It's how you use a computer when you have no graphical desktop and mouse.

Like in the 'good old days' of DOS and CP/M.

Or when you want a really secure system.

If your looking for the actual inner workings of how a "shell" operates I can't help you.

A Shell takes , "stdin" and processes it. stdin is standard input ie... keyboard or mouse and processes it to either stdout or stderror. standard output (what you see on the screen))
