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.

That's the one! I learned vi with that website. Turned me into a big fan.
Just out of curiosity, do you know of a good resource for learning awk, sed, and grep?
There are two really good O'Reilly books: https://www.oreilly.com/library/view/sed-awk/1565922255/ and https://www.oreilly.com/library/view/mastering-regular-expressions/0596528124/ (regex in general)
-- not sure if these are still available as standalone pdfs; but back in the day I worked through them in part, and they were extremely helpful.
