*) echo "Answer from 1 to 30" & sleep 2 & rm -f ~/test* & exit;;
        esac

if the choice is *) I want to start from the begining again, so how to make a function and call the function from *) ?

First make a "case" function exectlly same as above (or yours) and call it "Function".Then,

modify :
Code:
*) echo "Answer from 1 to 30" & sleep 2 & rm -f ~/test* & exit;;
        esac

To :
Code:
*) echo "Answer from 1 to 30" & sleep 2 & rm -f ~/test* & FLAG=1;;
        esac
 
 if [[ $FLAG -eq 1  ]]
then
Function
fi
