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

要删除包括文件夹结构在内的完整内容使用

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

在remove-item中添加的-递归确保交互式提示被禁用。

我使用:

rm -r folderToDelete

这对我来说就像一个咒语(我从Ubuntu偷来的)。

在PowerShell $profile中添加一个自定义函数:

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

这是rm -rf行为最准确的表示。

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

基于@John Rees的回答，并做了一些改进。
