For some reason - I don't know why - many Windows experts think that command lines are old-hat and should be disposed of forthwith.
Rumours have been rife for years that the command line will disappear from Windows - there were even rumours that Windows XP would come without a command line interpreter.
This onslaught against the command line is odd. The command line forms a very useful way of interacting with a computer, without having to develop a complex GUI, and often providing functionality that would be difficult or clumsy within a GUI. For example, finding all of the files in a command line with filenames containing 'start'. It's not impossible to do it within a GUI, but often the GUI designers don't make it easy.
