I were you I'd start by looking for a shorter tutorial with some good
examples.
What's nice about awk is the way it's optimized for use in pipelines.
You can run a series of action (blocks of code) against each line, each
action can be preceded by an optional test. There also a BEGIN{} block
where you can do initialization and an END{} block where you can tie
things up. If you don't want to use it that way you can simply put all
the code inside BEGIN{}.
Beyond this unusual structure it's a pretty straightforward scripting
language.
