Question

我有以下的powershell脚本，不像我想的那样工作。我想将源文件夹（$ folder）中新创建的文件复制到我的目标文件夹（$ DestFolder），但不复制任何文件。有谁看到可能出错的地方？

$SourceFolder = 'd:\temp\' # Enter the root path you want to monitor.
$folder = 'd:\temp' # Enter the root path you want to monitor.
$Destfolder = 'd:\temp2\' # Enter the root path you want to monitor.
$global:MySourceFolder = 'd:\temp\' # Enter the root path you want to monitor.
$global:MyDestfolder = 'd:\temp2\' # Enter the root path you want to monitor.
$filter = '*.*'  # You can enter a wildcard filter here.

# In the following line, you can change 'IncludeSubdirectories to $true if required.                          
$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property @{IncludeSubdirectories = $false;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'}


Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
$name = $Event.SourceEventArgs.Name
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
#Write-Host "The file '$name' was $changeType at $timeStamp" -fore green
Write-Host "path :  $MyDestfolder$name" -fore green
Copy-Item (Join-Path $MySourceFolder $name) ($Destfolder)
Out-File -FilePath d:\temp\filechange\outlog.txt -Append -InputObject "The file '$name' was $changeType at $timeStamp"}

我相信它按预期工作。如果副本实际上是操作的一部分，请尝试在动作脚本块中移动该行。

变量$ name在action scriptblock之外是空的，因为ObjectEvent有自己的范围。如果需要从Action scriptblock外部访问此变量，可以使用$ global：name。

声明变量

以下内容确实应该可以使用（替换为此但保存代码副本，以便首先获得备份）

$folder = 'd:\temp'
$Destfolder = 'd:\temp2'
$filter = '*.*'

$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property @{ 
    IncludeSubdirectories = $false
    NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'
}

Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
    $name = $Event.SourceEventArgs.Name
    $changeType = $Event.SourceEventArgs.ChangeType
    $timeStamp = $Event.TimeGenerated

    Write-Host "The file '$name' was $changeType at $timeStamp" -fore green
    Copy-Item -Path (Join-Path $folder $name) -Destination $Destfolder
    Out-File -FilePath "d:\temp\filechange\outlog.txt" -Append -InputObject "The file '$name' was $changeType at $timeStamp"
}

PowerShell中的副本无法按预期工作
