hi i was wondering if someone can help me with a while loop..i have been looking at this for hours and dont no wut to do..
i have to make a menu style.. to have a beeter understanding i have linked a photo at the bottom...

Description: If the “output.txt” file does not exist, then the user is presented immediately with the Main Menu. The user is kept locked into the menu interface, until option # 5 is entered. The while/do/done looping construct is to be used to achieve this. Each menu item is processed using the case/esac branching construct.

1)option 1
2)option 2
3)option 3
4)option 4

5)exit

enter menu option:
