linux = UNIX ????
is linux a unix ???
I always though that UNIX was JUST and ONLY, and operating system. Now I try to download UNIX from internet, but the webs always gives me MACHINTOSH, LINUX; AIX, BSD for download. so .. the word UNIX, is just an operating system, or is a KIND of operating system. or it became a kind of operating system with the time. I want to download UNIX, to try, i cannot find it anywhere to compare the performance with linux |

Hi.
The article at http://en.wikipedia.org/wiki/Unix will provide most of the answers to your questions. If you click on the first graphic, you'll see the *nix-like systems that you can obtain for free. Others are proprietary, e.g, AIX, HPUX, and are built to run on specific hardware ... cheers, makyo |

UNIX UNIX-like Linux You should be able define what you can or cannot do after reading the above links. If you want 'UNIX' then pay the $$. If you want a 'UNIX-Like' then choose one. The same goes for a GNU/Linux distribution, choose one that meets your requirements. :hattip: |
Solaris is unix-based , while BSDs and Linux are unix-like.

GNU/LINUX is the complete open source operating system. GNU - GNU is NOT UNIX As UNIX is proprietary u can't download it anywhere.Use GNU/LINUX instead. U can download Solaris ,as sun made it opensource in 2008.Now its opensolaris. U also can download FreeBSD. |

Here is a FreeBSD of the Berkeley unix, that is also free, as well as the OpenBSD here. Performance wise, if you mean speed, a properly configured unix is better than an Ubuntu or "whatever an all-ready-all-around" distro. But a well trimmed GNU/Linux is as fast as a well trimmed unix. The nearest GNU/Linux distro to immitate a BSD unix implementation is Slackware. Linux kernel today stands as a well coded matured kernel, thanks to Linux Trovalds and the many bright boys who spend time and talent to offer a "no joke" kernel to the world for free! Linux is a Unix-Like kernel, it is coded separate but inherited and improved the very strong philosophical points of Unix, such that it is as good as unix itself now. We apply the term "GNU/Linux" for it is the truth. Linux is just the Kernel, but GNU provides the rest that makes it an Operating System. We acknowledge honor to whom honor is due. Read the links Onebuck has provided above, it will shed more light to your questioning. Hope this helps. Good luck. |
thanks all for the reply!!!!
thanks really |

As a sidenote, if you want some fun, go to a library and read some books from the early days of Unix. Then see some books from the time when Windows came around that talk about Unix. Enjoy :) |

But I have never actually used a Unix system besides Linux, so I can't tell you what, if any, the differences are. |
In the movie documentary "Linux Code". It was mentioned that Linus Torvalds started his kernel project on a Minux system. The documentary linux Code can be found in youtube.com.
http://www.youtube.com/watch?v=P7ycppO3gPE The movie is split in 7 parts. BTW, it does not matter to me if linux is unix-based or unix-like, as long it is not windows. - Cheers |

Also check these links: http://linux.wikia.com/wiki/Linus_To...nux_connection http://en.wikipedia.org/wiki/History_of_Linux Btw, minix was an "unix-like" system and not unix. Regards |

and of course remember what GNU stands for....... |
b0uncer, if Unix is not an operating system then this is the first time I hear that. The world knows it was. Well anyway, flashy definitions come from anywhere: it depends on how you define the word. If unix is nothing but philosophy then it would be wise for anyone to turn to philosophers to define what unix is: I remain here in the LQ and be satisfied with how books describe this well implemented kernel. :)
dv502, you don't need to go youtube, you can read linux source code at /usr/src/linux/kernel in your box And btw, resetreset, I have run a solaris and the difference with GNU/Linux/Slackware is both few and many! :-) depending on what you look for. Good luck. |
I am a little unclear on BSD. If I remember during 4.4BSD they were forced to remove all ATT code as per their agreement on the law suit brought on by ATT.
According to this http://en.wikipedia.org/wiki/USL_v._BSDi (If I am reading it right) shows that BSD at one point was a Unix based OS (IE had the original source) but has since rewrote most of it. However I still feel that BSD should be considered a Unix OS not a clone. However this can probably turn into you say tomato I say tamoto |
Well to answer your question. Yes, you can try UNIX, but there is no operating system called UNIX anymore. AT&T sold the right to it around 20 years ago. However, there are still UNIX derivatives around.
Which you try depends on your knowledge. If you're fairly familiar with Linux then try OpenSolaris (www.opensolaris.com). If you consider yourself a bit on expert you can still try OpenSolaris but you may also try FreeBSD (www.freebsd.org). Beware, FreeBSD is command line intensive. |

In practical terms Solaris/BSD/Linux (even MAC/OSX) are near-enough Unix; aka *nix. |
I thought that I was having a stupid confusion, but this post made a really interesting debate of the topic

Hi,
A little searching; Quote:
'The Creation of the UNIX* Operating System' comes from 'Bell-Labs' so there should not be any questions; Quote:
Don't take my word for it, read some of the history. I lived a lot of it and know first hand that 'UNIX' opened a lot of doors for me personally and professionally. :hattip: |
There's a lot of debate about "where to draw the line" when talking about operating environments. But here might be a good rule-of-thumb:

I congratulate the OP for posting a topic that is able to roll call some of the best members of the LQ --it is like a picnic seeing honorable names around :) and it emotes inspiration to everyone hearing from others. Allow me to beg leave from this particular thread. I agree to agree and disagree everyone in peace. Now lets go back to the business of helping the newbies. Good luck everyone. |
