I've always been the kind of guy who loves using command prompts. I guess that is partly a reason why I got deep into *nix back in college. No windows, just a trusty command prompt. That carried into how I worked in Windows. I still to this day add a shortcut to the command prompt in the quick start area because I love using them.
I realize that this post will fall on deaf ears for the most part, I belive I am in the minority when it comes to my love for using command prompts. However, maybe those who don't use command prompts don't realize how productive they can be, or maybe they've just never used them or know the commands to get things done? Never fear. If you're running XP or 2003 go to the Run dialog and enter hh ntcmds.chm. You'll get a help file with all the command prompts you'd ever need to know. An awesome resource for those who are command-challenged or even those who regularly use command prompts. I came accross this a long while ago but had forgotten all about it until I read a post that reminded me.
On the subject of command prompts, did you know that there is a difference between command.com and the cmd.exe? Big one too. Ian Griffith does a great explanation of this. Well worth the read.
