Scheduled Tasks in Powershell, Alpha

Posted on by

Scheduled tasks don’t have any good way to be edited in Powershell, at least from what I have seen. The other day I set out to write some scripts to help me out. This isn’t really cleaned up or final (aka I haven’t figured out the best error checking yet and it could use a decent refactoring), but I figured I would go ahead and throw them up here to get some feedback.

 
function get-scheduledtask($server=$env:COMPUTERNAME)
{
	$tempFile = $env:TEMP + "\scheduledtaskstemp.csv"
	schtasks /query /S $server /FO csv /V | where { $_.length -gt 0 } | Set-Content $tempFile
	Import-Csv $tempFile
	Remove-Item $tempFile
}
 
function remove-scheduledtask($taskname, $server=$env:COMPUTERNAME, [switch]$verbose, [switch]$whatif=$variable:whatifpreference)
{
	if(-not $taskname) { throw "Must provide taskname" }
	$command = "schtasks /DELETE /TN '$taskName'"
	if($server) { $command += " /S '$server' " }
 
	if($verbose -or $whatif) { $command }
	if(-not $whatif) { Invoke-Expression $command }
}
 
function run-scheduledtask($taskname, $server=$env:COMPUTERNAME, [switch]$verbose, [switch]$whatif=$variable:whatifpreference){
	if(-not $taskname) { throw "Must provide taskname" }
	$command = "schtasks /RUN /TN '$taskname'"
 
	if($server) { $command += " /S '$server' " }
 
	if($verbose -or $whatif) { $command }
	if(-not $whatif) { Invoke-Expression $command }
}
 
function add-scheduledtask {
	param
	(
		[string] $user, 
		[string] $password, 
		[string] $schedule,
		[string] $runUser,
		[string] $runPassword,
		$modifier, 
		$days, 
		$idleTime, 
		$taskName, 
		$taskRun, 
		$startTime, 
		$months, 
		$startDate, 
		$endDate, 
		$server=$env:COMPUTERNAME,
		[switch]$verbose,
		[switch]$whatif = $variable:whatifpreference
	)	
 
	if(-not $taskName) { throw "Must Provide a taskName" }
	if(-not $taskRun) { throw "Must provide a taskRun" }
	if(-not $schedule) { throw "Must provide a schedule" }
	if(-not $runPassword) { throw "Must provide a runPassword" }
	if(-not $runUser) { throw "Must provide a runUser"}
 
	$command = "schtasks /CREATE /TN '$taskname' /TR '$taskRun' /SC '$schedule' /RU '$runUser' /RP '$runPassword' "
 
	($user,"U"),
	($password,"P"),
	($modifer,"MO"),
	($days,"D"),
	($months,"M"),
	($idleTime,"I"),
	($startTime,"ST"),
	($server,"S"),
	($startDate,"SD"),
	($endDate,"ED")| 
		%{
			if($_[0]) { $command += " /$($_[1]) '$($_[0])' " }
		}
 
	if($verbose -or $whatif) { $command }
	if(-not $whatif) { Invoke-Expression $command }
}
