Beginning Mac OS® X Programming

Chapter 10. Overview of Scripting Languages

With its Unix heritage, Mac OS X comes laden with little surprises that are not traditionally of the Mac but now have a home on the platform. Scripting languages are a good example. Before Mac OS X the support for scripting was limited, aside from Apple's own solution—AppleScript. Now you can run any of the scripting languages found commonly on other Unix platforms and Linux directly from your Mac and not have to sacrifice anything. There are even some advantages to using Mac OS X with these languages, such as Cocoa bridging, which allows you to write great looking Cocoa apps in most of the popular scripting languages.

This chapter provides an introduction to scripting in general and an overview of the most important scripting languages on Mac OS X, from the Bash Shell to Python and Perl. Because it would be impossible to cover all scripting languages in one short chapter, a selection of the most important scripting languages has been made. Each of the languages ships with the Mac OS X system, so you can start using them straight out of the box.
