So you have the newest, glitziest, "Fisher Price" version of Windows: XP. How
can you use XP in a way that sets you apart from the boring millions of ordinary
users?

The key to doing amazing things with XP is as simple as D O S. Yes, that's
right, DOS as in MS-DOS, as in MicroSoft Disk Operating System. Windows XP (as
well as NT and 2000) comes with two versions of DOS. Command.com is an old DOS
version. Various versions of command.com come with Windows 95, 98, SE, ME,
Window 3, and DOS only operating systems.

The other DOS, which comes only with XP, 2000 and NT, is cmd.exe. Usually
cmd.exe is better than command.com because it is easier to use, has more
commands, and in some ways resembles the bash shell in Linux and other Unix-type
operating systems. For example, you can repeat a command by using the up arrow
until you back up to the desired command. Unlike bash, however, your DOS command
history is erased whenever you shut down cmd.exe. The reason XP has both
versions of DOS is that sometimes a program that won?t run right in cmd.exe will
work in command.com

note : m not comparing bash to dos


DOS is your number one Windows gateway to the Internet, and the open sesame to
local area networks. From DOS, without needing to download a single hacker
program, you can do amazingly sophisticated explorations and even break into
poorly defended computers.
