Hint simple loop back the user input prompt until

Write a 1-2 two page paper in a Word Document that explains what the issue is, what the program solution should be, and the user guide on running the program. As long as you have the three basic components, there is no particular format that your paper needs to be in, however, please make it organized and readable.

Solution: Write a shell script to poll the users what operating system they prefer by giving them a list of available operating systems.

User Guide: Select the appropriate number representing your favorite Operating System (OS) after the question mark prompt.

The example above is a simple problem and solution. What will make the program even better is that you add more code to avoid errors by telling the user that they selected the wrong number and then letting them answer it correctly. (Hint: a simple loop back to the user input prompt until 1, 2, 3, or 4 is pressed). What about storing the result in a file so you can keep metrics on the responses (Hint: Redirection)? How about allowing the user not only to select 4 for Other but capturing what OS they prefer?
