SYNTAX

JobParameterSet (Default)

Debug-Job [-Job] <Job> [-WhatIf] [-Confirm] [<CommonParameters>]

JobNameParameterSet

Debug-Job [-Name] <String> [-WhatIf] [-Confirm] [<CommonParameters>]

JobIdParameterSet

Debug-Job [-Id] <Int32> [-WhatIf] [-Confirm] [<CommonParameters>]

JobInstanceIdParameterSet

Debug-Job [-InstanceId] <Guid> [-WhatIf] [-Confirm] [<CommonParameters>]

DESCRIPTION

The Debug-Job cmdlet lets you debug scripts that are running within jobs. The cmdlet is designed to debug Windows PowerShell Workflow jobs, background jobs, and jobs running in remote sessions. Debug-Job accepts a running job object, name, ID, or instance ID as input, and starts a debugging session on the script it is running. The debugger quit command stops the job and running script. Starting in Windows PowerShell 5.0, the exit command detaches the debugger, and allows the job to continue to run.

EXAMPLES

Example 1: Debug a job by job ID

PS C:\> Debug-Job -ID 3
Id     Name            PSJobTypeName   State         HasMoreData     Location             Command
--     ----            -------------   -----         -----------     --------             -------
3      Job3            RemoteJob       Running       True            PowerShellIx         TestWFDemo1.ps1
          Entering debug mode. Use h or ? for help.

          Hit Line breakpoint on 'C:\TestWFDemo1.ps1:8'

          At C:\TestWFDemo1.ps1:8 char:5
          +     Write-Output -InputObject "Now writing output:" 
          +     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
          [DBG:PowerShellIx]: PS C:\> > list

              3: 
              4:  workflow SampleWorkflowTest
              5:  {
              6:      param ($MyOutput) 
              7: 
              8:*     Write-Output -InputObject "Now writing output:" 
              9:      Write-Output -Input $MyOutput
             10: 
             11:      Write-Output -InputObject "Get PowerShell process:" 
             12:      Get-Process -Name powershell
             13: 
             14:      Write-Output -InputObject "Workflow function complete." 
             15:  }
             16: 
             17:  # Call workflow function
             18:  SampleWorkflowTest -MyOutput "Hello"

This command breaks into a running job with an ID of 3.

PARAMETERS

-Confirm

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: cf

Required: False

Parameter Sets: JobIdParameterSet
Aliases: 

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

-InstanceId

Specifies the instance ID GUID of a running job. To get the InstanceId of a job, run the Get-Job cmdlet, piping the results into a Format-* cmdlet, as shown in the following example:

Get-Job | Format-List -Property Id,Name,InstanceId,State

Type: Guid
Parameter Sets: JobInstanceIdParameterSet
Aliases: 

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

-Job

Specifies a running job object. The simplest way to use this parameter is to save the results of a Get-Job command that returns the running job that you want to debug in a variable, and then specify the variable as the value of this parameter.

Aliases: 

Required: True
Position: 0
Default value: None
Accept pipeline input: True (ByPropertyName, ByValue)

Type: String
Parameter Sets: JobNameParameterSet
Aliases: 

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

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.
