FOR A GNU WORLD
The name “GNU” is a recursive acronym for “GNU’s Not Unix.” “GNU” is pronounced g’noo, as one syllable, like saying “grew” but replacing the r with n.
The program in a Unix-like system that allocates machine resources and talks to the hardware is called the “kernel.” GNU is typically used with a kernel called Linux. This combination is the GNU/Linux operating system. GNU/Linux is used by millions, though many call it “Linux” by mistake.
