I bought an introduction to linux book to learn hacking
Why do you want to learn about Linux and hacking?
My main goal is to learn how to hack the operating system. Maybe I could do stuff with it.
I think it's great that you're going to teach yourself how to use Linux. Learning new things is important for your personal development. I think you should be proud of yourself.
I want to learn hacking, not Linux. Once I can hack I can do all kinds of things.
Learning new things is good. I do hope you don't plan to harm anyone with your hacking.
