Where to "practice Linux" terminal commands
(lemdro.id)
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.

This is the sort of thing I was talking about with "Don't go running commands [...] unless you're sure what they're going to do [...]"
I did a breakdown of this one on the snoosite back in the day. Searching "fork bomb" on YouTube is probably a better way to get that breakdown these days.
