When working with Unix, you will most likely find it easiest to work with tools at the shell prompt. Using commands such as touch and rm is very helpful, and these commands perform different niche-based functions in much the same way as the whereis command covered in the last lesson. In Unix, there are multiple ways to create a file and edit it.
