C:\PS>$job = start-job -scriptblock {get-process}

C:\PS> receive-job -job $job

These commands use the Job parameter to get the results of a particular job. The first command uses the Start-Job cmdlet to start a job that runs a "Get-Process" command. The command uses the assignment operator (=) to save the resulting job object in the $job variable.

The second command uses the Receive-Job cmdlet to get the results of the job. It uses the Job parameter to specify the job.

C:\PS>$job = start-job -scriptblock {get-process}

C:\PS> $job | receive-job

This example is the same as Example 2, except that the command uses a pipeline operator (|) to send the job object to Receive-Job. As a result, the command does not need a Job parameter to specify the job.

C:\PS>$j = invoke-command -computername Server01, Server02, Server03 -scriptblock {get-service} -AsJob

C:\PS> $j.childjobs

Description
-----------
These commands use the Name parameter of Receive-Job to get the results of one of several background jobs run on remote computers. 

The first command uses the Invoke-Command cmdlet to start a background job that runs a Get-Service command on three remote computers. The command uses the AsJob parameter to run the command as a background job. The command saves the resulting job object in the $j variable.

When you use the AsJob parameter of Invoke-Command to start a job, the job object is created on the local computer, even though the job runs on the remote computers. As a result, you use local commands to manage the job.

Also, when you use AsJob, Windows PowerShell returns one job object that contains a child job for each job that was started. In this case, the job object contains three child jobs, one for each job on each remote computer.

The second command uses the dot method to display the value of the ChildJobs property of the job object in $j. The display shows that the command created three child jobs, one for the job on each remote computer.
 
The third command uses the Receive-Job cmdlet to get the results of the Job3 child job that ran on the Server02 computer. It uses the Name parameter to specify the name of the child job and the Keep parameter to save the job results even after they are received.

C:\PS>$s = new-pssession -computername Server01, Server02, Server03

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

C:\PS> $j

Id   Name     State      HasMoreData   Location   Command
--   ----     -----      -----------   --------   -------
1    Job1     Completed  True          Localhost  get-eventlog system
2    Job2     Completed  True          Localhost  get-eventlog system
3    Job3     Completed  True          Localhost  get-eventlog system

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


Description
-----------
This example shows how to get the results of background jobs run on three remote computers.

The first command uses the New-PSSession cmdlet to create three PSSessions, one on each of the servers specified in the command. It saves the PSSessions in the $s variable.

The second command uses the Invoke-Command cmdlet to run a Start-Job command in each of the PSSessions in the $s variable. The job runs a Get-Eventlog command that gets the events in the System log. The command saves the results in the $j variable.

Because the command used Invoke-Command to run the Start-Job command, the command actually started three independent jobs on each of the three computers. As a result, the command returned three job objects representing three jobs run locally on three different computers.

The third command displays the three job objects in $j.  

The fourth command uses Invoke-Command to run a Receive-Job command in each of the PSSessions in $s and save the results in the $results variable.

Because $j is a local variable, the script block uses the "param" keyword to declare the variables in the command and the ArgumentList parameter to supply the value of $j.
