New-ScheduledTaskTrigger

New-ScheduledTaskTrigger [-Once*] [-RandomDelay <TimeSpan>] [-RepetitionDuration <TimeSpan>] [-RepetitionInterval<TimeSpan>] -At* <DateTime> [<CommonParameters>]
New-ScheduledTaskTrigger [-Weekly*] [-RandomDelay <TimeSpan>] [-WeeksInterval <Int32>] -At* <DateTime> -DaysOfWeek*<DayOfWeek[]> [<CommonParameters>]
New-ScheduledTaskTrigger [-Daily*] [-DaysInterval <Int32>] [-RandomDelay <TimeSpan>] -At* <DateTime>[<CommonParameters>]
New-ScheduledTaskTrigger [-At*LogOn] [-RandomDelay <TimeSpan>] [-User <String>] [<CommonParameters>]
New-ScheduledTaskTrigger [-At*Startup] [-RandomDelay <TimeSpan>] [<CommonParameters>]

The New-ScheduledTaskTrigger cmdlet creates and returns a new scheduled task trigger object.

You can use a time-based trigger or an event-based trigger to start a task. Time-based triggers include starting a task at a specific time or starting a task multiple times on a daily or weekly schedule. Event-based triggers include starting a task when the system starts up or when a user logs on to the computer. Each task can contain one or more triggers, which means there are many ways that you can start a task. If a task has multiple triggers, Task Scheduler starts the task when any of the triggers occur.

Parameters

-At <DateTime>

  • This value is required

Specifies a date and time to trigger the task. This paramater is valid for calendar-based triggers (Once, Daily, Weekly).

-AtLogOn <SwitchParameter>

  • This value is required

Indicates that a trigger starts a task when a user logs on.

-AtStartup <SwitchParameter>

  • This value is required

Indicates that a trigger starts a task when the system is started.

-Daily <SwitchParameter>

  • This value is required

Indicates that a trigger starts a task on a recurring daily schedule.

-DaysInterval [<Int32>]

Specifies the interval between the days in the schedule. An interval of 1 produces a daily schedule. An interval of 2 produces an every-other day schedule.

-DaysOfWeek <DayOfWeek[]>

  • This value is required

Specifies an array of the days of the week on which Task Scheduler runs the task.

-Once <SwitchParameter>

  • This value is required

Indicates that a trigger starts a task once at a time specified in the At parameter.

-RandomDelay [<TimeSpan>]

Specifies a random amount of time to delay the start time of the trigger. The delay time is a random time between the time the task triggers and the time that you specify in this setting.

-RepetitionDuration [<TimeSpan>]

Specifies how long the repetition pattern repeats after the task starts.

-RepetitionInterval [<TimeSpan>]

Specifies an amount of time between each restart of the task. The task will run, wait for the time interval specified, and then run again. This cycle continues for the time that you specify for the RepetitionDuration parameter.

-User [<String>]

Specifies the identifier of the user for a trigger that starts a task when a user logs on.

-Weekly <SwitchParameter>

  • This value is required

Indicates that the trigger starts a task on a recurring weekly schedule.

-WeeksInterval [<Int32>]

Specifies the interval between the weeks in the schedule. An interval of 1 produces a weekly schedule. An interval of 2 produces an every-other week schedule.

<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,ErrorAction, ErrorVariable, WarningAction, WarningVariable,OutBuffer, PipelineVariable, and OutVariable.

Examples
  1. Register a scheduled task that starts a task once:
    1. The second command creates a scheduled task trigger that starts the task once at 3:00 A.M and assigns the ScheduledTaskTrigger object to the $Stt variable.:
      PS C:\> $Sta = New-ScheduledTaskAction -Execute "Cmd"
      
      PS C:\> $Stt = New-ScheduledTaskTrigger -Once -At 3am
      

      The second command creates a scheduled task trigger that starts the task once at 3:00 A.M and assigns the ScheduledTaskTrigger object to the $Stt variable.

    2. The third command registers the scheduled task Task01 to run the task action named Cmd once at 3:00 A.M:
      PS C:\> Register-ScheduledTask Task01 -Action $Sta -Trigger $Stt
      

      This example registers a scheduled task that starts once.

      The first command creates a scheduled task action named Cmd and assigns the ScheduledTaskAction object to the $Sta variable.

  2. Register a scheduled task that starts every day:
    1. The second command creates a scheduled task trigger that starts every day at 3:00 A.M and assigns the ScheduledTaskTrigger object to the $Stt variable.:
      PS C:\> $Sta = New-ScheduledTaskAction -Execute "Cmd"
      
      PS C:\> $Stt = New-ScheduledTaskTrigger -Daily -At 3am
      

      The second command creates a scheduled task trigger that starts every day at 3:00 A.M and assigns the ScheduledTaskTrigger object to the $Stt variable.

    2. The third command registers the scheduled task Task01 to run the task action named Cmd every day at 3:00 A.M:
      PS C:\> Register-ScheduledTask Task01 -Action $Sta -Settings $Stt
      

      This example registers a scheduled task that starts every day.

      The first command creates a scheduled task action named Cmd and assigns the ScheduledTaskAction object to the $Sta variable.

  3. Register a scheduled task that starts every 3 days:
    1. The second command creates a scheduled task trigger that starts every 3 days at 3:00 A.M and assigns the ScheduledTaskTrigger object to the $Stt variable.:
      PS C:\> $Sta = New-ScheduledTaskAction -Execute "Cmd"
      
      PS C:\> $Stt = New-ScheduledTaskTrigger -Daily -DaysInterval 3 -At 3am
      

      The second command creates a scheduled task trigger that starts every 3 days at 3:00 A.M and assigns the ScheduledTaskTrigger object to the $Stt variable.

    2. The third command registers the scheduled task Task01 to run the task action named cmd every 3 days at 3:00 A.M:
      PS C:\> Register-ScheduledTask Task01 -Action $Sta -Settings $Stt
      

      This example registers a scheduled task that starts every 3 days.

      The first command creates a scheduled task action named Cmd and assigns the ScheduledTaskAction object to the $Sta variable.

  4. Register a scheduled task that starts every-other week:
    1. The second command creates a scheduled task trigger that starts every other Sunday at 3:00 A.M and assigns the ScheduledTaskTrigger object to the $Stt variable.:
      PS C:\> $Sta = New-ScheduledTaskAction -Execute "Cmd"
      
      PS C:\> $Stt = New-ScheduledTaskTrigger -Weekly -WeeksInterval 2 -DaysOfWeek Sunday -At 3am
      

      The second command creates a scheduled task trigger that starts every other Sunday at 3:00 A.M and assigns the ScheduledTaskTrigger object to the $Stt variable.

    2. The third command registers the scheduled task Task01 to run the task action named Cmd every other Sunday at 3:00 A.M:
      PS C:\> Register-ScheduledTask Task01 -Action $Sta -Settings $Stt
      

      This example registers a scheduled task that starts every other week.

      The first command creates a scheduled task action named Cmd and assigns the ScheduledTaskAction object to the $Sta variable.

  5. Register a scheduled task that starts when a user logs on:

      PS C:\> $Sta = New-ScheduledTaskAction -Execute "Cmd"
      
      PS C:\> $Stt = New-ScheduledTaskTrigger -AtLogon
      

      The second command creates a scheduled task trigger that starts when a user logs on, and assigns the ScheduledTaskTrigger object to the $Stt variable.
