I did not understand meaning of this line :( below. I only understood
that it will exit while loop if the input has either yes or no. But
then what is " grep { lc $normal eq $_ } "?
last if grep { lc $normal eq $_ } 'yes', 'no';
It's another way to say:
last if lc $normal eq 'yes' or lc $normal eq 'no';
