I'm new to Ubuntu and wish to learn all about Ubuntu/Linux. I've been using it since past 6-7 months and know basic stuff like few terminal commands, repositories, tweaks, desktop environments etc. I have very basic knowledge but I wish to learn each and every aspect of linux. Can you please suggest me some books or some other source of learning? I found "Official ubuntu book 5th addition" ebook on a website but not sure if that's the right book to start with.
Need your help..
Thanks in advance.
