There was another choice like Cygwin, though not as comprehensive - UWin - by David Korn, creator of the Korn shell (ksh): https://en.wikipedia.org/wiki/UWIN https://en.wikipedia.org/wiki/UWIN I've used it some on Windows earlier, and it worked pretty well. Might still available if anyone wants to try it. The only small issue I had was that the process to download it from the (AT&T) web site was slightly involved, for no good reason, as far as I could see. But not difficult.
