Powershell 脚本计划任务输出到日志文件 [英] Powershell script scheduled task output to log file

问题描述

我有一些带有 Write-Host 的 Powershell 脚本，但我想将其用作计划任务.

I have Powershell script with some Write-Host but I want to use it as scheduled task.

我将其添加为计划任务:

I added it as scheduled task with this:

$action  = New-ScheduledTaskAction -Execute "$pshome\powershell.exe -WindowStyle Hidden" -Argument "-File $FilePath"
$trigger = New-ScheduledTaskTrigger -Once -At (Get-Date).Date -RepetitionInterval $repeat
Register-ScheduledTask -TaskName $Name -Trigger $trigger -RunLevel Highest -Action $action

我可以让它写入日志文件吗?是否可以将其写入与 Powershell 脚本相同位置的文件?

Can I make it write to log file? Is it possible to make it write to file at the same location as the Powershell script?

推荐答案

脚本有 2 个问题，第一个是我的主要问题:

There were 2 problems with the script and the 1st was my main problem:

1. 如果它未签名，则默认行为将被任务计划程序跳过(或者至少我没有在事件查看器中看到错误).
2. 我不得不使用写输出

检查脚本是否使用 签名获取 AuthenticodeSignature.在这里，您将收到 SignatureStatus 作为字符串:

---

Check if the script is signed with Get-AuthenticodeSignature. Here you are going to receive SignatureStatus as string:

$isSigned = Get-AuthenticodeSignature -FilePath $FilePath | select -ExpandProperty Status

如果它没有签名，你可以通过添加 -ExecutionPolicy Bypass 来启用它的执行，就像在这个 spiceworks 操作方法.为了安全起见，为您自己的脚本执行此操作！

If it is not signed, you can enable the execution of it by adding -ExecutionPolicy Bypass like it is described in this spiceworks how-to. Do this for your own scripts, because of security !

对于写作部分，我使用了 Write-输出和外文件:

For the writing part I used Write-Output and Out-File:

(
   ...
   Write-Output "some text here"
   ...
) | Out-File -FilePath "C:\somepath\log.log
