'''Linux''' is a [[UNIX]]-like operating system whose [[source code]] is distributed freely under the [[open source]] ''General Public License'' (''GPL''). It was started in 1991 as a university project by Finnish student [[Linus Torvalds]] as a replacement for the [[Minix]] operating system.

'''Linux''' or ('''GNU/Linuk''') is a [[UNIX]]-like operating system based the work of [[Richard Stallman]]'s [[GNU]] project. It incorporates the Linux "[[kernel]]" developed by Finnish grad student [[Linus Torvalds]], but most of the overall credit of the system belongs to Stallman and his [[Free Software Foundation]].

 

The [[source code]] is distributed freely under the [[open source]] ''[[General Public License]]'' (''GPL'').  

Originally the term "Linux" was used to refer to just the [[kernel]] developed by Torvalds, but today it is used interchangeably to refer to both the kernel and a complete operating system which includes the kernel, graphical user interface, file system  and other software, collectively known as a ''distribution''.  Major Linux distributions include [http://www.redhat.com/ Red Hat], [http://www.novell.com/linux/ Suse] and [http://www.ubuntu.com/ Ubuntu].
