Windows PowerShell command on Get-command Get-JobTrigger

NAME

Get-JobTrigger

SYNOPSIS

Gets the job triggers of scheduled jobs.

SYNTAX

Get-JobTrigger [-Id] [[-TriggerId] ] []

Get-JobTrigger [-InputObject] [[-TriggerId] ] []

Get-JobTrigger [-Name] [[-TriggerId] ] []

DESCRIPTION

The Get-JobTrigger cmdlet gets the job triggers of scheduled jobs. You can use this command to examine the job

triggers or to pipe the job triggers to other cmdlets. A job trigger defines a recurring schedule or conditions for starting a scheduled job. Job triggers are not saved to disk independently; they are part of a scheduled job. To get a job trigger, specify the scheduled job that the trigger starts.

Use the parameters of the Get-JobTrigger cmdlet to identify the scheduled jobs. You can identify the scheduled

jobs by their names or identification numbers, or by entering or piping ScheduledJob objects, such as those that

are returned by the Get-ScheduledJob cmdlet, to Get-JobTrigger . Get-JobTrigger is one of a collection of job

scheduling cmdlets in the PSScheduledJob module that is included in Windows PowerShell. For more information about Scheduled Jobs, see the About topics in the PSScheduledJob module. Import the

PSScheduledJob module and then type: `Get-Help about_Scheduled*` or see about_Scheduled_Jobs.

This cmdlet was introduced in Windows PowerShell 3.0.

PARAMETERS

-Id

Specifies the identification number of a scheduled job. Get-JobTrigger gets the job trigger of the specified

Get-ScheduledJob cmdlet.

Required? true Position? 0 Default value None Accept pipeline input? False Accept wildcard characters? false

Get-JobTrigger .

-Name

Specifies the name of a scheduled job. Get-JobTrigger gets the job trigger of the specified scheduled job.

Wildcards are supported.

To get the names of scheduled jobs on the local computer or a remote computer, use the Get-ScheduledJob cmdlet.

Required? true Position? 0 Default value None Accept pipeline input? False Accept wildcard characters? false

-TriggerId

Gets the specified job triggers. Enter the trigger IDs of one or more job triggers of a scheduled job. Use

this parameter when the scheduled job that is specified by the Name , ID , or InputObject parameters has

multiple job triggers. Required? false Position? 1 Default value None Accept pipeline input? False Accept wildcard characters? false This cmdlet supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer, PipelineVariable, and OutVariable. For more information, see about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).

INPUTS

Microsoft.PowerShell.ScheduledJob.ScheduledJobDefinition

You can pipe a scheduled job from Get-ScheduledJob to Get-JobTrigger .

OUTPUTS

Microsoft.PowerShell.ScheduledJob.ScheduledJobTrigger

NOTES

Example 1: Get a job trigger by scheduled job name

PS C:\>Get-JobTrigger -Name "BackupJob"

The command uses the Name parameter of Get-JobTrigger to get the job triggers of the BackupJob scheduled job.

Example 2: Get a job trigger by ID

The first command uses the Get-ScheduledJob cmdlet to display the scheduled jobs on the local computer. The

display includes the IDs of the scheduled jobs.

PS C:\>Get-ScheduledJob

Id Name Triggers Command Enabled

-- ---- -------- ------- -------

1 ArchiveProjects {1} \\Server\Share\Archive-Projects.ps1 True

2 Backup {1,2} \\Server\Share\Run-Backup.ps1 True

3 Test-HelpFiles {1} \\Server\Share\Test-HelpFiles.ps1 True

4 TestJob {} \\Server\Share\Run-AllTests.ps1 True

The second command uses the **Get-JobTrigger** cmdlet to get the job trigger for the Test-HelpFiles job (ID = 3)

PS C:\>Get-JobTrigger -ID 3

The example uses the ID parameter of Get-JobTrigger to get the job triggers of a scheduled job.

Example 3: Get job triggers by piping a job

PS C:\>Get-ScheduledJob -Name *Backup*, *Archive* | Get-JobTrigger

This command gets the job triggers of all jobs that have Backup or Archive in their names.

