Windows has also always come with a command line. In really old versions of windows you invoked it by running command.com. Last 10 odd years, you invoke it by running cmd.exe. It’s not as powerful as the unix shell, but you can get a lot of things done on it & with cscript, it becomes quite powerful. And for the last 5 odd years, you also have Powershell on windows which is as good as any command line.
PowerShell is an extremely powerful CLI. Windows Server 2012 (or whatever they end up calling it) is managed entirely through PS. Even the GUI is just an interface to PS. That means you can manage a WinSrv 2012 machine from any other machine, of any flavor. Looks like MS is finally playing major league ball, and playing it well.
