Every Monday, we'll show you how to do something new and simple with Apple's built-in command line application. You don't need any fancy software, or a knowledge of coding to do any of these. All you need is a keyboard to type 'em out!
When erasing files on your Mac (or any computer for that matter), trashing a file only removes the pointers to the file(s) on the hard drive. The file is still there, and intact.

We rounded up some of the most utilized Unix commands you should know so you can get started tinkering with Terminal.
