Not at all. Both Unix and Windows are trademarked and copyright protected so they cannot share a common code base.
It is the source code on Unix Level 6.
If I understand your question....vague as it is....yes, the Unix OS source code is free and open source.
The true Unix source code is copyrighted; it doesn't exist anywhere specifically on the net. If you are interested in how something works in Unix you are better off looking at the Linux source code that accomplishes that task.
If the program is in source code and stored in a file, use the 'cat' command to list out its contents.
The "basic concept" of Linux is a free and open-source Unix-like kernel.
In a recent court case it was decided that Novell owns the right to the source code.
Unix is not open source, it is proprietary. Linux is the open-source version of Unix.
Almost all Unix systems are proprietary; they are not open source, and you usually only get the binary modules, not the source code.
Unix is NOT open source, it is proprietary copyrighted code owned by AT&T and you must purchase a license to use it, as you do on Windows and Mac OS X.However both Linux and GNU are open source OSs with equivalent functionality to Unix.
proprietary UNIX
A source file is typically a readable, Ascii file, that is not the result of a compiler or translator to binary machine code.
In a sense it was free; in the early to mid-70s you could get a copy of Unix (without source code) from Bell Labs with only the cost of the postage for the materials.
