General :: Shell Script Fails To Exit / Troubleshoot This?

This is a very simple problem, but I'm scratching my head with others..

In composing a simple shell script in class, we can't seem to get the script to execute fully. script was formatted as follows.

#!/bin/bash
echo "good bye for now"
exit

did, Chmod 755 to make executable
type file name "bye"
runs but wont exit.....
it just echos the type"good bye for now
The instructor says it works for him at home....
But it wont work in class...
Is there a reason it wont "exit" the shell as commanded ?
