enable up key from keyboard to get last entered command during my script

[jcor]

Hi, I have a script that ask several information to users and stores it in vars.

I was wondering if it's possible to get the last information inserted by pressing the "up" key as we do in "normal" shell, while not running any script.

Did I make my self clear?

Does anyone know how to do this?

thanks,

João

First off have you attempted this your self?

second there is a way i know of that you can get it but please attempt doing this your self then we will help you,

also it depends on the OS you are running from what i think you are using try:

history | less

the history command in *nix.

also posting your script may help users understand what you want.
