Question

我如何有更多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

想回答“是”“是”“Y”或“y”，怎么办？提前致谢，乔

Answer 1

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

Answer 2

与其他任何语言一样，Bash也有逻辑运算符。你可以用Bash创建这样的东西（这是伪代码）：

If answer equals "Yes", or answer equals "yes":
   bla bla

我建议你查找一个Bash教程，你会发现它还有更多！欢呼声。

修正了它！认为这最有效：

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

耶！
