将命令输出分配给批处理文件中的变量 [英] Assign Command output to Variable in Batch file

问题描述

我试图将一个命令的输出分配给一个变量，因为我试图将当前的Flash版本设置为一个变量。我知道这是错误的，但这是我已经试过：

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

或

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

是的，正如您所看到的我有点失落任何和所有的帮助，赞赏！

解决方案

一种方法已经被设计出来，然而这种方式你不需要临时文件

$ b $ pre $ for / fdelims =%% i in（'command'）do set output = %% i


但是，我确定这有它自己的例外和限制。

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:

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

or

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

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

解决方案

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

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