For some scripting logic, it will prove necessary to break out of the loop. You might imagine that, in one of your scripts, you are waiting for something to finish. As soon as that happens, you want to do something. Waiting and periodically checking inside a while true loop could be an option for this, but if you recall in the while-interactive.sh script, we exited on the successful answer to the riddle. On an exit, we cannot run any more commands that are outside of the while loop! This is where break comes into play. It allows us to exit the loop, but continue the script. First, let's update while-interactive.sh to make use of this loop control keyword:
