Description

The Stop-Job cmdlet stops PowerShell background jobs that are in progress. You can use this cmdlet to stop all jobs or stop selected jobs based on their name, ID, instance ID, or state, or by passing a job object to Stop-Job.

You can use Stop-Job to stop background jobs, such as those that were started by using the Start-Job cmdlet or the AsJob parameter of any cmdlet. When you stop a background job, PowerShell completes all tasks that are pending in that job queue and then ends the job. No new tasks are added to the queue after this command is submitted.

This cmdlet does not delete background jobs. To delete a job, use the Remove-Job cmdlet.

Starting in Windows PowerShell 3.0, Stop-Job also stops custom job types, such as workflow jobs and instances of scheduled jobs. To enable Stop-Job to stop a job with custom job type, import the module that supports the custom job type into the session before you run a Stop-Job command, either by using the Import-Module cmdlet or by using or getting a cmdlet in the module. For information about a particular custom job type, see the documentation of the custom job type feature.

Examples

Example 1: Stop a job on a remote computer by using Invoke-Command

$s = New-PSSession -ComputerName Server01 -Credential Domain01\Admin02
$j = Invoke-Command -Session $s -ScriptBlock {Start-Job -ScriptBlock {Get-EventLog System}}
Invoke-Command -Session $s -ScriptBlock { Stop-job -Job $Using:j }

This example shows how to use the Stop-Job cmdlet to stop a job that is running on a remote computer.

Because the job was started by using the Invoke-Command cmdlet to run a Start-Job command remotely, the job object is stored on the remote computer. You must use another Invoke-Command command to run a Stop-Job command remotely. For more information about remote background jobs, see about_Remote_Jobs.

The first command creates a PowerShell session (PSSession) on the Server01 computer, and then stores the session object in the $s variable. The command uses the credentials of a domain administrator.

The second command uses the Invoke-Command cmdlet to run a Start-Job command in the session. The command in the job gets all of the events in the System event log. The resulting job object is stored in the $j variable.

The third command stops the job. It uses the Invoke-Command cmdlet to run a Stop-Job command in the PSSession on Server01. Because the job objects are stored in $j, which is a variable on the local computer, the command uses the Using scope modifier to identify $j as a local variable. For more information about the Using scope modifier, see about_Remote_Variables.

When the command finishes, the job is stopped and the PSSession in $s is available for use.

Example 2: Stop a background job

Stop-Job -Name "Job1"

This command stops the Job1 background job.

Example 3: Stop several background jobs

Stop-Job -Id 1, 3, 4

This command stops three jobs. It identifies them by their IDs.

Example 4: Stop all background jobs

Get-Job | Stop-Job

This command stops all of the background jobs in the current session.

Example 5: Stop all blocked background jobs

Stop-Job -State Blocked

This command stops all the jobs that are blocked.

Example 6: Stop a job by using an instance ID

Get-Job | Format-Table ID, Name, Command, @{Label="State";Expression={$_.JobStateInfo.State}},
InstanceID -Auto

Id Name Command                 State  InstanceId
-- ---- -------                 -----  ----------
1 Job1 start-service schedule Running 05abb67a-2932-4bd5-b331-c0254b8d9146
3 Job3 start-service schedule Running c03cbd45-19f3-4558-ba94-ebe41b68ad03
5 Job5 get-service s*         Blocked e3bbfed1-9c53-401a-a2c3-a8db34336adf

Stop-Job -InstanceId e3bbfed1-9c53-401a-a2c3-a8db34336adf

These commands show how to stop a job based on its instance ID.

The first command uses the Get-Job cmdlet to get the jobs in the current session. The command uses a pipeline operator (|) to send the jobs to a Format-Table command, which displays a table of the specified properties of each job. The table includes the Instance ID of each job. It uses a calculated property to display the job state.

The second command uses a Stop-Job command that has the InstanceID parameter to stop a selected job.

Example 7: Stop a job on a remote computer

$j = Invoke-Command -ComputerName Server01 -ScriptBlock {Get-EventLog System} -AsJob
$j | Stop-Job -PassThru

Id    Name    State      HasMoreData     Location         Command
--    ----    ----       -----------     --------         -------
5     Job5    Stopped    True            user01-tablet    get-eventlog system

This example shows how to use the Stop-Job cmdlet to stop a job that is running on a remote computer.

Because the job was started by using the AsJob parameter of the Invoke-Command cmdlet, the job object is located on the local computer, even though the job runs on the remote computer. Therefore, you can use a local Stop-Job command to stop the job.

The first command uses the Invoke-Command cmdlet to start a background job on the Server01 computer. The command uses the AsJob parameter to run the remote command as a background job.

This command returns a job object, which is the same job object that the Start-Job cmdlet returns. The command saves the job object in the $j variable.

The second command uses a pipeline operator to send the job in the $j variable to Stop-Job. The command uses the PassThru parameter to direct Stop-Job to return a job object. The job object display confirms that the state of the job is Stopped.

Parameters

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Filter

Specifies a hash table of conditions. This cmdlet stops jobs that satisfy all of the conditions. Enter a hash table where the keys are job properties and the values are job property values.

This parameter works only on custom job types, such as workflow jobs and scheduled jobs. It does not work on standard background jobs, such as those created by using the Start-Job cmdlet. For information about support for this parameter, see the help topic for the job type.

This parameter was introduced in Windows PowerShell 3.0.

Type:Hashtable
Position:0
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Id

Specifies the IDs of jobs that this cmdlet stops. The default is all jobs in the current session.

The ID is an integer that uniquely identifies the job in the current session. It is easier to remember and type than the instance ID, but it is unique only in the current session. You can type one or more IDs, separated by commas. To find the ID of a job, type Get-Job.

Type:Int32[]
Position:0
Default value:All jobs
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-InstanceId

Specifies the instance IDs of jobs that this cmdlet stops. The default is all jobs.

An instance ID is a GUID that uniquely identifies the job on the computer. To find the instance ID of a job, use Get-Job.

Type:Guid[]
Position:0
Default value:All jobs
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Job

Specifies the jobs that this cmdlet stops. Enter a variable that contains the jobs or a command that gets the jobs. You can also use a pipeline operator to submit jobs to the Stop-Job cmdlet. By default, Stop-Job deletes all jobs that were started in the current session.

Type:Job[]
Position:0
Default value:All jobs
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Name

Specifies friendly names of jobs that this cmdlet stops. Enter the job names in a comma-separated list or use wildcard characters (*) to enter a job name pattern. By default, Stop-Job stops all jobs created in the current session.

Because the friendly name is not guaranteed to be unique, use the WhatIf and Confirm parameters when stopping jobs by name.

Type:String[]
Position:0
Default value:All jobs
Required:True
Accept pipeline input:True
Accept wildcard characters:True
