Z:gnu-www-ja-gnu-linux-faq--de3b55-No code in GNU comes from Unix/en

No code in GNU comes from Unix, but GNU is a Unix-compatible system; therefore, many of the ideas and specifications of GNU do come from Unix. The name &ldquo;GNU&rdquo;, which stands for &ldquo;GNU's Not Unix&rdquo;, is a humorous way of giving credit to Unix for this, following a hacker tradition of recursive acronyms that started in the 70s.
