Is this "Learn the command Line" valid even for Windows? If yes, does this teach how to deal with cmd.exe?


Not really.

You might prefer to use PowerShell over cmd.exe

The track uses Ubuntu (a gnu/linux distro) but applies to all unix-like systems (unix, solaris, bsd, mac, gnu/linux, others)

Windows is aimed more at point-and-click, so if you're after a command-line interface then linux may be preferable. Any major linux distro will do, they use mostly the same things, varying mainly in how fast they are updated.

That said I'm sure you can get things done in Windows as well.


Basically what @ionatan said is no, it is not for Windows but it works on a variety of other things.
