For me out of university, it was a co-workers books (some of which I ended up buying) that help me understand the role of UNIX better (I used the alpha machines at university, but was thrown into HPUX/Solaris at work..)
I think this was one: https://www.amazon.com/Advanced-Programming-UNIX-Environment...
Of course a little out of date now, but a lot of the general concepts are the same.
Unix Power Tools helped me a lot as well. https://www.oreilly.com/library/view/unix-power-tools/059600...
How did others learn this stuff?
