USE AUTOMATOR AND SERVICES IN MAC
Use Automator and Services for speed.
Automator is a tool built into OS X that enables you to build your own workflows of commands, making complex tasks much easier in the future. Use it to build your own little apps that perform a specific task, to make a workflow to modify batches of files, or to create new Services, which are functions you can access from a right-click. You could use Automator to rename a large number of files, to convert images to a different file type, to turn text files in a folder to audio files, and much more.
- To create something in Automator, open it, then choose what type of thing you want to create: each is useful in different circumstances, so click on them to see descriptions. Select the one you want and click Choose (or open an old Automator file).
- Start creating the steps of your workflow by dragging Actions from the left-hand side of the screen to the empty space on the right-hand side. Actions are categorised by application and file type, or you can search for something at the top. Just click an Action's name to see what it does.
- Once you've built up your workflow, you can click Run in the top-right corner to test it (though you won't be able to fully test everything this way). If there are any problems, the part where it failed will have a red cross next to it, and the log underneath will explain any warnings.
