[Uh-Nu-Buh]

You can use Emacs for most things, but yeah--for many regular shell functions you have to "shell out". I was just kidding around a bit.

Although I did set emacs as my shell for a day (back in '92 I think) to see how well it would work. The next day I went back to bash. ;-)

I'm guessing Gandalf likes bash or tcsh and uses screen as a multi-desktop task-switcher. I used to do that, but I have to admit I have been spoiled by GUIs. First the mac, then xwindows, now I use Gnome for the most part. If I had to link in to my servers on a low-bandwidth connection, I would definitely still use screen+bash (or maybe a compressed vnc).
