I am starting to get my feet wet in the area of the CLI. I know some things and and learning more every day. I am finding that experience is the best way to learn but I am sure that there are some basic things that I could learn/have a refferance to. My question is...
Are there any good books (or sites) on this stuff? I would like something that starts off slow then also has some advanced things as well.
How did the rest of you learn?
