如何使用Regex通过PowerShell从专有名称中仅提取CN [英] How can I use Regex to pull just the CN from a Distinguished Name with PowerShell

问题描述

我有一堆字符串，它们是AD中组的DN.我需要拔出通用名称". 一个示例字符串是"CN =我想要的组名，OU =组容器，DC = corp，DC = test，DC =本地"

I have a bunch of strings that are DN's of groups from AD. I need to pull out the Common Name. An example string is "CN=Group Name I Want,OU=Group Container,DC=corp,DC=test,DC=local"

我正在寻找的是一些PowerShell代码，该代码将从该字符串中提取我想要的组名"，并丢弃其余的代码.

What I am looking for is some PowerShell Code that will pull "Group Name I Want" out of that string and discard the rest.

我可以以此撕裂CN

$s = "CN=Group Name I Want,OU=Group Container,DC=corp,DC=test,DC=local"
$s = $s.Remove(0,3) 

但是在那之后，我没有一个很好的方法来摆脱以，OU"开头的所有内容

But after that, I don't have a good way to rip off everthing starting at ",OU"

我肯定会有一些正则表达式可以做到这一点，但是我需要一些帮助来弄清楚它.

I am sure there is some regex that will do this but I need some help figuring it out.

推荐答案

$s = "CN=Group Name I Want,OU=Group Container,DC=corp,DC=test,DC=local"
$s -replace "(CN=)(.*?),.*",'$2'
