Ease of use
Automator allows point-and-click ease for automating repetitive tasks. Automator enables the repetition of tasks across a wide variety of programs, including the Finder, the Safari web browser, iCal, Address Book and others. It can also work with third-party applications such as Microsoft Office or Adobe Photoshop.
How to use it
Automator comes with a library of many Actions (file renaming, finding linked images, creating a new mail message, etc.), all of which act as individual steps in a Workflow document. A Workflow document then can be used to carry out repetitive tasks. A user can also save these Workflows so that it can be used over and over again, whenever it is needed. UNIX command line scripts can also be invoked as Actions.
