AT&T Archives: The UNIX Operating System
AT&T Tech Channel
A 1982 Bell Labs film hosted by Victor Vyssotsky on the origins and design philosophy of the UNIX operating system, with appearances by Kernighan, Thompson and Ritchie. It shows pipes, filters and a shell one-liner spell checker being built.
HN points people to it as the clearest primary-source explanation of Unix pipes and the small-tools philosophy, straight from the creators.
