Running linux software on Windows would be convenient if it were seamless. Turns out it is, via the workaround of installing a miniature Linux distro supported by Windows APIs.
There are two flavours, WSL1 and WSL2, which have different technology, the distinction between which has been written about in various places, and I am hoping I do not need to care about.
tl;dr; everyone is using WSL2 now. We have always been at war with WSL1.
Classic install procedures (although really, just google this):
After installing an Ubuntu distro I have an
ubuntu.exe command. Cute!
But slightly confusing.
wsl command can launch many different distros, and even launch into particular apps.
This one is a favourite of mine.:
