Preserving values with for loop for later use

This is a unix shell script related question. But posting it here since there is no seperate section for Shell scripts.

Below is the issue I am having.

I have a few variables which have certain values in them like
var1=23
var2=46
var3=78 etc...


I want to save these values with the help of a for loop in a single variable so that I can use it later,beacuse a few lines down the script, some of these variables get set to a different value and I would like to reset them to the values that I had saved.Can you point out a way without using arrays?

Hi, recent versions of bash have one-dimensional arrays, e.g.:



To dereference your values, you'll need curlies around the name of the variable:



With other shells, I don't think it is possible, except perhaps by simulating it using symbolic references.
