On a specific resource: There is only one instance of the task, and it is bound to a resource.You only want it run once, and you don’t care which node runs the task. A good example is a task that runs a report on the cluster. After it is triggered, the other nodes recognize it as having been triggered, and they do not attempt to run it on the other nodes. On any node: There is only one instance of the task, and the task triggers on only one node.Tasks on a cluster server can be specified to run as follows: One other important feature about scheduled tasks that is not shared by scheduled jobs is the ability to deal with the specifics of tasks on a failover cluster server. Register-ScheduledTask –TaskName “Notepad As Admin at 5AM” -Action $ST_A –Trigger $ST_T –User “Contoso\Administrator” Managing failover clusters with scheduled tasks $ST_T = New-ScheduledTaskTrigger -Once -At 5am $ST_A = New-ScheduledTaskAction –Execute “c:\windows\system32\notepad.exe” For example, the commands below create a scheduled task that launches Notepad as an Administrator at 5:00 AM. The cmdlets let you define, view, and modify scheduled task objects and all the component objects that make up a scheduled task. You can see more details and examples if you use the -Detailed, -Examples, or -Full parameters. To see the syntax and description for any cmdlet, run Get-Help CmdletName. Hint You can also abbreviate that to gcm –m ScheduledTasks. To see the complete list of cmdlets on your system, run the command:
#Windows 10 scheduled tasks windows#
You can find the cmdlets that work with scheduled tasks in the ScheduledTasks module that is included with Windows 8 and Windows Server 2012.
Additional settings that further configure the task and control how the action is run.A principal that identifies the context to use to execute an action.A trigger that defines the time or system event that determines when the program is to be run.An action that specifies the program to be run.However, that’s a relatively minor limitation because there is nothing to prevent your scheduled task from saving its output to disk in some form that you can later retrieve and manipulate. According to Windows PowerShell MVP, Karl Prosser, the output of scheduled tasks goes to “the same place where your clothes dryer puts your lost socks.”īecause a scheduled job is always Windows PowerShell script, even if that script is used to run a non-Windows PowerShell program, it is possible for the system to capture that predictable output: the Windows PowerShell object that is returned at the end of the script block. Because a scheduled task can run almost anything that is runnable on a Windows computer, it’s not possible to anticipate and capture the output of a scheduled task. The only thing that is really missing from a scheduled task is the native ability to capture and manipulate the output of the task. Each cmdlet consumes, processes, or returns an object, unlike the older command-line tools that generally consume and emit only text strings. Although SchTasks.exe enables you to fully interact with your tasks from a command line, it is not object-oriented, as are the ScheduledTask module’s cmdlets. Scheduled tasks are a core infrastructure component of Windows and, they are used extensively by many Windows components and other products that run on Windows. They enable you to schedule the running of almost any program or process, in any security context, triggered by a timer or a wide variety of system events. The Task Scheduler graphical UI program (TaskSchd.msc), and its command-line equivalent (SchTasks.exe) have been part of Windows since some of the earliest days of the operating system. Scheduled tasks are much more general than scheduled jobs. Be sure to read the official help topics for both modules: PSScheduledJob Module and Scheduled Task Cmdlets in Windows PowerShell. The best one to use depends on what you’re trying to schedule.ĭave will start us out with a review of scheduled tasks, and I’ll jump in with some info about scheduled jobs. They’re actually different approaches to solving the same problem, and they share some common technology.
In the mix were two modules that sound like they do almost the same thing: PSScheduledJob and ScheduledTasks. Much of this was the work of Microsoft teams building Windows PowerShell interfaces for Windows tools. Windows PowerShell 3.0 introduced dozens of new modules and thousands of new cmdlets. Today Dave Bishop, senior technical writer on the Windows Server team, and June Blender, senior programming writer on the Windows Azure Active Directory team, investigate scheduled tasks and scheduled jobs in Windows PowerShell. Microsoft Scripting Guy, Ed Wilson, is here. Summary: Learn about using scheduled tasks and scheduled jobs in Windows PowerShell.
