schtasks不运行脚本

Question

在powershell中(不管是不是管理员)，C:\Users\mine\Desktop\LOL\test.ps1在没有schtasks的情况下可以正常工作，但是当我用它创建schtasks时，它就不能工作了。什么都没发生。

test.ps1可以在powershell中正常运行。

当我查询schtasks时，"Backup DB“显示状态为ready。

假设我将其设置为10:08。当我在10:08之前查询时，下一个运行时是今天的10:08。当我查询10:08之后，下一个运行时间是tomorrow 10:08，但是在两者之间没有发生任何事情。

PS C:\Users\mine> Schtasks /create /tn "Backup DB" /sc daily /st 10:08 /tr "C:\Users\mine\Desktop\LOL\test.ps1"
WARNING: The task name "Backup DB" already exists. Do you want to replace it (Y/N)? y
SUCCESS: The scheduled task "Backup DB" has successfully been created.

简而言之，我希望每天使用powershell运行我的test.ps1

您的任务创建很好。因为您没有调用powershell.exe来调用.ps1，所以从技术上讲，它只像记事本文件一样调用.ps1。

                $TaskName = "Backup DB"
                $TaskDescr = "Automated Backup DB"
                $TaskCommand = "c:\windows\system32\WindowsPowerShell\v1.0\powershell.exe"
                $TaskScript = '"C:\Users\mine\Desktop\LOL\test.ps1"+'"'
                $TaskArg = "-Executionpolicy unrestricted -file $TaskScript"


                        $service = new-object -ComObject("Schedule.Service")
                        # connect to the local machine.

                        $service.Connect()
                        $rootFolder = $service.GetFolder("\")
                        $TaskDefinition = $service.NewTask(0)
                        $TaskDefinition.RegistrationInfo.Description = "$TaskDescr"
                        $TaskDefinition.Settings.Enabled = $true
                        $TaskDefinition.Settings.AllowDemandStart = $true
                        $TaskDefinition.Settings.StartWhenAvailable = $true
                        $TaskDefinition.Settings.StopIfGoingOnBatteries=$false
                        $TaskDefinition.Settings.DisallowStartIfOnBatteries=$false
                        $TaskDefinition.Settings.MultipleInstances=2
                        $taskdefinition.Settings.WakeToRun=$true
                        $triggers = $TaskDefinition.Triggers
                        $trigger = $triggers.Create(1) # Creates a "One time" trigger
                        $trigger.StartBoundary = $TaskStartTime.ToString("yyyy-MM-dd'T'HH:mm:ss")
                        $time_interval=New-TimeSpan -Minutes $interval
                        $time_interval=$time_interval.TotalSeconds
                        $trigger.Repetition.Interval= "PT"+"$time_interval"+"S"
                        $trigger.Enabled = $true
                        $TaskDefinition.Principal.RunLevel =1
                        $Action = $TaskDefinition.Actions.Create(0)
                        $action.Path = "$TaskCommand"
                        $action.Arguments = "$TaskArg"
                        # In Task Definition,
                        #   6 indicates "the task will not execute when it is registered unless a time-based trigger causes it to execute on registration."
                        #   5 indicates "Indicates that a Local System, Local Service, or Network Service account is being used as a security context to run the task.In this case, its the SYSTEM"
                        $rootFolder.RegisterTaskDefinition("$TaskName",$TaskDefinition,6,"System",$null,5) | Out-Null

我已经添加了相应的注释来创建相应的任务和触发器。

的替代方法是直接使用Powershell，如下所示：

Import-Module TaskScheduler $task = New-Task
$task.Settings.Hidden = $true
Add-TaskAction -Task $task -Path C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe –Arguments “-File C:\Users\mine\Desktop\LOL\test.ps1”
Add-TaskTrigger -Task $task -Daily -At “10:06”
Register-ScheduledJob –Name ”Monitor Group Management” -Task $task

直接方法：

C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe -NoLogo -NonInteractive -File "C:\Users\mine\Desktop\LOL\test.ps1" 

希望能有所帮助。
