I learned by trying out pretty much *every* command in /bin
and /usr/bin. I would read the man page, play with the
command, read the man page some more, and so on. I wrote toy
programs to learn about common libc functions. I tried out
pretty much every vi command to become better at editing.
Fotunately v7 was a small enough system that one could
actually learn something about every command, every device
driver, every syscall, every libc function etc.
I read the documentation bundled with v7 & BSD, and I read
unix source code as well as observed and learned from seasoned
unix hackers. But I would switch to writing (and rewriting)
code ASAP as I learn better by building something. And
debugging. There are lots of learning opportunities there!
The key is not give up until you find the root cause.
Debugging can give a more intuitive sense of how things work
as you start paying more attention to even little things.
