    What's the difference between Linux and Unix


    I wish someone would write a definitive description of the differences between linux and unix. Like linux uses a package manager and unix uses ports and why?

    This is not a comparision between only two things, there are a lot of unixes.
    wikipedia provides a good overview
    Unix-like - Wikipedia, the free encyclopedia
    You must always face the curtain with a bow.

    Here's a succinct history of UNIX and its variants written in 1999. It doesn't explain the differences but does explain where they came from. A Quick History of UNIX

    Probably pointing out the obvious here but anyway,
    UNIX was designed by Ken and Dennis at Bell Labs and was originally closed source. While Linux was created by Linus and was designed to be an easy to access UNIX-like system for everyone, largely inspired by MINIX.

    I suppose the fundamental difference is there is no direct link between UNIX and Linux. They are separate systems based of the same design principles. That is what it comes down to at the core...
    If you were to look deeper into the source code of most current day UNIX or even BSD systems and compare the code to the UNIX V7 you would find similarities between them.
    Structurally UNIX and its descents (aka BSD, System V R4, Solaris, etc) were built as a complete OS where as Linux was built as a kernel with the eventual union with the GNU platform to create a complete OS. This is most obvious as most UNIX systems have there own build-chain, while Linux uses the GNU build-chain.

    Hope that helps

    Actually it wan't originally closed source. In fact the sources were routinely mailed out to people who wanted them. AT&T began to clamp down on it in the late 70's I believe and some folks at Berkeley created BSD which had no code from the original Bell labs product and was therefore not hampered by the restrictions of the copyright. The story is much more complicated of course.
