Wait for exit

I have the folling script that runs a batch file on a remote computer

$command = "c:\hello.bat"
$process = [WMICLASS]"\\$MachineName\ROOT\CIMV2:win32_process"  
$result = $process.Create($command)

How can I pause or wait to continue until this has completed?

assuming the process name created on the target machine is "cmd":

$command = "c:\hello.bat"
$process = [WMICLASS]"\\$MachineName\ROOT\CIMV2:win32_process"  
$result = $process.Create($command)
do {Start-Sleep -s 1} While ((Get-Process -Name cmd -computername $MachineName | Measure-Object).count -gt 0)

This seems to work but returns

Cannot find a process with the name "cmd". Verify the process name and call the cmdlet again.

Is this expected ?

yes, if after the process ends, the get-process will error because it is no longer running.

To suppress the error message, change the $ErrorActionPreference to “silentlycontinue”

$ErrorActionPreference = “silentlycontinue”
