From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux and Unix systems have historically always been designed to be easily configured and controlled with human-readable text files. Most apps you use on Linux can be scripted. So the better you get at using every-day Linux/Unix apps, the more you might want to tweak them to make it easier for you to use. To do this, you need to learn a little bit about how to write configuration files, and how to write simple scripts. This also helps you to automate things on your computer more easily, since all applications can talk to all other applications using a human-readable programming language. For managing all of this, a good editor is extremely helpful.
When you take things to the extreme, you can start using Emacs, which contains an entire Lisp programming environment for manipulating text. You can replace all of your configuration and scripts with a single programming language (Emacs Lisp). And Emacs can replace almost every single app on your computer where text is involved, from simple scripting and configuration all the way up to web browsing, chat, and email.
