Direction

Using your favorite Linux text editor, gedit, vi$,$ ed$,$ or nano, create a shell script called YourUserName$\_$final$1.$

Test your YourUserName$\_$final$1$ script file to verify everything works on your system.

Note: You must replace

YourUserName.sh with your actual username for the script's name.

The script's output after the execution must look similar to the sample run on this page.

You must use your full name as a comment in the script.
