Bash确认输入或重新输入

我有一个非常简单的BASH脚本，询问用户是否希望输入一些输入。响应为

y

或

n

如果他们输入

n

，脚本将退出

如果他们输入

y

，则会询问他们一些问题。最后，我想让他们确认输入

如果是正确的，我们将继续，如果不是，我想返回问题，重新输入信息

到目前为止，我已经：

while true; do
    echo -e "Enter details ? "
    read yn
    case $yn in
        [Nn]* ) exit;;
        [Yy]* ) 
            echo -e "description"
            read desc

            echo -e "Address"
            read address

        * ) echo "Please answer yes or no.";;
    esac
done

这似乎很好，所以我试着添加确认。。但这不起作用

while true; do
    echo -e "Enter details ? "
    read yn
    case $yn in
        [Nn]* ) exit;;
        [Yy]* ) 
            echo -e "description"
            read desc

            echo -e "Address"
            read address

            echo -e "$desc - $address"

            while true; do
                echo -e "\nAre these details correct ? "
                read conf
                case $conf in
                    [Nn]* ) // return to enter details //
                    [Yy]* ) // carry on with the details entered // break;;
                esac
            done


        * ) echo "Please answer yes or no.";;
    esac
done

目的如下

用户选择

y

并输入描述和地址。该页面向他们显示了他们输入内容的摘要，并询问他们

这些详细信息是否正确？

如果正确，我们继续，脚本继续。输入错误，然后脚本返回它们以输入描述，然后输入地址

有人能建议怎么做吗。

谢谢

您可以再添加一个循环级别，并使用可选级别指示器

break[n]

：

while true; do
    echo -e "Enter details ? "
    read yn
    case $yn in
        [Nn]*) exit;;
        [Yy]*)
            while true; do
                echo -e "description"
                read desc

                echo -e "Address"
                read address

                echo -e "$desc - $address"

                while true; do
                    echo -e "\nAre these details correct ? "
                    read conf
                    case $conf in
                        [Nn]* ) break 1;;
                        [Yy]* ) break 3;;
                    esac
                done
            done;;
        *) echo "Please answer yes or no.";;
    esac
done

不要为此使用

案例

。 为您编写的脚本示例：

#!/bin/bash

while true; do
    echo -e "Enter details ?(y/n)"
    read yn
    if [[ $yn == "y" ]];then
            echo -e "description"
            read desc

            echo -e "Address"
            read address

            echo -e "$desc - $address"

            while true; do
                echo -e "\nAre these details correct ? (y/n)"
                read conf
                if [[ $conf == "y" ]];then
                    echo "All done"
                    break
                elif [[ $conf == "n" ]];then
                    break
                else
                    continue
                fi
            done
    elif [[ $yn == "n" ]];then
        break
    else
        continue
    fi

好了：

DONE=""
while [ "$DONE" != "true" ]; do
    echo -e "Enter details ? "
    read yn
    case $yn in
        [Nn]* ) exit;;
        [Yy]* )
            echo -e "description"
            read desc

            echo -e "Address"
            read address

            echo -e "$desc - $address"

            while true; do
                echo -e "\nAre these details correct ? "
                read conf
                case $conf in
                    [Nn]* )
                        break;;
                    [Yy]* )
                        echo "doing something with your values"
                        DONE="true"
                        break;;
                esac
            done
        ;;


        * ) echo "Please answer yes or no.";;
    esac
done

感谢我的理智，您能确认break1和break3的中断位置吗。

break1

与

break

相同：它退出最里面的循环<代码>中断3，在这种情况下退出最外层的循环。快速跟进此问题。如果他们回答“否”，则详细信息不正确，我们将返回循环，但如何用他们的最后一个答案自动填充问题？
