The Linux kernel is a
Unix-like operating system
kernel. It is the namesake of the
Linux family of operating systems. Released under the
GNU General Public License (GPL) and developed by contributors worldwide, Linux is one of the most prominent examples of
free and open source software.Linux was written by
Linus Torvalds in 1991. Early on, the
Minix community contributed code and ideas to the Linux kernel. At the time, the
GNU Project had created many of the components required for a
free software operating system, but its own kernel,
GNU Hurd, was incomplete and unavailable. The
BSD operating system had not yet freed itself from legal encumbrances. This meant that despite the limited functionality of the early versions, Linux rapidly accumulated developers and users who adopted code from those projects for use with the new operating system. Today the Linux kernel has received contributions from thousands of programmers.
