Check the select command in the bash manpage.

Alternatively, write your own like this:

return=0
while [ $return -lt 1 -o $return -gt 3 ]
do
	echo "1) Option 1 (default)"
	echo "2) Option 2"
	echo "3) Option 3"
	echo
	read -e -p "Please select an option (1,2,3): " return
# or use the following for purer sh, as opposed to bash
#	echo "Please select an option (1,2,3): \c"
#	read return

	case "$return" in
		"" )
			return=1 ;;
		"1" | "2" | "3" )
			;;
		*)
			return=0 ;;
	esac
done
