Well I reinstalled Mac OS X today.

And I am very intrested in unix, but I have a few newbie questions.

1. What is sudo, I have seen it but what does it do??
2. Is there a way to connect online via the CLI
3. Is there a way to allow peopel to telnet into my computer on a network, and use it a bit like a shell account????

4. How the hell do you quit emacs?!?!?!
5. Does Mac OS X come with gcc like in unix.

6. What is xDawin.

Well thats all of them.

I'm a relative newbie to Unix myself so I'll see if I can help some.

1. Sudo is a command that allows you to run a command in root context, i.e. as if you were root.

2. & 3. If you enable the option for terminal apps in sharing, you can access the box remotely using ssh. This is a more secure version of telnet that encrypts your password and traffic between your ssh client and the destination. This is a "shell" account. You just use the account you have set up on your Mac OS X box. It's almost like being there


Now 4. - 6. I leave up to the real experts

Here is an excellent four part tutorial for newbies and I think you will find it most helpful. I'm most definitely in that category.

1, 2 and 3 have been covered.

4: Type Ctrl-X Ctrl-C (yes, that's screwed up. emacs is like that. My advice: don't use it unless you have to)

5: Mac OS X includes cc as the default compiler if you install the Developer Tools CD. gcc isn't installed by default. I don't know what the status of gcc on Mac OS X is.

6: Darwin is the name given to Apple's Unix kernel/subsystem (the set of software at the heart of the system). It's akin to 'Solaris' (Sun's Unix), 'irix' (SGI), 'AIX' (IBM), etc. Aqua is the graphical interface installed on top of Darwin.
If you know what you're doing you can download the source for Darwin and make kernel-level changes to the operating system - not advised for the faint of heart.

The cc compiler in Mac OSX developers tools IS gcc - check out http://developer.apple.com/macosx/ for details.

Yes I am aware of all that, what I am asking is what is xDawin?

I saw screen shots of it in a different post here.

Thanks everyone for your help.

xDarwin is the port of X windows (the unix window system) to OS X. basically, it lets you run and display graphical unix programs (x windows programs) on OS X, either concurrently with OS X or on a separate screen (full screen mode)
