Creates a scheduled task instance.

Syntax

Parameter Set: New0
New-ScheduledTask [[-Action] <CimInstance[]> ] [[-Trigger] <CimInstance[]> ] [[-Settings] <CimInstance> ] [[-Principal] <CimInstance> ] [[-Description] <String> ] [-AsJob] [-CimSession <CimSession[]> ] [-ThrottleLimit <Int32> ] [ <CommonParameters>]




Detailed Description

The New-ScheduledTask cmdlet creates an object that contains the definition of a scheduled task. New-ScheduledTask does not automatically register the object with the Task Scheduler service.

You can register a task to run any of the following application or file types: Win32 applications, Win16 applications, OS/2 applications, MS-DOS applications, batch files (*.bat), command files (*.cmd), or any properly registered file type.

Parameters

-Action<CimInstance[]>

Specifies an array of work items for a task to run. When you specify multiple actions, they run sequentially. A task can have up to 32 actions.

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

-Trigger<CimInstance[]>

Specifies an array of one or more trigger objects that cause a scheduled task to start.

A trigger is a set of criteria that starts a scheduled task when the criteria are met. You can use a time-based trigger or an event-based trigger to start a task, and one or more triggers can start a task. A task can have up to 48 triggers. For more information about triggers, see Triggers.

Examples

Example 1: Define a scheduled task and register it at a later time

In this example, the set of commands uses several cmdlets and variables to define and then register a scheduled task.

The first command uses the New-ScheduledTaskAction cmdlet to assign the variable $A to the executable file tskmgr.exe.

The second command uses the New-ScheduledTaskTrigger cmdlet to assign the variable $T to the value AtLogon.

The third command assigns the variable $P to the principal of the scheduled task, Contoso\Administrator.

The fourth command uses the New-ScheduledTaskSettingsSet cmdlet to assign the variable $S to a task settings object.

The fifth command creates a new task and assigns the variable $D to the task definition.

The sixth command (hypothetically) runs at a later time. It registers the new scheduled task and defines it by using the $D variable.


PS C:\> $A = New-ScheduledTaskAction –Execute "Taskmgr.exe"
PS C:\> $T = New-ScheduledTaskTrigger -AtLogon
PS C:\> $P = "Contoso\Administrator"
PS C:\> $S = New-ScheduledTaskSettingsSet
PS C:\> $D = New-ScheduledTask -Action $A -Principal $P -Trigger $T -Settings $S
PS C:\> Register-ScheduledTask T1 -InputObject $D
