I just started to learn linux and want to lay a solid foundation.

When I first started to learn linux, I wanted to lay a solid foundation-general Linux technology-Linux technology and application information. The following is a detailed description. I have just learned about linux recently. Some of my predecessors have said that it is best to read more basic books, such as operating systems and microcomputer principles, to learn about linux. So I bought William Stalling's "Operating System-essence and Design Principles", from the Machinery Industry Press. After reading over 10 pages, I think it is very difficult. It may be because my foundation is poor and I don't understand it in many places. I heard this book is easy to understand before, so I immediately bought it. However, after reading more than 10 pages, I think it is a bit difficult to understand .... I also know that it is crazy to understand it all at once. The key is to be patient and stay interested in linux. I just have a question here. I want to ask my predecessors if there is anything wrong with my learning order. I plan to read William Stallings's operating system and read the computer principles book, I have never touched on this book before, so I don't know how to study properly. This is because william's operating system does not seem to have many terms in mind. So I 'd like to ask you if you have any questions about the learning sequence?
