Description

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.

Examples

Example 1: Register a scheduled task that starts a task once

PS C:\>$Sta = New-ScheduledTaskAction -Execute "Cmd"
PS C:\>$Stt = New-ScheduledTaskTrigger -Once -At 3am
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. 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. The third command registers the scheduled task Task01 to run the task action named Cmd once at 3:00 A.M.

Example 2: Register a scheduled task that starts every day

PS C:\>$Sta = New-ScheduledTaskAction -Execute "Cmd"
PS C:\>$Stt = New-ScheduledTaskTrigger -Daily -At 3am
PS C:\>Register-ScheduledTask Task01 -Action $Sta -Trigger $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. 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. The third command registers the scheduled task Task01 to run the task action named Cmd every day at 3:00 A.M.

Example 3: Register a scheduled task that starts every 3 days

PS C:\>$Sta = New-ScheduledTaskAction -Execute "Cmd"
PS C:\>$Stt = New-ScheduledTaskTrigger -Daily -DaysInterval 3 -At 3am
PS C:\>Register-ScheduledTask Task01 -Action $Sta -Trigger $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. 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. The third command registers the scheduled task Task01 to run the task action named cmd every 3 days at 3:00 A.M.

Example 4: Register a scheduled task that starts every-other week

PS C:\>$Sta = New-ScheduledTaskAction -Execute "Cmd"
PS C:\>$Stt = New-ScheduledTaskTrigger -Weekly -WeeksInterval 2 -DaysOfWeek Sunday -At 3am
PS C:\>Register-ScheduledTask Task01 -Action $Sta -Trigger $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. 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. The third command registers the scheduled task Task01 to run the task action named Cmd every other Sunday at 3:00 A.M.

Example 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
PS C:\>Register-ScheduledTask Task01 -Action $Sta -Trigger $Stt

This example registers a scheduled task that starts when a user logs on.

The first command creates a scheduled task action named Cmd and assigns the ScheduledTaskAction object to the $Sta variable. The second command creates a scheduled task trigger that starts when a user logs on, and assigns the ScheduledTaskTrigger object to the $Stt variable. The third command registers the scheduled task Task01 to run the task action named Cmd when a user logs on.
