Shell Programming and Scripting

I currently have a main menu (using whiptail) and one of the options makes an instance of another menu - sort of cascading fashion.

I like to be able to terminate the current (top) menu and return to the underlying main one.


I was thinking enclosing the main menu in "do... done" block.



I have some issues copying using mouse blocks - it hopelessly breaks the file so I really do not want to try this without having same confidence it will do the job.



Thanks
