Thank you for the honest feedback! Wondering if you could provide more information on why you think that? Should I go into a lot more depth on a specific topic?

Thank you for the honest feedback! Wondering if you could provide more information on why you think that? Should I go into a lot more depth on a specific topic? Do I need to break down the shell commands with more detail? Regarding your second question - I'm not too sure of a good book and my book isn't really meant for that as I'm sure you've guessed.
