While mindlessly browsing I wondered how many DOS commands have been registered as a domain name. A couple of them (with a brief description taken from the help):
More.com (displays output to the screen one at a time), format.com (formats drives), win.com [available] (loads Windows from DOS), Edit.com (Remember? That was just the *QB* editor), diskcopy.com [not worth linking] (copies disks without forcing the users to play diskjockey) and the best of all: command.com.
That blinking cursor looks inviting, doesn’t it?
