使用 Powershell 创建任务

Question

Good Afternoon:

I have written a PS Script that can create a task on my local machine; however, it is my intention to have this configure a task on multiple machines from a list. I cannot seem to find a way on how to do this. I did see something on using New-CimSession, but I dont think that is what I am looking for...

Here is my script:

foreach ($confighost in (Get-Content -Path "C:\Users\*User*\Documents\Test.txt"))
{
#Check for existent script in Task Scheduler

$taskpath = "\\$confighost\c$\Windows\System32\Tasks\LocalUserCleanUp"
$testtask = Test-Path -path $taskpath

If ($testtask -eq $true)
    {

        #If Task is already present, Do Not Run

        Write-Host "CleanUp Task Listed in Task Scheduler On" $confighost ". Will not Implement Task..."

    }

else
    {

        #If Task Does Not Exist Create Task
        New-CimSession -ComputerName $confighost
        Write-Host "No CleanUp Task Listed in Task Scheduler, Creating Task..."
        $action = New-ScheduledTaskAction -Execute 'Powershell.exe' -Argument "C:\Users\*Users*\Documents\ProfileCleanup.ps1"
        $trigger = New-ScheduledTaskTrigger -Daily  -At 2am
        $settings = New-ScheduledTaskPrincipal -UserId "SYSTEM" -LogonType ServiceAccount -RunLevel Highest
        Register-ScheduledTask -Action $action -Trigger $trigger -Principal $settings -TaskName "LocalUserCleanUp" -Description "Checks user accounts nightly to see if they are older than 30 days"

    }
} 

I look forward to your insight. Thanks again for all your assistance!

You can use Invoke-Command to execute your task creation code on a target server:

$cred = Get-Credential # There are a number of methods to automate reading the credential from a file
Invoke-Command -Credential $cred -ComputerName server01, server02, server0X {
  # Your task creation code here
}

If you have any variables defined in your local session that you need available in the remote code, you can reference them in your Invoke-Command ScriptBlock reference the variable from the using scope by prefixing the local variable with $using: .
