What is it that you think set -v actually does? What's your goal in
using it?
I've used -v before on simple test scripts and under simple conditions I got what I was expecting. -v in a more demanding environment such as the case statement is useless - I agree.
I thought it was going to echo the lines of code as they were being executed, much like -x only without all the -x hieroglyphics. I was hoping to use both simultaneously to read a line of code via -v and then see the -x version along side. That would be handy. As it is, -v is not usable for anything of any consequence.
I tried reading up on the debugger and got lost. I guess I'll give it a try again as I want something that can single step, display intermediate results, etc without resorting to echo this and echo that at the source code level. I thought -v might provide some relief, but no such luck.
