Question

In linux your task is to automatically start and stop the ‘gnome-calculator’ application with the following guidelines:

1. Create a script that will accept either a stop, status or start argument.
2. You should create the necessary link files in startup section under /etc/rc2.d using 159 start. Meaning you should have S159gnomecalculator
3. The program must contain a ‘case’ statement and set the proper local variable.
4. Please provide the script along with a screenshot of your link files.
