[Nottingham] Bash Variables

[Mike Haber]

Hi Martin,
 
> What is it that you're trying to do?
It was really after the event. A script was run that modified a
variable, and we wondered if bash kept the previous values tucked away
someplace safe. 
With the massive amount of features bash has, I thought that it just
*might* do that.

I think he'll save them somewhere safe.

Thanks
Mike
