1) Start an application.     a. This app simply needs to a running loop until some event has occurred. Meaning that the program will merely sit there waiting to be stopped.     b. You must create a file that contains the application name (file name) and the PID (inside of the text file) 2) Stop an application     a. This will effectively terminate the application that you created. This must be done by finding the PID from the processes that are still running. 3) Status of the application     a. This portion will need check for the existence of the application if it is running. You must give a status by statement indicating if it up or down along with:         i. The PID         ii. The PPID         iii. How long the application has been running
