Yes I have, and more than you have apparently. And as numerous others have told you repeatedly, SPELL OUT YOUR WORDS.

And if you bothered to read any of the links that were posted, you'd see how terminology evolved. Please do so.

Exactly

hi,
lets diffrentiate linux and unix, although they belong to same family(well we can say that.).

Unix came on scene when they were operating systems designed with paticular machines in mind. They were all in machine level language(human unreadable ).s/w for 1 machiine wouldn't run on another, wow loads of complication in computer industry i believe...

Now in 1962 MIT + ATT&T BELL + GE made MULTICS(Multiplexed Information & Computing System), well which was a failure, for reasons like no multitasking....
In 1969 att&t withdrew its team from MULTICS project and got invloved in developing a flexible OS and would run in more than 1 type of hardware..
in 1973 Dennies Ritchie and Ken Thompson worte entire system in c language and it became the strongest feature of unix...

Hhowever the US goverment banned att&t from selling of the software and was forced to distribute to academic and research institutes at nominal fee like $15.00...

So now thw university of califonia, Berkley created their own unix called BSDUNIX, this version became very popular, they rewrote the whole OS and gave unix features like vi, C Shell....they also offered TCP/IP.. and made internet possible in unix...they also distributed free to many companies, att&t also did :)

now as unix got so popular bussiness circle caught intrest in it, RESULTING unix was no longer free..

Well many compinies started making there own version of unix, and BSD system was foundation for many..
Sun made SunOS (Solaris now), HP-UX by hp, DEC by digital unix, AIX...
AS unix was losing its originlity...many compinies coming up, att%t sold its uinx bussiness to Novell, who later turned over unix trademark to X/OPEN now merged with THE OPEN GROUP till date....

There was some who had different ideas in his mind.
MR LINUS TROVALD & MR Richard Stallman
trovald is father of Linux(quite controversal)
stallman runs Free Software Foundation (fomerly know as GNU-a recursive acronym thatstans for GNU's Not Unix )

Many of the linux tools were supplied by GNU.
Linux is distributed under GNU's General Public License(GPL), which makes mandatory for developers to make the source code available for public..

OK 1 imp point
gnu wrote all replacement tools for unix(bash,ls etc..), and created complete set of tools, liberies..etc..and put them under GPL.
gnu had all tools but they did not have KERNEL and linus trovald came as saviour as he was working on unix like kernel as self intrest project..



So gnu and trovald's kernel was brought together to form GNU/Linux(popularly known as linux.)
trovald's kernel is now professional kernel for linux.

the most popular flavors of GNU/Linux include:
Red Hat, SuSE, DebianMandrake...etc...
these flavor are shipped in cd/dvd free of cost or also can be downloaded on internet ...
also unix is no longer availabe in original form...some using its name have to pay...

Linux is a unix implementation which is unix like and falls under FSF(former GNU)

You are absolutely correct.

thanks :)

Uhh...not really. Suggested reading:

And it's Torvalds, not trovalds.

Thanks for ur feedback.

Spell out your words...LQ has rules against text-speak.

Hmmm......
By the way LQ is what? Can u please spell out?

LQ is the short-form of LinuxQuestions.
e.g is the short-form of example.
Feb. is the short-form of February.
J&K is the short-form of Jammu and Kashmir.

"u" is *NOT* the short-form of You !!

SMS language is not allowed on this technical forum.
Is that clear now ?

Well i do have habbit of using single a double characters to represent a word..I appolozise for that but can't promise it won't happen in future.
We do have better thing to focus on, atleast i belive....

If gurus and seniors members really feels that Iam aginst the rules and i dont devserve to be here, goahead, blow me off!

Regards.

The way you are arguing it is very difficult to believe that you are 63 !!!!

The reason why SMS language is not allowed on technical forums is that many people visiting this site are not native English speakers ! When you write "ur" instead of "your" and other things like that, they may find it difficult to understand.

Secondly using SMS language on INTERNATIONAL technical forums is considered to be immature behavior.

Hmmm.... Ok

tnx all

It is a good question that can be answered on many levels. Linux indeed is a part of UNIX family. It shares many design and user level features. Linux was growing as a system of many projects, without any central authority. Today, though, Linux "brands" regulate their corresponding distros. On user level, they are very close, as in a case with Linux and OpenSolaris, the difference is marginal. You may find useful, UnixAcademy.com for questions like that...

Hope it helps.
