Canonical and Microsoft have cooperated so that you can use bash in Windows 10.
Popular stuff like ssh, rsync, find, grep, awk, sed, sort, xargs, md5sum, gpg, curl, wget, apache, mysql, python, perl, ruby, php, gcc, tar, vim, emacs, diff, patch - you name it.
You can put a base on Windows 10 that will run bash and it is called Windows Subsystem for Linux or WSL (I wonder if that will be Open Source).
People have complained about the use of open source on WIndows so they decided to do something about it.
It will be available in June for everybody; until then you can test it by becoming a Windows insider (If you like privacy then that is nothing for you!).
This is big news from Microsoft but it is hard to see how it is different from RedHat's Cygwin at this point.
It looks like Canonical and Microsoft are cooperating with this so the integration might be easier and tighter.
As a package manager you will get Ubuntu's Apt.
The natural question is; why use Linux under Windows when you can use Windows under Linux. As a platform Linux is more stable so that would make more sense.
The future might bring better interop between Linux and Windows which is a good thing.
