Linux Terminal

Hello everybody,

I was wondering if there was a place online where I could find out the basics/essentials of the Linux Terminal. I'm not used to how it works as I've rarely ever used Linux so it could help me get up to speed. If there isn't a place online that you know of, maybe you could teach me? I understand when to use sudo, apt-get, wget etc but not what they are.

Many thanks,

Alex

You may already be beyond this but I (and others) have found it helpful:

http://linuxcommand.org/lc3_learning_the_shell.php

doesn't cover wget, sudo apt-get explicitly but is a good background to the shell.
