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.

Sometimes you don't even have the luxury of vi. Any moderately advanced Linux user should probably learn the basics of sed. Just knowing how to insert text and save it can fix a system that's stuck in recovery. Even if it's just to add a comment in front of a line in a config file.
