I learned Unix through its manpage. I learned abotu sh, awk, grep, I learned about sockets and tcp, I learned about semaphore and shared memory. When I started working on Unix, in the early 90s', it was on a true-to-form physical VT220. I quickly learned to run make in the background so I could read the manpage while compiling.
