You changed the script to execute tcpreplay via ./tcpreplay .... Hence you need to change the jobs line to also read ./tcpreplay
As for the stats, you probably could hack the code to print them easily enough after the kill / CTRL-C. I could do it too, but it'd be a day or two before I had time to look into it. You could also just use the 'time' command with say 100 loops and see how long it takes. Then the math would be pretty simple to figure out how many loops you need it to run for 10 seconds.
