Your welcome, took me a few hours to find an example I could actually get working with what I was attempting to achieve. Glad it also helpded someone else out.

Original thread where I got the example from:
https://www.unix.com/shell-programmin...namically.html

I dont know why I didnt think to us the i variable instead of comparing strings. Probably just tired. Thanks to everyone for the input. I have learned alot this week.

I did change to i variable instead of comparing strings as it made more sense, however for some reason ((i++)) did not work so I reverted that piece back to the way I had it.

Code:
# bash and ksh
((i+=1))
# posix standard = works also bash and ksh
i=$(($i + 1 ))
