In PowerShell 5.1 I have created a background job with the below command
Start-Job { while($true) { Get-Random; Start-Sleep 5 } } -Name Sleeper
The job gets created fine and it returns the results with Receive-Job as well. And I stopped it with Stop-Job cmdlet.
And I would like to restart it again in the same PS session.
I execute Get-Job cmdlet and I see the job there in the Stopped state.
How to restart it without recreating it?
I could not get this information in about_Jobs.
The script block is just a sample script. I am more interested to know if there is a way to restart the already existing job.
You cannot re-run completed jobs. One thing you could do is start a new job from the command of the completed one:
$j1 = Start-Job -ScriptBlock { ... }
...
$j2 = Start-Job -ScriptBlock ([scriptblock]::Create($j1.Command))
If you need something that you can re-run at will you probably want a scheduled task or a scheduled job:
$trigger = New-JobTrigger -Daily -At '2:00 PM'
$options = New-ScheduledJobOption -StartIfOnBattery -StartIfIdle
Register-ScheduledJob -Name 'myjob' -ScriptBlock { ... } -Trigger $trigger -ScheduledJobOption $options
and (re-)invoke it e.g. like this:
(Get-ScheduledJob -Name 'myjob').StartJob()
