It is not fashionable nowadays to speak of the merits of the command line, in an age where things like streaming video and Aqua are an integral part of our daily life. However, I do not think that typed-in commands must necessarily be consigned to the dustbin of computer history. Of course, I am not suggesting that we all drop X and Windows and pretend like we are living in the early eighties. The command line interface still has much to offer us, and many of its benefits simply cannot physically be emulated or even replaced by graphical ones.
To prove my point:
M$ has creted a network scan tool to see which hosts have crippy RPC implementations (unpatched). You need the RPC patch to protect your Windows machine against the Blaster virus.
The tools uses a command line interface. It's a console app.

The CLI is far from dead. It's even USEFUL BECAUSE NORMAL USERS DON'T UNDERSTAND IT, so they will not touch tools only meant for sysadmins.
