如何读取从批处理文件注册表字符串值 [英] how to read registry string value from batch file

问题描述

我想读注册表字符串值，从bat文件，然后assing的readed值变量。
我试过如下：

I want to read registry string value, from bat file, and then assing the readed value to variable. I tried the following :

FOR  %%a in ('REG QUERY HKLM\SOFTWARE\MathWorks\MATLAB\7.10 /v MATLABROOT') DO set MATLAB=%%a
echo %MATLAB% 

，但它不工作

推荐答案

如果该值（在这种情况下，巴兹）的名称不包含空格，你可以这样做

If the name of the value (baz in this case) does not contain spaces you can do something like

FOR /F "skip=4 tokens=2,*" %%A IN ('REG.exe query "HKLM\software\foo\bar" /v "baz"') DO set "MATLABROOT=%%B"

如果名称是动态的，只在运行时已知的，你将不得不使用代币= *和解析%%一个寻找REG_，让你知道数据开始的地方...

If the name is dynamic and only known at run time, you would have to use tokens=* and parse %%A looking for "REG_" so you know where the data starts...
