you already have a full unix system
called
OSX10.x
fink is a package manager
it will help to install a variety of standard Unix applications on your current Unix system.
some of those use a GUI which is different than the one which you have installed.
you are running Quartz ...it is an Apple product.
Other flavours of unix run a special window management server called X-windows.
this is XFree86
that software allows you to install additional window managers which are compatible to Xwindows.
Enlightenment, WM, Blackbox among others...
When you run in rootless mode, it means that you shut off the back ground of the desktop and open the windows over your regular Quartz desktop.
This makes running Xwindows on your OSX seem to be more integrated
fink will help you to download, compile and install a basic <b>working</b> system. Most of the configuration is still up to you.
at this moment fink is supporting nearly 400 packages which you may or may not be able to use.
They are however, operational. Which means you have to spend time reading lots of books to understand the purpose of most of the applications.
Xtools installs a pre-compiled version of Xwindows on your machine and allows you to have an easier time configuring .....
It is not Free.
so go to
www.google.com
and read all about it....
rootless, X-windows, Unix, MacOSX
would be good search terms to begn your education.
otherwise, open the terminal and type
man apropos
return scrolls and "q" will get you out.
also have a look in these areas by typing
in the terminal.app
cd /bin
ls
cd /
ls
cd /usr/bin
ls
<hr><b>
that is unix </b>
<hr>
type "man [any word which you see in those directories]"
man cd
man ls
env
wow! the library is built in......
