UNIX and Linux Shells

If all you do is use the Desktop Environment or a Window Manager, you are missing out on some of the real power of UNIX and Linux. The Shell, what is it? What Does it Do? Why do we need a shell? In this video I discuss the evolution of the shell from 1971 up through 2006, yes more has been done on shells since 2006. Mark Paq did a great job of outlining the history of the shell on UNIX and I am going to augment that with some personal experiences with the Shell and the history I saw as they changed over time.
