Fedora

@all :

thanks alot. I have been using Linux (openSUSE 11.1 and .2 + fedora 12 )for last 1.5 years but just one simple doubt is there perhaps VBE tried t male me clear the same as follows but still i am not getting :

is unix is the same what DOS means to windows ???
and second ..

From the Wikipedia page on UNIX (the one you've already linked to) And if you read the history of UNIX on the same page, you'll learn that the original AT&T UNIX hasn't seen any further development, but instead the brand UNIX is now managed and defined by the Open Group, and more specifically the Single Unix Specification (SuS). Any Operating System that is certified as SuS-compatible may call itself UNIX.

thanks to all.
so can we say that "the terminal program in Linux (unix ) is the same what command prompt program ("dos&quot means to windows ???"

So can we say that the utility named Terminal, bundled with almost all distributions, is actually nothing but Unix??

and and.... can we say that these openBSD,freeBSD, netBSD,PC-BSD are all UNIX OSes ???

No. The only thing DOS, Windows (NT, newer than 98), and Unices (plural of UNIX) have in common is that they're an OS. The "terminal" can be the same program across different Unices. It's just a program that communicates between a user and another program, nothing more, nothing less. And a single program can't be UNIX, as that term includes not only programs, but also APIs, filesystem layouts, ...

Again, read up on the history of UNIX in that Wikipedia article you've linked.

Yes, the *BSDs are Unices. So is Solaris, HP-UX, AIX, Tru64, and Linux, as they all support a certain set of common APIs, programs, ...

aarsh... simply download one of the Linux flavour Fedora core from the web fedoraproject see below link

http://fedoraproject.org/get-fedora

and install it with someones help. After installing Fedora core you can use UNIX from the Fedora OS by terminal or console.

you can't use UNIX because UNIX is not a tool or program... all you can use from within a terminal session are the tools (programs) that are installed on the system. tools like "vi" or shell buildin commands for scripts like "while".

Terminals and GUI's are both just programs -- linux makes no special distinction between them, a GUI program is just an ordinary program that happens to be talking with an X server... Everything you see and interact with is just programs running inside the OS, the OS is kind of intangible to the user.

What Linux fundamentally is, is a kernel. That is -- a small program, about a meg or so in size that the system boots raw from disk. It handles all devices and loads programs, runs programs, switches between programs, lets programs talk to each other, and deals with files when programs tell it to. That is it, there's no shell or GUI built in. Everything like that in a Linux distro are programs that just run inside Linux.

IOW it's a completely barebones "utility" to run programs inside. It runs one and only one program automatically, on boot: init. Think of it like autoexec.bat, except it's optional for DOS to have an autoexec.bat but mandatory for Linux to have an init; without an autoexec.bat, DOS just drops to a command prompt, but init would actually be the command prompt(or at least be responsible for creating one), and if there's nothing there then what? It's also very different from DOS in that it's multitasking, of course.

So, UNIX describes a broad design for two things:
This is very different from Windows where it's all treated like one inseperable block.
