change up arrow behavior with bash history

Well I can definitely relate to "vi culture shock". I've tried it a couple of times, but never had the patience to actually learn it. Usually I'm a fan of shortcuts, but I guess I'm happy enough with kedit or something...

You need two hands to type a single character (/)?

'&' is also a single character, don't you need two keys for that one on the english keyboard? On the norwegian keyboard you press shift-7 to get '/'.

Wait to have a system crash and no more xwindow, you will realize how practical vi is

Same on a german keyboard.

Point taken on the &. I did allow for the possibility other keyboards wouldn't make a / natively. Only God knows what I'd have to do to type "ø".

I know, I know... Luckily it hasn't happened very often so far

I think in a system crash the least of my worries will be which editor I'm using.

Well, with no Xwindow, the choice is easily done

Indeed; emacs works perfectly without X.

Sometimes, rather than use vi, I've edited files with sed or awk.

(If anyone is familiar with the command line interface in Matlab, that's the behavior I'm looking for).

Is this already implement somewhere, or can I make my own script somehow?

Cheers

Put the following in ~/.inputrc:

"\e[A": history-search-backward ## up-arrow
"\e[B": history-search-forward ## down-arrow

Check that those are the correct key sequences for your terminal by pressing Ctrl-v then an arrow key.

I love these people who repeat exactly stuff that's already been said...
