I'm new to Ubuntu. Last night I installed GNOME Shell from the Ubuntu software manager. I really like this desktop environment. What the difference between doing this and installing Ubuntu GNOME? Would it be better if I downloaded Ubuntu GNOME instead of using the GNOME shell in place of Unity?
Also, if I get Ubuntu GNOME will the command lines used in terminal be different? I'm very new to Ubuntu so I don't want to start learning new command lines right now. For example, to install something it would still be
sudo apt-get install PackageName correct?
Do different ubuntu flavours use different command lines in Terminal? Ubuntu different from Lubuntu different from Kubuntu, different from Ubuntu Gnome?
