Unix = Linux?

Hey,

i want to make a hosting-directory, and i'm categorizing all the different packages.
Now sometimes i see unix, sometimes linux.

I'm confused here, is it the same, or is there a difference between them?

It's gonna be a search option: windows, linux, ?unix?, ?maybe more?

somebody knows more about this?

greetings,
tom

According to "official" sources, Linux is not Unix. Certified Unix that is. It derives from and owes a lot of heritage to Unix however. To most people, Linux is Unix. So I think your place is to base it on what your user-base will see it as.

Some people are picky about their hosting distro, so definitely keep that info so people can search/sort by it.

To most people, yes UNIX and Linux behave the same. But, when you get down to the nitty-gritty (at a kernel level), UNIX is most certainly not linux. Kernel modules made for Linux won't work under UNIX for example.

I so totally never clocked that one 8O I always just assumed it was a spin on the creator's name. Doh!

Unix is one of the starting operating systems designed by Ken thompson, Dennis Ritchie (Author of C-Language) during 60s-1970s, parallely developed with C, or infact C is developed on Unix or Unix is developed from C(vice versa). Today any OS which operates are based on Unix and a bit of innoviations on it. Unix has networking feature very early stages itself. Unix has much more features than Linux and is not open source.

Linux is a unix like operating system, but not Unix.

Indeed... even DOS was stolen from an early UNIX.

It was originally a play on the lead author's name.. Linus (Torvalds).

and if you ever want to solve the "How do you pronounce Linux?" argument: here is the man himself.

This is interesting. In 1991, Linus Torvalds apparently posted to a minix newsgroup the following:
The man himself wrote:Hello everybody out there using minix -

I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones.
Famous last words :)

- Linux, OpenBSD, FreeBSD, AIX, HP-UX, IRIX, Solaris, UnixWare are Unix in the general use of the term.

- Only AIX, HP-UX, IRIX, Solaris, UnixWare are Registered Unix which means they have a license from the Open Group.

- OpenBSD and FreeBSD are not Registered Unix, but share common code from the original Unix.

- Linux is both not Registered Unix and does not share common code.
