Windows Server 2012 is a command-line first, GUI-second style of operating system. Indeed, the Server Core installation option is the preferred way of operating with this new version.
As you might expect, that means a significant increase in the surface area of the OS that PowerShell, Microsoft's command-style scripting environment, can manage. Indeed, a simple count as shown in this slide shows 1,317 cmdlets installed out of the box.
As long as WinRM, the remote management framework, is installed and any host-based firewalls are configured correctly, you can use PowerShell to do anything on remote servers -- Unix style, like SSH and bash. Finally, good command-line management of servers locally and remotely has arrived in Windows.
