I have been using Linux as my daily driver for quite some time (around 5-6 years) and usually manage to get whatever needs to be done. However, I now wish to learn it in a more structured manner, which includes understanding utilities and the workings of Linux. What resources should I look out for?
What? No.
At least in all the libraries I’ve been to in my life there is a dedicated section for operating systems, which contains a subsection with just Linux books. You can ask the receptionist “Where is the Linux section?”, walk up to it and there it is. And you can grab a book and skim through it to see whether it suits you.
How is that not information on exactly that specific topic?
Genuine question:
Have you ever been to a library when looking for something specific? Was your experience vastly different from mine?
