如何使用 PowerShell 2.0 递归删除整个目录？

Question

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。

我从多个来源了解到，最明显的命令Remove-Item $targetDir -Recurse -Force无法正常工作。 这包括 PowerShell V2 在线帮助（使用Get-Help Remove-Item -Examples ）中的声明：

...因为此 cmdlet 中的 Recurse 参数有问题，该命令使用 Get-Childitem cmdlet 获取所需文件，并使用管道运算符将它们传递给 Remove-Item cmdlet ...

我见过使用Get-ChildItem并将其通过管道传递给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清除整个目录、文件和子目录，而不会使用最少的代码生成任何用户警告消息。 如果易于理解，单线会很好。

Answer 1

Remove-Item -Recurse -Force some_dir

确实像这里宣传的那样工作。

rm -r -fo some_dir

是也有效的速记别名。

据我了解，当您尝试递归删除一组过滤的文件时， -Recurse参数无法正常工作。 对于杀死单个目录及其下面的所有内容似乎都可以正常工作。

Answer 2

我用了：

rm -r folderToDelete

这对我来说就像一个魅力（我从 Ubuntu 偷了它）。

Answer 3

使用简单的Remove-Item "folder" -Recurse递归删除文件时，我有时会看到间歇性错误： [folder] cannot be removed because it is not empty.

此答案试图通过单独删除文件来防止该错误。

function Get-Tree($Path,$Include='*') { 
    @(Get-Item $Path -Include $Include -Force) + 
        (Get-ChildItem $Path -Recurse -Include $Include -Force) | 
        sort pspath -Descending -unique
} 

function Remove-Tree($Path,$Include='*') { 
    Get-Tree $Path $Include | Remove-Item -force -recurse
} 

Remove-Tree some_dir

一个重要的细节是使用pspath -Descending对所有项目进行排序，以便在根之前删除叶子。 排序是在pspath参数上完成的，因为它有更多的机会为文件系统以外的提供者工作。 如果要过滤要删除的项目， -Include参数只是一种方便。

它分为两个功能，因为我发现通过运行查看我将要删除的内容很有用

Get-Tree some_dir | select fullname

Answer 4

rm -r ./folder -Force    

...为我工作

Answer 5

试试这个例子。 如果目录不存在，则不会引发错误。 您可能需要 PowerShell v3.0。

remove-item -path "c:\Test Temp\Test Folder" -Force -Recurse -ErrorAction SilentlyContinue

Answer 6

使用老式的 DOS 命令：

rd /s <dir>

Answer 7

出于某种原因，约翰·里斯的回答有时在我的情况下不起作用。 但它使我朝着以下方向前进。 首先，我尝试使用 buggy -recurse 选项递归删除目录。 之后，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
        }
    }
}

Answer 8

为避免已接受答案的“目录不为空”错误，只需按照之前的建议使用旧的 DOS 命令。 准备复制粘贴的完整 PS 语法是：

& cmd.exe /c rd /S /Q $folderToDelete

Answer 9

删除整个文件夹树有时会起作用，有时会因“目录非空”错误而失败。 随后尝试检查文件夹是否仍然存在可能会导致“拒绝访问”或“未经授权的访问”错误。 我不知道为什么会发生这种情况，尽管可以从这篇 StackOverflow 帖子中获得一些见解。

通过指定文件夹中项目的删除顺序和添加延迟，我已经能够解决这些问题。 以下对我来说运行良好：

# First remove any files in the folder tree
Get-ChildItem -LiteralPath $FolderToDelete -Recurse -Force | Where-Object { -not ($_.psiscontainer) } | Remove-Item –Force

# Then remove any sub-folders (deepest ones first).    The -Recurse switch may be needed despite the deepest items being deleted first.
ForEach ($Subfolder in Get-ChildItem -LiteralPath $FolderToDelete -Recurse -Force | Select-Object FullName, @{Name="Depth";Expression={($_.FullName -split "\\").Count}} | Sort-Object -Property @{Expression="Depth";Descending=$true}) { Remove-Item -LiteralPath $Subfolder.FullName -Recurse -Force }

# Then remove the folder itself.  The -Recurse switch is sometimes needed despite the previous statements.
Remove-Item -LiteralPath $FolderToDelete -Recurse -Force

# Finally, give Windows some time to finish deleting the folder (try not to hurl)
Start-Sleep -Seconds 4

Microsoft TechNet 文章在 PowerShell 中使用计算属性对我获取按深度排序的子文件夹列表很有帮助。

与RD /S /Q类似的可靠性问题可以通过在RD /S /Q之前运行DEL /F /S /Q并在必要时第二次运行RD来解决 - 理想情况下中间有暂停（即使用如图所示的ping以下）。

