We are starting a new automation series where we post tutorials and tips on automating repetitive tasks and batch processing on the Mac. We will cover topics on Automator, AppleScript, Bash scripting and Ruby/Python programming. We give a brief overview to these tools and languages in the first post of the series.
Mac OS X comes with Automator app to assist you to create automated tasks using an easy to use drag-and-drop user interface. Automator and its underlying AppleScript programming language is Apple’s recommended automation tool and language on the Mac. Most aspects of the Mac can be automated and controlled using the AppleScript language. Many third party OS X apps also provide an interface to allow you to control them via AppleScript.
(The definitive guide by Apple on Mac OS X automation is at www.macosxautomation.com.)
