I want to have a selector in a “case” menu, so I show the options:

   1) option A
   2) option B
   3) option C

Then read the choice (let’s say it’s B), remove the previous menu and show this instead:

   1) option A
 » 2) option B
   3) option C

How can I do this? I know we can remove the current line with echo -ne "\r", but I have no idea of how to do it with several

    clear wipes the whole console, I prefer to keep the previous lines, and only remove some of them
