批处理 - 指定命令输出变量 [英] Batch - Assign Command output to Variable

问题描述

我想一个命令的输出分配给一个变​​量 - 在，我想设置当前flash版本给一个变量。我知道这是错的，但是这是我试过：

I'm trying to assign the output of a command to a variable - as in, I'm trying to set the current flash version to a variable. I know this is wrong, but this is what I've tried:

组VAR =章查询HKLM \\ SOFTWARE \\ Macromedia的\\ Flash插件\\ CURRENTVERSION>

set var=reg query hklm\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion>

或

章查询HKLM \\ SOFTWARE \\ Macromedia的\\ Flash插件\\ CURRENTVERSION >>集VAR

reg query hklm\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion >> set var

是的，你可以看到我有点失落。任何及所有帮助AP preciated！

Yeah, as you can see I'm a bit lost. Any and all help is appreciated!

推荐答案

一个方法已经被设计出来，但是这样一来，你并不需要一个临时文件。

A method has already been devised, however this way you don't need a temp file.

for /f "delims=" %%i in ('command') do set output=%%i

不过，我敢肯定，这有它自己的例外和限制。

However, I'm sure this has its own exceptions and limitations.
