Have a look here: http://www.tldp.org/LDP/abs/html/index.html
It should get you started.

 

I implemented this just for fun. But this sounds so much like a homework assignment that I'm only posting a few lines (the looping part) of my solution.

Code:

#!/bin/sh
...
while [ $n -gt 0 ]; do
    ...
    n=$[n-1]
done

Don't forget to make the file executable with 'chmod +x scriptfile'.
