Thanks to both of you for responding. The empty quotes works best for
what I wanted to do (which I should have been clearer on in the first
place). I wanted to make the first choice in a menu the "default", ie,
just hit <return>, and the empty quotes allow me to do that:
echo -e " Your selection, please: \c"
read ans
case "$ans" in
1 | "" ) echo "Selection 1";;
2 )
echo "Selection 2";;
3 )
echo "Selection 3";;
* )
echo "Invalid choice";;
esac
