For anyone who wishes how to do anything in linux, I highly suggest this book!

I have the Second Edition and I've been using it since 2002! Maybe I need to get the newer one now. :hah: But even this old one has much of the same commands from back then that are still used today! Trust me, you can't go wrong with it.
