The first script that needs to be written is automating the shutdown procedure. Write a script that will perform the following tasks:

Prompt the system administrator for all valid input parameters.

Ask if a wall needs to be sent, and if yes, send the message.

Ask if this is a shutdown or reboot, and process appropriately.

In addition, take this opportunity to describe the various UNIX run levels, what each level is used for, and how to boot to a specific run level.

You should also take this opportunity to create the template for your entire class project (also known as the key assignment), and create a Word document that you will add to for each remaining assignment.

Each week, you will add to this document and submit it for grading. As a preview, each section will contain the following:

UNIX Programming (Week 1 IP)
