Hvordan prompter jeg fra mit script, så brugeren skal indtaste en enkelt
karakter, typisk ser man jo noget a la:

"Overwrite?  (Y/n)"

hvor Y er default og der kan tastes 'y','n' eller blot <enter>


Løsning 1:
echo -n "Overwrite? (Y/n)"
read answer # $answer con

Løsning 2:
dialog --yesno "Overwrite? " 0 0
       if [[ $? != 0 ]] ;  then
               echo " Aborted."
               exit
       fi
