Pro Bash Programming teaches you how to effectively utilize the Bash shell in your programming. The Bash shell is a complete programming language, not merely a glue to combine external Linux commands. By taking full advantage of Shell internals, Shell programs can perform as snappily as utilities written in C or other compiled languages. And you will see how, without assuming Unix lore, you can write professional Bash 4.3 programs through standard programming techniques. This second edition has updated for Bash 4.3, and many scripts have been rewritten to make them more idiomatically Bash, taking better advantage of features specific to Bash. It is easy to read, understand, and will teach you how to get to grips with Bash programming without drowning you in pages and pages of syntax. Using this book you will be able to use the shell efficiently, make scripts run faster using expansion and external commands, and understand how to overcome many common mistakes that cause scripts to fail. This book is perfect for all beginning Linux and Unix system administrators who want to be in full control of their systems, and really get to grips with Bash programming.

If you are looking to extend your iOS programming skills beyond the basics then More iPhone Development with Objective-C is for you. Authors Dave Mark, Jayant Varma, Jeff LaMarche, Alex Horovitz, and Kevin Kim explain concepts as only they can—with code snippets you can customize and use, as you like, in your own apps. More iPhone Development with Objective-C is an independent companion to Beginning iPhone Development with Objective-C. That is, it is a perfect second book, but it is also a great book for those looking to improve their skills who have already programmed for iOS. In particular it includes a series of chapters devoted to Core Data, the standard for Apple persistence. The authors carefully step through each Core Data concept and show techniques and tips specifically for writing larger apps—offering a breadth of coverage you won’t find anywhere else. More iPhone Development with Objective-C covers a variety of other topics, including Multipeer Connectivity’s relatively simple Bluetooth/WiFi peer-to-peer model, MapKit, and media library access and playback so that your applications can utilize media on your users’ computer. You’ll also find coverage of Interface Builder, Live Previews and Custom Controls and some advanced techniques for debugging your applications. The book is filled with useful topics that will bring your programs up-to-date with the new functionality built into iOS.

So you have a great game idea for iPhone or iPad, but Objective-C just seems a bit daunting. What are your alternatives? The App Store is very picky about languages, but there is hope: Lua is a versatile, lightweight, fast, and easy to learn language that you can use to build your iOS games and get them accepted into the App Store. Learn Lua for iOS Game Development walks you through the Lua basics, then shows you how to create games using the top Lua frameworks like Corona SDK, Gideros, Moai, and even how to create games on the iPad (not just for the iPad) with Codea. You aren't tied to Xcode and Objective-C -- you can create all sorts of amazing games with Lua. But if you already have an existing iOS game, you'll also learn how to integrate Lua to extend the game. If you're an aspiring or current iOS developer, you need to know Lua, and Learn Lua for iOS Game Development will give you just what you need to do that.
