#================================================= Modify the given template by changing the function names, modifying menu to give choices that reflect the new names. and an action section that calls the new functions by their new names. You must have at least 5 functions that can be called form the menu. Good indentation. Good comments. 5 UNIQUE FUNCTIONS Run your script file, choosing each option from the menu.

Upload a screen shot of the runs along with you your shell script. ====================================================================

Template of the program is given below:
