I > know that Linux is based on Unix, but does FreeBSD originate from Linux or > Unix? There are two basic "styles" of UNIX; "BSD" and "System V" (System 5). BSD came out of UC Berkeley, System V came out of AT&T. There are some differences in file locations, command parameters, the startup scripts, and sockets vs streams, but neither is clearly better or more popular than the other. Most UNIXes today are actually a mix of the two flavors. For legal purposes, neither Linux or FreeBSD share any copywrited code with either SysV or BSD. They were written to do the same thing, and often code has ended up identical, or nearly identical to real UNIX, but supposedly it was pretty much written from scratch. Linux tends to be more SysV-ish and FreeBSD tends to be more BSD-ish. ---------------------------------------------------------------------------- DDDD David Kramer david@thekramers.net http://thekramers.net DK KD One last warning: don't believe anything that you read in this DKK D document.
