任务计划程序 Powershell 不会写入文件

Question

我有一个 powershell 脚本，用于通过计划任务触发和运行日志记录。问题是脚本在运行时不会以这种方式写入文件。如果我运行它通过 cmd 它完美地工作。我已尝试为脚本提供最高权限，并且在运行脚本时将日志文件的确切位置作为参数传递。都没有解决问题。请问有人可以帮忙吗？见代码：

Param([string]$inputPath, [string]$logfilelocation)

$i=0

$paths = Get-Content $inputPath;  #Text file with list of file paths to monitor
$global:Logfile = $logfilelocation

foreach ($path in $paths)  
{ 
    $filter = '*.*'  # You can enter a wildcard filter here. 

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

    # Here, all four events are registerd. You need only subscribe to events that you need: 
    #File Created
    Register-ObjectEvent $fsw Created -SourceIdentifier "$i+FileCreated" -Action { 
        $name = $Event.SourceEventArgs.Name 
        $changeType = $Event.SourceEventArgs.ChangeType 
        $timeStamp = $Event.TimeGenerated
        $username = F:\FTU-E2\PsLoggedon.exe -l 
        Write-Host "The file '$name' was $changeType by $username" -fore green 
        Out-File -FilePath $global:Logfile -Append -InputObject "The file '$name' was $changeType at $timeStamp by $username" -Force
    } 

    ++$i
}

while($true){
    start-sleep -second 5
}

命令：

Powershell.exe Add arguments: -ExecutionPolicy Bypass F:\FTU-E2\Scripts\monitor.ps1 -inputPath F:\FTU-E2\RejectPaths.txt -logfilelocation "F:\FTU-E2\Log.txt"

Answer 1

如果任务设置为 SYSTEM 帐户下的运行，或者实际上是您帐户以外的任何帐户，它会在 $username = F:\FTU-E2\PsLoggedon.exe -l 处挂起，因为 PsLoggedon 正在等待用户接受EULA，它在用户第一次运行将它放在机器上时出现。

您可以使用 -accepteula 命令绕过 EULA：

$username = C:\temp\PsLoggedon.exe -l -accepteula

进行此更改后，运行无论是使用我的帐户还是 SYSTEM 帐户将任务设置为运行都没问题。

此外，您可以删除脚本底部的无限循环，并在 PowerShell 命令上使用 -NoExit 开关，这样进程就不会结束。

 -ExecutionPolicy Bypass -NoExit ...
