Learning vi

- [Voiceover] Hello, I'm David D. Levine and welcome to Up and Running with vi. V-I or vi is a text editor that comes pre-installed on all Unix based systems, including Linux and Mac OS X. It's been around forever and although it can be kind of arcane, its ubiquity and power make it a very useful tool. In this course I'll show you how to enter and leave vi, how to move around in a file and make changes, and how to call Unix commands from within vi. Vi does have a steep learning curve, but if you take the time to become familiar with it, I'm sure you'll find it a useful addition to your toolbox.
