Unix is popular operating system, developed by AT&T. It is not an open source. But Linux is an open source operating system. So users can modify the kernel and other things to their own desires.
Ex:Redhat, Fedora, Susee, Mandrake . . . are some available linux operating systems

Unix is the foundation for a number of operating systems, Linux is one of them, and probably the most popular.

Well, in addition, I can quote a little part from the README file from the official Linux kernel:



And as it was said, Linux is just a kernel, the distribution includes everything else, GUI and stuff.. and Linux can run on an x86 architecture, the old unix as I know requires a mainframe..

For example, were was Unix like systems and DOS like systems, from them we have one of the most popular unix based system Linux and from DOS we have Windows, even though Windows weren't an OS till NT, it was considered a DOS with a GUI till Windows 2000 appeared.. of course we also had different architectures operating systems like Amiga OS and Risc OS, even though they are still used, but not as much as other mentioned above, somewhere I would need to include Apple too, but I never read to much about the past of Macintosh.

A more simple question would be what is the difference between DOS and Linux, it would be easier to answer

Also, a point to add here is that UNIX is the next common base for operating systems after Windows NT. MacOS X, Solaris, AIX, HP-UX, FreeBSD, OpenBSD, NetBSD, Xenix and a whole lot more!) Linux is just a clone of UNIX, but contains 0 UNIX kernel code.

The work on different hardware architecture... I am not a geek in this here is plenty of inf for you to read:

Linux vs. Unix

Don't forget that Unix is not a freeware!

Replying to pixelsmack

Mach is a kernel. All Linux and Unix have a kernel and protective layers wrapped around it. All have a tool set. Both Linux and Unix are operating systems. The major Unix release types included Posix, BSD, System III, and System V. It was designed at universities funded by grants from the Department of Defense (DOD) to create an omni centralized missile defense operating system and internet. Linus stole the design of Unix and all its commands slightly different, and then renamed it egomaniacally after himself. Minux did the same way before Linus came along. Just like its predecessor, it has '1000 flavors of vanilla'. RedHat is a commercialized release of Linux just as Solaris was of Unix. Incidentally, Solaris topped AIX (Unix from IBM), HP-UX (Unix from Hewlett-Packard). The Tektronix version included BSD and SYSV command sets, as do most releases now. You can find more than one of the same tool on many releases that each behave and take options differently (e.G., "ps -aux" and "ps -edalf").

Is linux part of unix or it is an advanced version of unix?
What\'s The Difference Between Linux And Unix?!?

Tell me the basic difference between linux and unix and also tell me that is linux part of unix or it is just advanced version of unix?

Differences Between Linux and Unix
What\'s The Difference Between Linux And Unix?!?

The major differences:
� Linux is free, while many UNIX, are very expensive.
� Linux runs on many hardware platforms. In contrast, a typical UNIX is proprietary-hardware-bonded (and this hardware tends to be much more expensive than a typical PC clone).
� With Linux, you are in charge of your computer, whereas on most UNICES you are typically confined to be an "l-user".
� Some UNICES may be more mature in certain areas such as security, some engineering applications. Linux is more for the average person who wants to run his own server or engineering workstation.

Linux was developed by college student Linus Torvald. He was in fact developed the free OS by taking features from UNIX. As UNIX was developed by AT&T and it’s very costly to buy and maintain, Linus Torvald developed similar OS with basic architecture and he released this for free in forum. Then number of people inspired by this free OS and contributed to its development. Now Linux is giving computation to Microsoft.

This question is basically answered and nothing useful has been posted. Everything is now redundant.
