Shell 编程中关于询问输入的操作

echo "Output folder exists, Type 'y' to clear, type 'n' to quit convertion..."

read reply leftover

case $reply in

y* | Y*)

echo "Commit clear!"

rm -r $Output;;

n* | N*)

echo "Well, you quited convertion!"

exit 0;;

esac

实现了询问用户是否执行删除操作，逻辑不完整，需要补充对其他输入情况的判断，因此只判断生效的就好，修改如下

echo "Output folder exists, Type 'y' to clear, type 'n' to quit convertion..."

read reply leftover

case $reply in

y* | Y*)

echo "Commit clear!"

rm -r $Output;;

*)

echo "Well, you quited convertion!"

exit 0;;

esac
