A family of Unix-like computer operating systems using the Linux kernel. Linux is an example of free and open source software collaboration. The source code can be used, freely modified, and redistributed, commercially and non-commercially under licenses such as the GNU General Public License. Normally Linux is available as a packaged 'Linux distribution'. Linux distributions include the Linux kernel and the supporting software required to run a complete system. The original Linux kernel was written in 1991 by Linus Torvalds.