Example 4: Get the job trigger of a job on a remote computer

PS C:\>Invoke-Command -ComputerName Server01 { Get-ScheduledJob Backup | Get-JobTrigger -TriggerID 2 }

This command gets one of the two job triggers of a scheduled job on a remote computer.

The command uses the Invoke-Command cmdlet to run a command on the Server01 computer. It uses the Get-ScheduledJob

cmdlet to get the Backup scheduled job, which it pipes to the Get-JobTrigger cmdlet. It uses the TriggerID

parameter to get only the second trigger.

Example 5: Get all job triggers

PS C:\>Get-ScheduledJob | Get-JobTrigger | Format-Table -Property ID, Frequency, At, DaysOfWeek, Enabled,

@{Label="ScheduledJob";Expression={$_.JobDefinition.Name}} -AutoSize

Id Frequency At DaysOfWeek Enabled ScheduledJob

-- --------- -- ---------- ------- ------------

1 Weekly 9/28/2011 3:00:00 AM {Monday} True Backup

1 Daily 9/27/2011 11:00:00 PM True Test-HelpFiles

This command gets all job triggers of all scheduled jobs on the local computer.

The command uses the Get-ScheduledJob to get the scheduled jobs on the local computer and pipes them to

Get-JobTrigger , which gets the job trigger of each scheduled job (if any).

To add the name of the scheduled job to the job trigger display, the command uses the calculated property feature

of the Format-Table cmdlet. In addition to the job trigger properties that are displayed by default, the command

creates a new ScheduledJob property that displays the name of the scheduled job.

Example 6: Get the job trigger property of a scheduled job

The command uses the Get-ScheduledJob cmdlet to get the Test-HelpFiles scheduled job. Then it uses the dot method

(.) to get the JobTriggers property of the Test-HelpFiles scheduled job.

PS C:\>(Get-ScheduledJob Test-HelpFiles).JobTriggers

The second command uses the Get-ScheduledJob cmdlet to get all scheduled jobs on the local computer. It uses the

ForEach-Object cmdlet to get the value of the JobTrigger property of each scheduled job.

PS C:\>Get-ScheduledJob | foreach {$_.JobTriggers}

The job triggers of a scheduled job are stored in the JobTriggers property of the job. This example shows

alternatives to using the Get-JobTrigger cmdlet to get job triggers. The results are identical to using the

Get-JobTrigger cmdlet and the techniques can be used interchangeably.

Example 7: Compare job triggers

The first command gets the job trigger of the ArchiveProjects scheduled job. The command pipes the job trigger to

the Tee-Object cmdlet, which saves the job trigger in the $T1 variable and displays it at the command line.

PS C:\>Get-ScheduledJob -Name ArchiveProjects | Get-JobTrigger | Tee-Object -Variable T1

Id Frequency Time DaysOfWeek Enabled

-- --------- ---- ---------- -------

0 Daily 9/26/2011 3:00:00 AM True

The second command gets the job trigger of the Test-HelpFiles scheduled job. The command pipes the job trigger to

the Tee-Object cmdlet, which saves the job trigger in the $T2 variable and displays it at the command line.

PS C:\>Get-ScheduledJob -Name "Test-HelpFiles" | Get-JobTrigger | Tee-Object -Variable T2

Id Frequency Time DaysOfWeek Enabled

-- --------- ---- ---------- -------

0 Daily 9/26/2011 3:00:00 AM True

The third command compares the job triggers in the $t1 and $t2 variables. It uses the Get-Member cmdlet to get the

properties of the job trigger in the $t1 variable. It pipes the properties to the ForEach-Object cmdlet, which

compares each property to the properties of the job trigger in the $t2 variable by name. The command then pipes

the differing properties to the Format-List cmdlet, which displays them in a list.The output indicates that,

although the job triggers appear to be the same, the HelpFiles job trigger includes a random delay of three (3) minutes.

PS C:\>$T1 | Get-Member -Type Property | ForEach-Object { Compare-Object $T1 $T2 -Property $_.Name}

00:00:00 => 00:03:00 <= This example shows how to compare the job triggers of two scheduled jobs.
