Understanding the 'Terminal to Launch' script in Environment Setting

[Zaubertrank]

Can someone explain to me how to modify the default script in the 'Terminal to Launch Console Programs' script.  By that I mean is there some explanation of how to write in whatever language they are using with all the -e's and what not I don't understand it.  It keeps launching multiple console windows and in the default background and some other stuff... btw I'm using a mac.  Thanks.

What do you want to achieve?

Well I would like it clear all the info that pops up at the beginning when terminal launches, and I want it to launch in a different background style.  I realize now that it is osascript which is some form of applescript as far as I can gather.  That's as far as I've gotten so far.
