Work the Shell - End Game
There's also one outstanding bug in the code, and I invite you to dig around and figure it out. If the dealer is dealt an Ace in play, it's automatically counted as 11 points, not one or 11, as it should be. Your challenge: figure out where that problem arises and how to fix it. If you think you know, e-mail me your proposed solution (perhaps a diff of your version versus the version on the Linux Journal FTP site), and we'll see how you did.
Next month, we'll crack open a completely different shell script task and see what we can do to help your day-to-day Linux administrative tasks, because we've probably wasted plenty enough ink on a casino game for this year! See ya then.
