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 this
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
