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。

基于@John Rees的回答，并做了一些改进。

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
        }
    }
}

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

受上面@john-rees的启发，我采取了另一种方法——尤其是当他的方法在某种程度上开始对我失败时。基本上递归的子树和排序文件的路径长度-删除从最长到最短

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，这里有另一个可能困扰你的问题:https://superuser.com/q/212808

当使用简单的删除项“文件夹”递归删除文件时，我有时会看到一个间歇性错误:[文件夹]不能删除，因为它不是空的。

这个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 - descent对所有项进行排序，以便在根项之前删除叶项。排序是在pspath参数上完成的，因为它更有可能用于提供程序而不是文件系统。如果您想筛选要删除的项，则-Include参数只是一种方便。

它分为两个函数，因为我发现它可以通过运行来查看我将要删除的内容

Get-Tree some_dir | select fullname
2012-07-17 10:24:28

如果你致力于powershell，你可以使用这个，正如在接受的答案中解释的那样:

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立即开始删除文件(powershell首先执行一些枚举)，因此如果在运行时出现故障，您至少在删除文件方面取得了一些进展。
