Just out of curiosity, why:
Code:
count=$(echo -n ${#count})

instead of:
Code:
count=${#count}

The echo is not needed, and the -n option to echo (which isn't needed for this example even if you use echo) won't do what you want on most UNIX systems.

I live and learn. Thanks for correcting me.
I chose the echo method because I knew it worked and why. I did not know about your shortened version. That is now logged in the _old_ grey matter. ;o)
As for the "-n" I was thinking I was creating a file, my error. I will leave my post as is as you have already pointed it out and shown a better alternative anyhow...

However my variable(s) point still holds true...

Thanks a lot...
