Installed Cygwin a few years ago for things like
git and basically anything that works well in the bash commandline. installed the Bash on Ubuntu on Windows 10 program recently and it's basically a Linux distro operating on top of windows 10. It does everything that I used to use Cygwin for.
Maybe I don't know Cygwin well enough, but at the moment I don't see any reason to keep it installed on my system. Does Cygwin have any advantages over Bash on Ubuntu on Windows?
