更多Bash选项菜单选项

我怎样才能有更多的选择来回答这个问题

while [ "$yn" != "Yes" ]; do
 echo "Please enter your Host Name"
 read hname
 echo "You have entered $hname, is this correct? (Yes or No)"
  read yn
done
sh runscript.sh

如果要回答“是”“是”“Y”或“Y”，如何才能做到这一点？ 提前感谢,，

与其他语言一样，Bash也有逻辑运算符。您可以使用Bash创建如下内容（这是伪代码）：

我建议你查阅Bash教程，你会发现更多！

干杯。

修好了！我认为这样做效果最好：

while [[ "$yn" != "Yes" && "$yn" != "Y" && "$yn" != "y" && "$yn" != "yes" ]]; do

耶

while [[ "$yn" != "Yes" && "$yn" != "Y" && "$yn" != "y" && "$yn" != "yes" ]]; do

while [ -z "$yn" ]
do
    read -p "Please enter your Host Name" hname
    read -p "You have entered $hname, is this correct? (Yes or No)" yn
    case $yn in
        Y|y|Yes|yes);;    # this is a no-op
        *) unset yn;;
    esac
done
