Create a scheduled task from Powershell

Create a recurring task

This will run every day at 5am. The $taskExists conditional is so that it can be overwritten if it already existed with the new settings.

$userName = "${env:computername}\Administrator"
$taskName = "RefreshSQLData"
$taskExists = Get-ScheduledTask | Where-Object {$_.TaskName -like $taskName }

echo $userName

if($taskExists) {
  Unregister-ScheduledTask -TaskName $taskName -Confirm:$False
}

$action = New-ScheduledTaskAction -Execute "n:\eaccountsRestApi\eMigrateToSql64.exe"
$trigger = New-ScheduledTaskTrigger -Daily -At 5am
$settings = New-ScheduledTaskSettingsSet -Hidden -AllowStartIfOnBatteries -DontStopIfGoingOnBatteries -StartWhenAvailable -RunOnlyIfNetworkAvailable
$principal = New-ScheduledTaskPrincipal -UserId ((Get-CimInstance –ClassName Win32_ComputerSystem | Select-Object -expand Name) + "\Administrator")
$task = New-ScheduledTask -Action $action -Trigger $trigger -Settings $settings -Principal $principal
Register-ScheduledTask $taskName -InputObject $task

Run it for one day at 5am every 30 minutes

$trigger = New-ScheduledTaskTrigger -Once -At 5am -RepetitionDuration  (New-TimeSpan -Days 1)  -RepetitionInterval  (New-TimeSpan -Minutes 30)

Register it as a user/password

Depending on the privilege of the user running the script, password may not be needed.

$task = New-ScheduledTask -Action $action -Trigger $trigger -Settings $settings
Register-ScheduledTask $taskName -InputObject $task -User $username -Password $password
