如何检查是否文件正被另一个进程 - 的Powershell

问题描述：

我试图找到一个解决方案，将检查文件是否正被另一个进程。我不想读文件的内容，作为一个7GB文件，这可能需要一段时间。目前我使用下面提到的功能，这是不理想的，因为剧本需要5 - 10分钟，检索值

I am trying to find a solution which will check whether a file is being used by another process. I don't want to read the contents of the file, as on a 7GB document, this could take a while. Currently I am using the function mentioned below, which is not ideal as the script takes about 5 - 10 minutes to retrieve a value.

function checkFileStatus($filePath)
{
    write-host (getDateTime) "[ACTION][FILECHECK] Checking if" $filePath "is locked"

    if(Get-Content $filePath  | select -First 1)
    {
        write-host (getDateTime) "[ACTION][FILEAVAILABLE]" $filePath
        return $true
    }
    else
    {
        write-host (getDateTime) "[ACTION][FILELOCKED] $filePath is locked"
        return $false
    }
}

任何帮助将大大AP preciated

Any help would be greatly appreciated

创建了一个功能，解决了上述问题：

Created a function which solves the above problem:

 function checkFileStatus($filePath)
    {
        write-host (getDateTime) "[ACTION][FILECHECK] Checking if" $filePath "is locked"
        $fileInfo = New-Object System.IO.FileInfo $filePath

        try 
        {
            $fileStream = $fileInfo.Open( [System.IO.FileMode]::Open, [System.IO.FileAccess]::Read, [System.IO.FileShare]::Read )
            write-host (getDateTime) "[ACTION][FILEAVAILABLE]" $filePath
            return $true
        }
        catch
        {
            write-host (getDateTime) "[ACTION][FILELOCKED] $filePath is locked"
            return $false
        }
    }
