Beej updated the classic Linux network programming guide

Has anyone actually even tried the K&R book in the past couple of decades and not run into issues like the assumption of unbuffered shell output? You get like one or two chapters in and things are already behaving outside of how they did when that book was written in the 1980s. It's a classic, yes, but I don't recommend it to anyone outside of people writing code in C89 for vintage systems... Yet the amount of suggestions I see from people who haven't actually learned C from scratch since the 1990s to read that particular title is high enough that I can't do anything but scratch my head over it. Tons has changed over thirty plus years.

If you're looking for something up to date I'd recommend this:

I taught myself C from K&R 2, and a platform-specific (Amiga!) book, back when I was a teenager. In three decades, not much has really changed with the core language.

While the core language has stayed the same the tooling and development environment has changed quite a lot. Proper modern compiler flags (-Wall etc) for example would be a huge help to new learners and for best practices, but k&r isn't mentioning these. I still think it's a good book but if you throw it at someone new to this they're going to be wondering why what they are writing isn't behaving as expected.

K&R2 is hard to beat for size and clarity of writing.

Could you elaborate on the "unbuffered shell output" comment?

I'm guessing he's talking about the putchar/getchar example in the first or second chapter?

Yeah that. It's extremely confusing and where a ton of people stop reading it.
