How to install a .tar.gz (or .tar.bz2) file?
I have downloaded eclipse-jee-juno-linux-gtk.tar.gz file, but i don't know how install it.

You will see the eclipse file in the folder double click it and that is all.
You can also use a normal GUI for this as well, So in most cases its a simple as right clicking on the file and selecting "Extract" or similar..
