如何使用PowerShell 2.0递归删除整个目录？ [英] How to recursively delete an entire directory with PowerShell 2.0?

问题描述

在PowerShell中强制删除目录及其所有子目录的最简单方法是什么？我在Windows 7中使用了PowerShell V2。

我从几个来源得知，最明显的命令是 Remove-Item $ targetDir -Recurse - 强制，无法正常工作。这包括PowerShell V2联机帮助（使用 Get-Help Remove-Item -Examples 找到）中的一条语句：

...因为此cmdlet中的Recurse参数有错误，所以该命令使用Get-Childitem cmdlet获取所需的文件，并使用管道运算符将它们传递给Remove- Item cmdlet ...

我已经看到了各种使用 Get-ChildItem 的例子， strong> Remove-Item ，但这些示例通常会删除基于过滤器的一些文件，而不是整个目录。

我正在寻找最干净的方式吹出一个完整的目录，文件和子目录，而不用用最少量的代码生成任何用户警告消息。如果这很容易理解，那么一行就好。

解决方案

  Remove- Item -Recurse -Force some_dir 
  

确实可以在这里做广告。

据我了解，当您尝试递归删除一组已过滤的文件时， -Recurse 参数就无法正常工作。杀死一个单独的目录和下面的一切似乎工作正常。

What is the simplest way to forcefully delete a directory and all its subdirectories in PowerShell? I am using PowerShell V2 in Windows 7.

I have learned from several sources that the most obvious command, Remove-Item $targetDir -Recurse -Force, does not work correctly. This includes a statement in the PowerShell V2 online help (found using Get-Help Remove-Item -Examples) that states:

...Because the Recurse parameter in this cmdlet is faulty, the command uses the Get-Childitem cmdlet to get the desired files, and it uses the pipeline operator to pass them to the Remove-Item cmdlet...

I have seen various examples that use Get-ChildItem and pipe it to Remove-Item, but the examples usually remove some set of files based on a filter, not the entire directory.

I am looking for the cleanest way to blow out an entire directory, files and child directories, without generating any user warning messages using the least amount of code. A one-liner would be nice if it is easy to understand.

解决方案

Remove-Item -Recurse -Force some_dir

does indeed work as advertised here.

As far as I understood it, the -Recurse parameter just doesn't work correctly when you try deleting a filtered set of files recursively. For killing a single dir and everything below it seems to work fine.
