How to change last character in string with a variable value.
Hey Guys,

I have text such as this.
Code:
28003,ALCORN,2
28009,BENTON,2
28013,CALHOUN,2
28017,CHICKASAW,2
47017,CARROLL,2
05021,CLAY,0


The last digit after the final "," is a variable value. This is the base file. I have to do further execution on this file later and I need to update the 3rd value at that time. So, How do I open this file, and append the last digit to my new variable, and also save as the same filename. I have tried multiple unsuccessful options.

An example of what I want is essentially the same output only with the new variable values appended. Using shell by the way.
