Hello! I’m looking for book recommendations for learning programming fundamentals.

To be clear, I’m not necessarily looking for a book on learning language(s), but rather, programming, theory I guess you might call it?

For example, I’ve been playing around a lot in my terminal writing bash scripts, and I just implemented my first function. Another example, I know the phrase “Object Oriented programming”, but have no idea what it means.

I learn well by doing, and I’ve learned a lot just writing scripts and reading about bash scripting, but I also realize there’s a lot about programming at a higher level that I know nothing about.
