如何递归删除一个完整的目录与PowerShell 2.0?

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PowerShell V2。

我从几个来源了解到，最明显的命令，Remove-Item $targetDir -Recurse -Force，不能正确工作。这包括PowerShell V2在线帮助中的语句(使用Get-Help Remove-Item -Examples找到)，声明:

.．.因为这个cmdlet中的递归参数是错误的，该命令使用get - childitem cmdlet来获取所需的文件，并使用管道操作符将它们传递给Remove-Item cmdlet…

我见过使用Get-ChildItem并将其输送到remove - item的各种示例，但这些示例通常基于过滤器删除一些文件集，而不是整个目录。

我正在寻找最干净的方法来吹出整个目录，文件和子目录，而不生成任何用户警告消息使用最少的代码量。如果简单易懂，那么一行代码最好。

当前回答

Remove-Item -Recurse -Force some_dir

确实像广告上说的那样有效。

rm -r -fo some_dir

速记别名也有用吗?

据我所知，当您尝试递归删除一组过滤过的文件时，-Recurse参数不能正确工作。杀死一个单一的目录和下面的一切似乎工作得很好。

其他回答

出于某种原因，约翰·里斯的回答有时对我不起作用。但它把我引向了下面的方向。 首先，我尝试使用buggy -recurse选项递归地删除目录。然后，我进入剩下的每个子目录并删除所有文件。

function Remove-Tree($Path)
{ 
    Remove-Item $Path -force -Recurse -ErrorAction silentlycontinue

    if (Test-Path "$Path\" -ErrorAction silentlycontinue)
    {
        $folders = Get-ChildItem -Path $Path –Directory -Force
        ForEach ($folder in $folders)
        {
            Remove-Tree $folder.FullName
        }

        $files = Get-ChildItem -Path $Path -File -Force

        ForEach ($file in $files)
        {
            Remove-Item $file.FullName -force
        }

        if (Test-Path "$Path\" -ErrorAction silentlycontinue)
        {
            Remove-Item $Path -force
        }
    }
}

另一个有用的技巧:

如果你发现很多文件有相同或相似的命名约定(比如mac文件用点前缀命名…你可以很容易地从powershell中删除它们，就像这样:

ls -r .* | rm

这一行将删除当前目录中名称开头带有点的所有文件，以及该目录中其他文件夹中具有相同情况的所有文件。使用时要注意。: D

在Windows上，Remove-Item -Force -Recurse可能会间歇性失败，因为底层文件系统是异步的。这个答案似乎解决了这个问题。该用户还积极参与GitHub上的Powershell团队。

2020-08-04 15:49:24 
del <dir> -Recurse -Force # I prefer this, short & sweet

OR

remove-item <dir> -Recurse -Force

如果你有一个很大的目录，那么我通常会做的是

while (dir | where name -match <dir>) {write-host deleting; sleep -s 3}

在另一个powershell终端上运行，当它完成时，它将停止。
