There are no such things as "stupid" questions. However if you think your question is a bit stupid, then this is the right place for you to post it. Please stick to easy to-the-point questions that you feel people can answer fast. For long and complicated questions prefer the other forums within the support section. Before you post please read how to get help
I recommend the INX liveCD - http://inx.maincontent.net/ It's more designed as a showcase of what the "Command-line" can do, even graphically, but it also has a good command-line tutorial, and a menu interface.
If you have a question that has been answered and solved, then please edit your original post and put a [SOLVED] at the end of your subject header Hint - use a google search including the search term site:forums.linuxmint.com
