bash - 使用案例陈述创建菜单

问题描述

制作了一个请求用户正确密码（qwerty）的脚本，比较文本文件中的哈希值。参考该脚本，我必须在选择 1-7 和 8 退出时加载的其他文件夹中制作一组项目以供选择。鉴于我的评论，已经尝试了很多，但无法使其正常工作。谢谢。

#!/bin/bash

#ReadMe=`cat PasswordCheck.sh`
#echo "$ReadMe"

#read -sp 'PasswordCheck.sh'

解决方案

您脚本的密码检查部分对我来说仍然很模糊，但是我可以帮助您解决菜单问题。
选择可能是您设置选择菜单所需的。
下面是一个 sceleton 脚本，您可以根据需要进行扩展：

#!/bin/bash
function menu() {
        options=("Create_a_folder" "Copy_a_folder" "Set_a_password" "Calculator" "Create_Week_Folders" "Check_Filenames" "Download_a_File" "exit")
        echo "Choose option:" 1>&2
        select opt in ${options[@]}; do
        case ${REPLY} in
                *) choice="${options[$(( $REPLY - 1 ))]}"; break;;
        esac
        done
        echo "$choice"
}

#passwordcheck=`somefunction`
passwordcheck=true    # replace this once your function is ready
if [ "$passwordcheck" == "true" ]; then
        choice=`menu`
        [[ "$choice" == "exit" ]] && exit
        echo "You have chosen: $choice"
fi
