shell - How to detect when user press ESC and do something in shell script

Question

I want to create a poll in a shell script:

echo "1 - What is your name?"
read name
echo "your name is $name"

echo "2 - What is your country?"
read country
echo "your country is $country"
...
...etc...
...

I want if the user press ESC in a question, cancel the question an jump to the next question.

Thanks! I keep in wait for possibles answers!

Answer 1

这是如何知道用户是否选择了转义：

read -s -n1  key

 case $key in
     $'\e') echo "Escape";;
 esac

Answer 2

如果您最终使用 bash shell，您可能对“trap”命令感兴趣，它允许您捕获并处理中断（例如 ctrl-C）
