up-arrow history recall ksh

Kornshell used ESC-K for up arrow. That, of couurse, matched well with vi's use of the h-j-k-l keys and also many terminals used variations (contol-k, ESC-{-K) for their arrow keys, so that was a reasonable choice.

Well, reasonable assuming you wanted to hard code rather than use Termcap/Terminfo as it should have been done!

Before switching to bash, I just got used to ESC-K. I worked on too many different systems; that was easier.

The stock ksh has this ability, with a little work.  In your .profile:

    ENV=~/.kshrc

In your .kshrc:

    set -o emacs
    alias __A="^P"
    alias __B="^N"
    alias __C="^F"
    alias __D="^B"
    alias __H="^H"
    alias __P="^P"

Note that those are real control characters, and not literal ^Fs or whatever.
This is only good for ANSI compatible terminals, but unless you're using 
really old terminals that's unlikely to be a problem.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
