Unix: History and Memoir
summary
Unix originates at Bell Labs about 50 years ago and starts as a three-week prototype on a PDP-7, moves to the PDP-11, and by 1975 Sixth Edition is ~9,000 lines and already portable because the kernel and toolset compile in C. It introduces pipes for chaining small programs, text-as-data conventions, tools like grep and awk, the man‑page documentation style, and portability that spawns workstations, Linux (1991) and huge Internet infrastructure; Plan 9 contributes UTF‑8 as a lasting legacy.
