Now that I think about it, you asked for how to check
for a response of just cr-lf. Here's what I should
have sent you:
#!/bin/bash
echo "Please answer yes or no: "
read answer
if [ x"$answer" = x"" ];
then
echo
echo "*** Invalid Response! ***"
echo
exit -1
fi
case $answer in
'yes')
echo "The answer is YES!!!!"
;;
'no')
echo "The answer is NO!!!!"
;;
esac
