Can someone give us dummies an overview of the shell environment.
I see you haven't been answered and I'm not surprised. An overview is much like writing a "Shells for Dummies" textbook.
I suggest that any book on Linux is a reasonable place to start. The shell in OS neXt depends on Darwin which is an open source version of BSD (Berkely) UNIX rather than Linux but Linux has much more available documentation and is not that much different.
O'Reilly is a good publisher. Their "UNIX in a Nutshell" is a standby of mine. I personally use the books on NEXTSTEP published by a company, Next, that Steve Jobs once ran but they are not widely available. Il like to refer to MacOS X as "OS neXt" because it gives proper academic credit to its heritage.
There is also a lot of stuff on the Apple web site. Join the Apple Developer Connection - it's free - and download some of the stuff there. Learn to use the Terminal application and do "man command" to see the official;documentation for the things you can do. What are the commands? See UNIX in a Nutshell. Start with cd, ls, cp, mv. and do install the Developer Tools.
You'll find that shell and perl scripting are far easier than AppleScript because there isn't nearly as much guessing involved. But there is a learning curve to climb and the terse set of commands bears little resemblance to English; there is typically only one correct syntax.

Applescript syntax is like English spelling:
Roughly, but not thoroughly, thought through.
