Question

我正在尝试创建一个bash脚本来捕获运行它的用户的输入。输入将沿目标和源目录的名称行。源目录的布局为每小时。＃，每日。＃和每月。＃。输入将像hourly.33一样捕获并更改到该目录以将该文件夹的所有内容复制到目标。总共有2个目的地可供选择，但有55个不同的来源。我没有使用以下内容包裹我的头：

#!/bin/bash
### Modify below this ###
srv1=/home/minecraft/test/rr1server2
srv2=/home/minecraft/test/rr2server2
srv3=/home/minecraft/test/rrlobby2
### DO NOT MODIFY BELOW THIS ###
while true; do
    read -p "Are you sure you want to start the rollback?:" yn
    case $yn in
        [Yy]* )
            while true; do
                read -p "Which server? 1, 2 or 3:" srv
                    case $srv in
                        [1]* )
                            while true; do
                                read -p "Which backup? Input only hourly.#, daily.# or monthly.#:" rollback
                                cd $rollback
                                cp -Rp * $srv1
                                echo "Rollback Complete!"; exit;;
                        [2]* )
                            while true; do
                                read -p "Which backup? Input only hourly.#, daily.# or monthly.#:" rollback
                                cd $rollback
                                cp -Rp * $srv2
                                echo "Rollback Complete!"; exit;;
                            esac
                        done
                        [3]* )
                            while true; do
                                read -p "Which backup? Input only hourly.#, daily.# or monthly.#:" rollback
                                cd $rollback
                                cp -Rp * $srv3
                                echo "Rollback Complete!"; exit;;
                            esac
                        done
                    exit;;
                esac
            done
        exit;;
    esac
done

我得到以下

minecraft@cronus:~/test$ ./rollback.sh
./rollback.sh: line 21: syntax error near unexpected token `;;'
./rollback.sh: line 21: `                                                               echo "Rollback Complete!"; exit;;'

我认为您已经发现，使用该程序的当前结构，调试变得越来越困难。

因此，我认为现在开始使用功能是不可思议的。这是你的程序吐出的功能，几乎所有的程序仍然是你的代码。

现在我担心新功能，但调试更容易:-)
（事实上，我发现了一些）

#!/bin/bash

RollBack()
{
    while :
    do
        read -p "Which backup? Input only hourly.#, daily.# or monthly.#:" rollback
        cd "$rollback"
        cp -Rp * "$1"
        echo "Rollback Complete!"
    done
}

WhichServer()
{
    read -p "Which server? 1, 2 or 3:" srv
    case "$srv" in
        [1]* ) RollBack "$srv1" ;;
        [2]* ) RollBack "$srv2" ;;
        [3]* ) RollBack "$srv3" ;;
    esac
}

while : 
do
    read -p "Are you sure you want to start the rollback?:" yn
    case "$yn" in
        [Yy]* ) while true; do WhichServer; done ;;
    esac
done

Bash捕获输入和cd到它
