Getting started with Linux

The Mac operating system is a Unix-based on graphical user interface. You can therefore interact with your Mac computer using many (most) of the same commands used in Unix/Linux systems. Many of these commands achieve the same things that you can achieve using 'point and click' methods. For instance, if you wanted to create a new folder on your Mac desktop you could click on your desktop, select File > New Folder. But you can also create a new folder using Unix commands in Mac's Terminal.app (which can be found in Applications/Utilities/Terminal).
