|Haha, greatness can be in little things. Of course, it doesn't work on the old DOS, since you need a window to have a title ... ;)|
Razor; particularly stuff like WC, ... even PS is still not a standard DOS command ?! Let me think what else. Euhm, KILL ? Or a command to reboot your computer ... And what about DU ? And DF, handy as well. And did I mention LN ? I'm sure I forgot some ... but it's not just commands, it's also the set of features included in commands.
Take IF for example, now you can do an ELSE (since XP ?); but the IF command on unix/linux is still much better : ELSE, ELSIF
I'll not mention AWK, since that is a special case, but I use it a lot, and there's nothing standard on DOS ...
OK, there ya go. I'm sure that one of the above has got a DOS replacement ... if you know one, please mention. Of course, I mean STANDARD commands!
edit: And some more : TOP (how could I forgot that one), TAIL (TAIL -F !!!), HEAD, TAR, ZIP, BASENAME, DIRNAME
