Each and every Linux distribution has a compiled manual for each command itself. You can simply open a terminal by hitting ALT+CTRL+T and then type man command-name to open the manual to learn more about a specific command and what is does. (e.g.: If you need to know about ls.. then type man ls and hit, magic happens!).

You may also refer Ubuntu Documentation to learn more

Best place to start: Man pages. In the terminal type man [command] This will bring up the manual page for that command. (eg. man apt-get) More information can be found here

If you want to learn how to use the terminal, you just have to start with getting a good understanding of the basics and work your way through it.

You will find many good basic guides and tutorials through Google. I will list a few to begin with.

There are also pretty good Youtube videos for absolute beginners:

When I first started using Linux, I found the manual pages confusing and hard to use. But if you learn how to master them, they become a very useful aspect of the terminal.

I don't remember every command I ever used.. I've got the command apropos and google for that :) Enjoy the terminal!

Another good place to start is the book Introduction to the Command Line from FLOSS Manuals.

Note that this manual is not restricted to Ubuntu, and you'll learn how to do a lot of things from the command line using several programs, some of which you might need to isntall in your Ubuntu if you want to use them. No problem, as the book will show you how to install programs as well.
