What is the difference between Unix and Linux operating system?

The caricatures speak of wizard-like "graybeards" sitting behind glowing green screens, writing C code and shell scripts, powered by old-fashioned, drip-brewed coffee.

While many of Unix's concepts were derivative of its predecessor (Multics), the Unix team's decision early in the 1970s to rewrite this small operating system in the C language is what separated Unix from all others.

As the branches grew from the original root, the "Unix wars" began, and standardization became a new focus for the community.

The POSIX standard was born in 1988, as well as other standardization follow-ons via The Open Group into the 1990s.

This included FreeBSD, OpenBSD, and NetBSD, each with a slightly different target market in the Unix server industry.

What we call the Linux operating system today is really the combination of two efforts from the early 1990s.
