to name one.
The overwhelming majority of UNIX-like software is available in the package managers right now for major BSDs.
I ask for a specific example, and you respond with more generalities.
Aside from the BSD software, the Mac software, and all the software that’s actually POSIX-compliant (on purpose or by accident).
So exactly eves “Unix like software” will kids be missing that prevents them from learning about computers?
