Stop-Job

Applies To: Windows PowerShell 2.0

Stops a Windows PowerShell background job.

Syntax

Stop-Job [[-InstanceId] <Guid[]>] [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Stop-Job [-Job] <Job[]> [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Stop-Job [[-Name] <string[]>] [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Stop-Job [-Id] <Int32[]> [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Stop-Job [-State {<NotStarted> | <Running> | <Completed> | <Failed> | <Stopped> | <Blocked>}] [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Description

The Stop-Job cmdlet stops Windows 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 jobs that were started by using Start-Job or the AsJob parameter of Invoke-Command. When you stop a background job, Windows 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 Remove-Job.

Parameters

-Id <Int32[]>

Stops jobs with the specified IDs. The default is all jobs in the current session.

The ID is an integer that uniquely identifies the job within the current session. It is easier to remember and type than the InstanceId, but it is unique only within the current session. You can type one or more IDs (separated by commas). To find the ID of a job, type "Get-Job" without parameters.

-InstanceId <Guid[]>

Stops only jobs with the specified instance IDs. 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.

-Job <Job[]>

Specifies the jobs to be stopped. 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.

-Name <string[]>

Stops only the jobs with the specified friendly names. 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.

-PassThru

Returns an object representing the new background job. By default, this cmdlet does not generate any output.

-State <JobState>

Stops only jobs within the specified state. Valid values are NotStarted, Running, Completed, Stopped, Failed, and Blocked.

-Confirm

Prompts you for confirmation before executing the command.

-WhatIf

Describes what would happen if you executed the command without actually executing the command.

<CommonParameters>

This command supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, OutBuffer, OutVariable, WarningAction, and WarningVariable. For more information, see about_CommonParameters.

Inputs and Outputs

The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet returns.

Example 1

C:\PS>$s = new-pssession -computername Server01 -credential domain01\admin02

C:\PS> $j = invoke-command -session $s -scriptblock {start-job -scriptblock {get-eventlog system}} 

C:\PS> invoke-command -session $s -scriptblock {param($j) stop-job -job $j} -ArgumentList $j

Description

-----------

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 Invoke-Command to run a Start-Job command remotely, the job object is stored on the remote computer, and 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 Windows PowerShell session (PSSession) on the Server01 computer and saves 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 "param" keyword to declare the local variables in the command, and it uses the ArgumentList parameter to supply values for the variables.

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

Example 2

C:\PS>stop-job -state failed

Description

-----------

This command stops all jobs with a State value of "Failed".

Example 3

C:\PS>stop-job -name job1

Description

-----------

This command stops the Job1 background job.

Example 4

C:\PS>stop-job -id 1, 3, 4

Description

-----------

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

Example 5

C:\PS>get-job | stop-job

Description

-----------

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

Example 6

C:\PS>stop-job -state blocked

Description

-----------

This command stops all the jobs with a job status of "Blocked".

Example 7

C:\PS>get-job | format-table ID, Name, Command, @{Label="State";Expression={$_.jobstateinfo.state}}, I
nstanceID -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

C:\PS> stop-job -instanceid e3bbfed1-9c53-401a-a2c3-a8db34336adf

Description

-----------

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

The first command uses a Get-Job command 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 with the InstanceID parameter to stop a selected job.

Example 8

C:\PS>$j = invoke-command -computername Server01 -scriptblock {get-eventlog system} -asjob

C:\PS> $j | stop-job -passthru

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

Description

-----------

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 Invoke-Command, the job object is located on the local computer, even though the job runs on the remote computer. As such, 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 Start-Job 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".
