使用PowerShell脚本查找和替换具有特定扩展名的所有文件 [英] PowerShell Script to Find and Replace for all Files with a Specific Extension

问题描述

我在Windows Server 2008上有几个配置文件，像这样嵌套：

pre code C：\Projects\Project_1\ project1.config

C：\Projects\Project_2\project2.config

 < add key =Environmentvalue =在我的配置中我需要做一个字符串替换， 开发/> 
  

会变成：

 < add key =Environmentvalue =Demo/> 
  

我想过使用批处理脚本，但没有好的办法来做到这一点，我听说使用PowerShell脚本，您可以轻松执行此操作。我找到了find / replace的例子，但是我希望能够遍历C：\Projects目录下的所有文件夹，并找到任何以.config扩展名结尾的文件。当它找到一个，我希望它取代我的字符串值。

有什么好的资源来找到如何做到这一点或任何PowerShell的大师，可以提供一些洞察力？ / p>

解决方案

这里首先尝试一下我的头脑。

  $ configFiles = Get-ChildItem。 * .config -rec 
 foreach（$ configFiles中的$文件）
 {
（Get-Content $ file.PSPath）| 
 Foreach-Object {$ _ -replaceDev，Demo} | 
 Set-Content $ file.PSPath 
} 
  

I have several configuration files on Windows Server 2008 nested like such:

C:\Projects\Project_1\project1.config

C:\Projects\Project_2\project2.config

In my configuration I need to do a string replace like such:

<add key="Environment" value="Dev"/>

will become:

<add key="Environment" value="Demo"/>

I thought about using batch scripting, but there was no good way to do this, and I heard that with PowerShell scripting you can easily perform this. I have found examples of find/replace, but I was hoping for a way that would traverse all folders within my C:\Projects directory and find any files that end with the '.config' extension. When it finds one, I want it to replace my string values.

Any good resources to find out how to do this or any PowerShell gurus that can offer some insight?

解决方案

Here a first attempt at the top of my head.

$configFiles = Get-ChildItem . *.config -rec
foreach ($file in $configFiles)
{
    (Get-Content $file.PSPath) |
    Foreach-Object { $_ -replace "Dev", "Demo" } |
    Set-Content $file.PSPath
}
