Powershell - Check on Remote Process, if done continue

Question

As part of a backup operation, I am running the 7zip command to compress a folder into a single .7z file. No problems there as I am using the InVoke-WMIMethod.<

Answer 1

You should be able to do it with a do... while loop that just sleeps until the process is finished.

 do { 
    "waiting"
    start-sleep 10 
    } while (gwmi -class win32_process -ComputerName $remotehost | Where ProcessName -eq "7za.exe")

Answer 2

You can invoke the Wait-Process cmdlet on the remote computer with the Invoke-Command cmdlet. Example:

$process = Invoke-WmiMethod -Class Win32_Process -Name create -ArgumentList notepad -ComputerName RemoteComputer

Invoke-Command -ComputerName RemoteComputer -ScriptBlock { param($processId) Wait-Process -ProcessId $processId } -ArgumentList $process.ProcessId

Since you mentioned using Invoke-Command is not an option, another option is polling. Example:

$process = Invoke-WmiMethod -Class Win32_Process -Name create -ArgumentList notepad -ComputerName hgodasvccr01
$processId = $process.ProcessId

$runningCheck = { Get-WmiObject -Class Win32_Process -Filter "ProcessId='$processId'" -ComputerName hgodasvccr01 -ErrorAction SilentlyContinue | ? { ($_.ProcessName -eq 'notepad.exe') } }

while ($null -ne (& $runningCheck))
{
 Start-Sleep -m 250
}

Write-Host "Process: $processId is not longer running"
