The makers of C and UNIX introduce you the basics of the system, in 1982.  Much of this is still the same in a modern Linux or OS X Terminal, and hidden somewhere inside your iPhone or Android. They talk about programs with a single purpose, directing output with pipes, and even mention sharing programs with the community.  Curiously it looks like they have lots of orange and hot pink items in their offices, like phones, notebooks, and even walls.
