problem piping input to script with echo
I am trying to have a script run without interaction from the command line. So in my script i have a line like this
echo -e "\n\n\ny\ny\n" | ./script
the goal being the ability to mimic 3 Enter presses and 2 'y/n' responses with 'y' followed by enter.
For some reason tho, it is not accepting the 'y' when i run the script and is executing only the \n.
Any help is always appreciated.

I was wondering why ls * | echo does not print the contents of the directory to the screen? The way I see it, ls * returns a whole lot of information, and then we pipe all this info to echo, so surely it should all come to our screen!
Is there a serious flaw in my understanding?
