I want to get my up arrow key to recall my previous commands in Korn shell.
Anyone help please?

thanks a bunch!

add the following
lines to the bottom of your .kshrc file in your $HOME directory:

set -o emacs
alias __A=$(print '\0020') # ^P = up = previous command
alias __B=$(print '\0016') # ^N = down = next command
alias __C=$(print '\0006') # ^F = right = forward a character
alias __D=$(print '\0002') # ^B = left = back a character
alias __H=$(print '\0001') # ^A = home = beginning of line

I like vi as my editor.

can i do this with vi?

This doesn't change your editor, it puts ksh into emacs mode. And no you can't do this with ksh in vi mode.
