将特殊字符从一个批处理文件写入另一个 [英] Writing special characters from one batch file to another

问题描述

我正在尝试使用echo从另一个批处理文件写入一个批处理文件.但是，只有一行带有特殊字符，我无法弄清楚该怎么写.

I am trying to write one batch file from another, using echo. However, there is one line with special characters that I cannot work out how to write.

我有以下一行:

echo >nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system" >> "c:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\OrchestrationCleanUp.bat"

但是写入目标文件的是:

But what gets written to the target file is:

 "C:\Windows\system32\cacls.exe" "C:\Windows\system32\config\system" 

应该是:

>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"

我尝试将其用双引号引起来.

I have tried putting it in double quotes.

我尝试过将^放在>

我尝试将其放在变量中并用双引号转义

I have tried putting it in a variable and escaping it with double quotes

我尝试将其放在变量中并使用！在每一端

I have tried putting it in a variable and using ! at each end

我尝试将其放在变量中，并在变量名的末尾使用:.

I have tried putting it in a variable and using a : at the end of the variable name.

推荐答案

特殊字符需要使用^进行转义，并且%符号必须加倍.试试这个:

The special characters need to be escaped with ^ and % signs have to be doubled. Try this:

回显后的(会立即停止某些前导字符的问题.

The ( directly after echo stops issues with some leading characters.

echo(^>nul 2^>^&1 "%%SYSTEMROOT%%\system32\cacls.exe" "%%SYSTEMROOT%%\system32\config\system" >> "c:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\OrchestrationCleanUp.bat"
