I have this batch file which runs the powershell script.
I want to run it the background but if I run with "windowstyle hidden" still visible.
powershell -ExecutionPolicy ByPass -windowstyle hidden -File "C:\\script.ps1"
You can run, eg long running scripts, as a jobs.
To start it you run
$job = Start-Job -ScriptBlock {Get-Process}
this will start the Get-Process
cmdlet in the background. The script can be also some custom made script or a longer script, it doesn't need to be a one-liner.
You can check its status by running
$job | Get-Job
and to receive the output you run
$job | Receive-Job
just note that once the data is received, it's lost. You can only receive it once, after that it's up to you to save it in a variable or later processing.
Finally to remove the job from the queue you run
$job | Remove-Job
I use the following function:
function bg() {
Start-Process `
-WorkingDirectory (Get-Location) `
-NoNewWindow `
-FilePath "powershell" `
-ArgumentList "-NoProfile -command `"$args`" "
}
It starts a new powershell instance which is executed in background and allows the usage of cmdlets. You call it like:
bg "Start-Sleep 2; get-location; write 'done' "
