neat. Great way to explore the systems. 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-3rd/dp/0321637739 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 Of course a little out of date now, but a lot of the general concepts are the same.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/0596003307/ https://www.oreilly.com/library/view/unix-power-tools/059600... How did others learn this stuff?
