Getting to the command prompt in Windows 8 is different but the list of commands available is similar to that for Windows 7. Some commands for Windows 8 and a brief explanation of their functions are given. The discussion applies to the Consumer Preview version of Windows 8.
How to open the command prompt in Windows 8
In Windows 8, the command prompt itself looks the same as in previous Windows but getting there is different. The user interface in Windows 8 has been changed substantially. Here is one way to open the command prompt. On the Start screen, click the "Windows Explorer" icon. In the Libraries window that opens, click the "File" menu. The File menu contains an entry "Open command prompt". Placing the mouse there gives a fly-out with the choice of a regular command prompt or one run with administrator privileges. Figure 1 illustrates the menu.

One of the bugs in the beta version seems to be that this entry for the command prompt sometimes gets greyed out. Another route to the command prompt is to place the mouse on the bottom-left corner of the screen and right-click the tile that pops up. The context menu contains an entry both for the regular command line and for the commannd line run as administrator.
Another way to the command prompt will be familiar. Use the keyboard shortcut Winkey+R to open the Run line and then enter "cmd" (without quotes).
Once the command shell is open, it looks pretty similar to previous versions.