DEL /F /S /Q "C:\Some\Folder\to\Delete\*.*" > nul
RD /S /Q "C:\Some\Folder\to\Delete" > nul
if exist "C:\Some\Folder\to\Delete"  ping -4 -n 4 127.0.0.1 > nul
if exist "C:\Some\Folder\to\Delete"  RD /S /Q "C:\Some\Folder\to\Delete" > nul

Answer 10

del <dir> -Recurse -Force # I prefer this, short & sweet

或者

remove-item <dir> -Recurse -Force

如果你有一个巨大的目录，那么我通常做的是

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

在另一个 powershell 终端上运行它，它会在完成后停止。

Answer 11

如果您致力于使用 powershell，则可以使用它，如已接受的答案中所述：

rm -r -fo targetDir

但我发现使用 Windows 命令提示符更快

rmdir /s/q targetDir

除了速度更快之外，使用命令提示符选项的另一个优点是它会立即开始删除文件（powershell 首先进行一些枚举），因此如果在运行时出现问题，您至少在删除文件方面取得了一些进展。

Answer 12

另一个有用的技巧：

如果您发现许多具有相同或相似名称约定的文件（例如带有点前缀名称的 mac 文件...那个著名的文件提取），您可以像这样从 powershell 中使用一行轻松删除它们：

ls -r .* | rm

此行将删除当前目录中名称开头带点的所有文件，以及该目录中其他文件夹中所有情况相同的文件。 使用时请注意这一点。 :D

Answer 13

我采取了另一种受上述@john-rees 启发的方法 - 特别是当他的方法在某些时候开始对我失败时。 基本上递归子树并按路径长度对文件进行排序 - 从最长到最短删除

Get-ChildItem $tfsLocalPath -Recurse |  #Find all children
    Select-Object FullName,@{Name='PathLength';Expression={($_.FullName.Length)}} |  #Calculate the length of their path
    Sort-Object PathLength -Descending | #sort by path length descending
    %{ Get-Item -LiteralPath $_.FullName } | 
    Remove-Item -Force

关于 -LiteralPath 魔法，这里有另一个可能会打击你的陷阱： https ://superuser.com/q/212808

Answer 14

真的很简单：

remove-item -path <type in file or directory name>, press Enter

Answer 15

要删除包括文件夹结构在内的完整内容，请使用

get-childitem $dest -recurse | foreach ($_) {remove-item $_.fullname -recurse}

添加到remove-item的-recurse确保禁用交互式提示。

Answer 16

由于底层文件系统是异步的，似乎存在Remove-Item -Force -Recurse在 Windows 上间歇性失败的问题。 这个答案似乎解决了这个问题。 该用户还积极参与了GitHub 上的 Powershell 团队。

基于@John Rees的回答并进行了一些改进。

Answer 18

虽然 rm -r 产生良好的结果，但以下方法更快：

$fso = New-Object -ComObject scripting.filesystemobject
$fso.DeleteFolder("D:\folder_to_remove")

为了测试这一点，您可以轻松地创建一个包含 X 文件的文件夹（我使用：磁盘工具来快速生成文件）。

然后使用以下命令运行每个变体：

Measure-Command {rm D:\FOLDER_TO_DELETE -r}
Measure-Command {Remove-Item -Path D:\FOLDER_TO_DELETE -Recurse -Force}
Measure-Command {rd -r FOLDER_TO_DELETE }
$fso.DeleteFolder("D:\folder_to_remove")
Measure-Command {$fso.DeleteFolder("D:\FOLDER_TO_DELETE")}

我的测试文件夹上的结果是：

Remove-Item - TotalMilliseconds : 1438.708
rm - TotalMilliseconds : 1268.8473
rd - TotalMilliseconds : 739.5385
FSO - TotalMilliseconds : 676.8091

结果各不相同，但在我的系统上，获胜者是 fileSystemObject。 我建议在目标文件系统上测试这个，看看哪种方法最适合你。

Answer 19

在 PowerShell $profile添加自定义函数：

function rmrf([string]$Path) {
    try {
        Remove-Item -Recurse -ErrorAction:Stop $Path
    } catch [System.Management.Automation.ItemNotFoundException] {
        # Ignore
        $Error.Clear()
    }
}

这是rm -rf行为的最准确表示。

Answer 20

$users = get-childitem \\ServerName\c$\users\ | select -ExpandProperty name

foreach ($user in $users)

{
remove-item -path "\\Servername\c$\Users\$user\AppData\Local\Microsoft\Office365\PowerShell\*" -Force -Recurse
Write-Warning "$user Cleaned"
}

写上面的内容是为了在不删除父目录的情况下清理一些日志文件，这非常有效！

Answer 21

rm -r <folder_name>
c:\>rm -r "my photos"
