如何在Task Scheduler上執行PowerShell腳本？

Question

我試圖執行我的Powershell腳本以每5分鍾運行一次。 我嘗試使用Windows 7的Task Scheduler來運行它，但是它在記事本上打開了我的腳本，並且沒有在數據庫中插入任何內容

以下是我的Powershell V-2.0腳本。 我不確定代碼中是否有錯誤（對此表示懷疑），或者是否有辦法將其包含在腳本中以每5分鍾運行一次，可以說從上午9點到晚上9點。

這是我安排的時間：

General
--------
Run only when user is logged on

Triggers
--------
Trigger: at 8h56am every day- 
Details: After triggered, repeat every 5 minutes indefinitely
Status: Enabled

Actions
-------
Action: Start a program
Details: Path to the script

提前致謝！

Answer 1

計划任務的操作必須調用powershell.exe ，並將腳本文件作為參數傳遞。 參見http://blogs.technet.com/b/heyscriptingguy/archive/2012/08/11/weekend-scripter-use-the-windows-task-scheduler-to-run-a-windows-powershell-script.aspx

powershell.exe -file c:\path_to_your_script\script.ps1

執行腳本的用戶需要具有執行腳本中所有動作所需的權限。

Answer 2

沒有任務描述，這全都是猜測。 無論如何，聽起來您只指定了要運行的腳本，而不是執行引擎。 也就是說，任務計划程序將能夠運行.cmd和.bat腳本而無需任何額外的配置。 Powershell並非如此。 您必須指定任務以運行powershell.exe並將腳本文件的路徑作為參數傳遞。 一個簡單的示例在Technet中。

由於Powershell的.ps1與批處理不同的原因是安全性。 快速轉儲makse Powershell腳本並沒有使Powershell腳本易於運行，反而沒有吸引攻擊性。

Answer 3

嘗試使用此CMD包裝文件從任務計划程序啟動，然后將其命名為runYour-PS1-filename.cmd 。 該文件將創建一個錯誤日志和標准輸出日志：

@echo off
SetLocal
REM
REM This cmd file will launch it's corresponding PowerShell-script.

REM We need to change std character set to support international characters when calling
