批处理文件-reg查询-获取和比较值 [英] Batch File - reg query - get and compare values

问题描述

大家好，

我正在尝试编写一个批处理文件，以检查是否安装了.NET 3.5.我知道运行以下命令会产生结果:

Hi all,

I am trying to write a batch file that checks if .NET 3.5 is installed. I know that running the following command produces the result:

reg query "HKEY_Local_Machine\Software\Microsoft\NET Framework Setup\NDP\v3.5" /v Install

但是，如何获取值(0或1)并在if语句中使用它，以便知道是否要安装.NET?

提前非常感谢.
亲切的问候，

But how can I get hold of the value (0 or 1) and make use of it in an if statement, so that I know whether to install .NET or not?

Many thanks in advance.
Kind regards,

推荐答案

嗨Programm3r，

我现在正在使用Ubuntu进行答复，所以我现在无法对其进行测试，但是您正在寻找的东西是这样的:

Hi Programm3r,

I''m answering using Ubuntu right now so I couldn''t test it right now but what you''re looking for is something like:

For /F %%A In (''reg query "HKEY_Local_Machine\Software\Microsoft\NET Framework Setup\NDP\v3.5" /v Install'') do goto skip

Echo reg value not found 

goto done

:skip

Echo reg value found 

:done

祝你好运！

Good luck!
