Shell 在ZSH脚本中显示倒计时？

我有一个zsh脚本，从中读取用户的输入，一段时间后默认为“是”

我目前正在使用类似于

read-q-tt5

的东西来实现这一点。以下是实际代码：

echo "${Red}Errors${RegF} were detected in the output of $i."
read -q -tt $CONFIRMATION_TIMEOUT "REPLY?Proceed? [Yn] "
echo
case $REPLY in
    'N') ;&
    'n') echo "Aborting..."; exit 0;;
    *) ;;
esac

我得到：

Errors were detected in the output of groups.xml.
Proceed? [Yn] 

但是我想在屏幕上显示一个倒计时，可能是这样的

Errors were detected in the output of groups.xml.
Proceed? [Yn] (5)

这个数字每秒钟都在减少

我有什么办法可以做到这一点吗

谢谢大家!

PS：我也很感谢您在这段代码中对可以更好地完成的事情的评论。

您可以做如下事情：

echo "${Red}Errors${RegF} were detected in the output of $i."
{ i=$CONFIRMATION_TIMEOUT; while test $((i--)) -ge 0; do 
  printf "\rREPLY?Proceed? [Yn] ($i)"; sleep 1; done; } &

read -q -tt $CONFIRMATION_TIMEOUT
kill $!
echo
case $REPLY in
    'N') ;&
    'n') echo "Aborting..."; exit 0;;
    *) ;;
esac
