What exactly is so great about Unix and Unix-like software? /g/'s obsession with all things Unix is almost cult-like.
They believe in following industry standards so that software is compatible with other software.
Microsoft, Apple only care about maintaining compatibility with software that they wrote and sell.
It's supposed to be very handy for programming. Also UNIX is nothing but a set of rules, a standard. It means that anything UNIX should work about the same, I can imagine this is usefull when working with different operating systems and such.
And Linux is not GNU.
Linux roughly follows UNIX guidelines but is not certified as UNIX. However it follows the POSIX specs more closely though it is still not certified as POSIX because it would be too expensive.
OSX has been POSIX certified though.
It's a much more enjoyable experience for me on servers, being a standard for over thirty years is a plus too meaning it will be reasonably well documented.
GNU/Linux maybe, UNIX is far from free.
That's pretty false, Windows is only still around BECAUSE it's compatible with more than just what Microsoft writes for it.
>GNU/Linux maybe, UNIX is far from free.
The original Unices are "free" under 4 clause BSD and I'm pretty sure 1.0-4.4BSD are also free now that the old Unix source codes have been freed up.
OpenSolaris and its derivatives(illumos) are free under CDDL+MIT/BSD.
The various remaining descendants of the BSD linage are available under 2/3 clause BSD or equivalent.
The only part that isn't "free" is the trademark. associated with the UNIX name.
>Dennis Ritchie, one of the original creators of Unix, expressed his opinion that Unix-like systems such as Linux are de facto Unix systems
