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.

BSD was embroiled in a messy legal battle with AT&T over Unix copyright. Businesses wouldn’t touch it with a ten foot pole. That’s what really enabled Linux to be anything more than a hobby protect. And we’re all worse for it.
