我做错了什么?或者有更好的替代答案吗?

Question

最近我一直忙着在我的linux操作系统上玩bash，我也用它来排序文件。但这似乎并不奏效。我所做的事情是否有其他的替代方式，或者这是错误的?

echo -n "Are you sure you would like to delete this/these files? [y/n]"
if [ $answer == "y" ]; then
echo -n "Which File would you like to delete?"
rm $answer
else
echo "canceled!"
fi

Answer 1

检查"read"的用法命令

read -n1 -p "Are you sure you would like to delete this/these files? [y/n]: " answer
if [ "$answer" == "y" ]; then
read -p "Which File would you like to delete: " filename
rm $filename
else
echo "cancelled!"
fi
