错误与bash的变量Linux的鞭尾/对话框参数 [英] Error with Linux whiptail/dialog arguments from bash variable

问题描述

有人能解释为什么code以下无法正常工作？我要疯了试图找出。

could someone explain why the code below doesn't work? I'm going crazy trying to find out.

#!/bin/bash

TEST="M1 \"1-wire Interface\" ON"
echo $TEST
RESULT=$(dialog --title "Config Modules State" --checklist "Choose modules to activate" 20 50 1 $TEST)

这本打印的输出，符合市场预期：

It prints this at the output, as expected:

M11线接口

对话给出了一个错误说：

'dialog' gives an error saying:

错误：预计3个参数，发现只有1

Error: Expected 3 arguments, found only 1.

鞭尾'不给任何错误，但刚刚上市退出其选项。

'whiptail' doesn't give any error but just exits listing out its options.

如果我是采取该字符串，它的印刷，复制和粘贴像这样在命令行上，它的工作原理：

If I were to take the string that it printed, copy and paste it like this on the command line, it works:

对话框--title配置模块状态--checklist选择模块激活20 50 1 M11线接口

dialog --title "Config Modules State" --checklist "Choose modules to activate" 20 50 1 M1 "1-wire Interface" ON

既对话和鞭尾。
这是怎么回事？

with both 'dialog' and 'whiptail'. What is going on?

系统：

• Linux的树莓派3.18.11+＃781 preEMPT


• 鞭尾（蝾螈）：0.52.14


• 对话框版本：1.1-20120215

推荐答案

从意见的答案，如果有人遇到这一点。

The answer from the comments if somebody comes across this.
