如何使用PowerShell查找和取消打开文件的文件共享会话

Question

当我们将更改推送到文件共享时，有时用户会打开应用程序，从而使文件无法从共享中打开-该文件已被锁定，我们无法替换它。 我想在覆盖文件之前在PowerShell脚本中找到与此类文件相对应的共享会话，并杀死它们（这是只读文件，主要是.DLL文件）。

这与查找“共享文件夹” MMC中打开的文件，然后在此处关闭相应的会话相同，但是我需要以编程方式和远程方式对多台服务器进行操作。

除了新的Powershell 4.0 / Win2012 cmdlet之外，我找不到其他任何东西，因此我编写了自己的脚本，我认为值得分享：

# Use "net files" to get the ID's of all files and directories on this computer 
# that are being accessed from a network share.
$openFiles = net files | 
    where { $_ -match "^(?<id>\d+)" } | 
    foreach {
        # Use "net files <id>" to list all information about this share access as a key/value list, and 
        # create a new PSObject with all this information in its properties.
        $result = new-object PSObject
        net files $matches["id"] | 
            where { $_ -match "^(?<key>.*[^\s])\s{2,}(?<value>.+)$" } | 
            foreach { 
                Add-Member -InputObject $result -MemberType NoteProperty -Name $matches["key"] -Value $matches["value"] 
            }
        return $result
    }

# Now that we know everything that's being accessed remotely, close all that 
# apply to our application folder.
$openFiles | 
    where { $_.Path -like "C:\MySharedFolder\MyApp*" } | 
    foreach { net files ($_."File Id") /close }

净文件/ close有什么问题？
