Powershell脚本启动过程无效

标签： powershell cmdlets start-process

我的脚本出现问题，但找不到解决方法。总之，当我尝试运行这个脚本时，它说：

Cmdlet Start-Process an der Befehlspipelineposition 1   Geben SieWertefürdiefolgenden参数an：   文件路径：

这是什么意思？ 我知道我在Powershell中不是很好，去年夏天开始写剧本。 所以它可能看起来有点难看......

这是我的剧本，希望有人可以帮助我：

您可以试试这个吗？

$ps = new-object System.Diagnostics.Process
$ps.StartInfo.Filename = $utilityScript
$ps.StartInfo.RedirectStandardOutput = $True
$ps.StartInfo.UseShellExecute = $false
$ps.start()
$ps.WaitForExit()
$result = $ps.StandardOutput.ReadToEnd();

我建议你把它变成一个功能，所以你可以多次调用它。像这样：

function RunProcessWithOutput($fileName)
{
$ps = new-object System.Diagnostics.Process
$ps.StartInfo.Filename = $fileName
$ps.StartInfo.RedirectStandardOutput = $True
$ps.StartInfo.UseShellExecute = $false
$ps.start()
$ps.WaitForExit()
return $ps.StandardOutput.ReadToEnd();
}

并像这样打电话

$result = RunProcessWithOutput $utilityScript

这是结果

function RunProcessWithOutput($fileName)
{
$ps = new-object System.Diagnostics.Process
$ps.StartInfo.Filename = $fileName
$ps.StartInfo.RedirectStandardOutput = $True
$ps.StartInfo.UseShellExecute = $false
$ps.start()
$ps.WaitForExit()
return $ps.StandardOutput.ReadToEnd();
}

    $utilityScript = (Join-Path $thisScriptDirectoryPath $utilityScriptName)
    $result = RunProcessWithOutput $utilityScript
}

function Task_D{

    $thisScriptDirectoryPath = Split-Path -parent 
    $MyInvocation.MyCommand.Definition
    $utilityScriptName = "task_d.ps1"

我认为我喜欢这个解决方案。我刚刚更改了任务的功能，因此需要使用PS的路径。所以现在它看起来像这样：

$utilityScriptName = "..\start2.ps1"
$utilityScript = (Join-Path $PSCommandpath $utilityScriptName)
$result = .$utilityScript

这很有效，但我不知道这是否适用于其他脚本。谢谢你的帮助
