Screen Capture in Mac using Terminal

I figured, there should be some kind of terminal script out there which enables us to take the screen capture of the desktop. This will become real handy when we need to produce consistent screenshots for the Google Earth Images for my results. Furthermore, in order to crop it nicely, there is a code too!

Close mac Terminal after you are done

The exit command:
It works if the following setting is done:

Terminal
>Preferences
>Settings
>Shell
>Prompt before closing: never
or
> When the shell exits:
select: close if the shell exited cleanly

The following kills the terminal:

killall Terminal

So, if I want to kill the terminal after I am done, I will simply add:
killall Terminal
instead of kill
