PowerShell-仅在所有服务均已停止的情况下启动rocopy

Question

I'm new to PowerShell and was wondering if anyone can assist me with the following since I was unable to find any previous thread for this question on the site.

Question: Is there a way to write out a robocopy command so that it will only start if the services in $stopservices have all stopped? Below is what I have but at some points the service is still running when the robocopy starts and then errors out for "The process cannot access the file because it is being used by another process.".

<## Stop all services ##>
    write-host `r`n "Stopping services on "$server `r`n
    foreach ($service in $stopservices) 
    {
        set-service $service -ComputerName $server -StartupType Disabled -Status Stopped -PassThru
    }


<## Copy all files ##>
    $robocopy = "{0} {1} {2} /XF {3} {4} {5} /XD {6} {7} /MIR /MT /TEE /LOG:{8}" -f $robocopy, $source, $destination, $logPath
    Invoke-Expression $robocopy
    Pause

If the services aren't stopping you could try using the Stop-Service Cmdlet after Set-Service .

 Get-Service -Name $service -ComputerName $server | Stop-Service -Force 

Then you could wait for the services to stop by using the following while loop just before the Robocopy .

While($stopservices | Get-Service | ? {$_.Status -eq "Running" -or $_.Status -eq "Stopping"}){
    Sleep -Seconds 5
}

This will sleep the script for 5 seconds if 1 of the services in $stopservices are still running. Once all services do not have a Running or Stopping status the Robocopy will start. So the whole script might look something like this:

# Stop all services #
write-host `r`n "Stopping services on "$server `r`n
foreach ($service in $stopservices) 
{
    set-service $service -ComputerName $server -StartupType Disabled -Status Stopped -PassThru
    Get-Service -Name $service -ComputerName $server | Stop-Service -Force 

}

While($stopservices | Get-Service | ? {$_.Status -eq "Running" -or $_.Status -eq "Stopping"}){
    Sleep -Seconds 5
}

# Copy all files #
$robocopy = "{0} {1} {2} /XF {3} {4} {5} /XD {6} {7} /MIR /MT /TEE /LOG:{8}" -f $robocopy, $source, $destination, $logPath
Invoke-Expression $robocopy
Pause
