Powershell如何关闭.exe进程

Question

I want to start a .exe file from powershell and wait for it to finish and then continue to the next line in the powershell. However after the .exe file finished it's job the window remain there to be manually closed. Just like notepad. Here is what I got

start-process -FilePath notepad -Wait -NoNewWindow
echo "it's done!"

I specified -NoNewWindow but it still comes with a window and the powershell have to wait until I manually close it. How can I close it automatically? The .exe file is a third party app that I have no control over.

Please note that I want to wait for the task that the .exe file completes and then automatically close that window so that I can continue to the next line in powershell.

I also tried -WindowStyle hidden.

start-process -FilePath notepad -Wait -WindowStyle hidden
echo "it's done!"

But this is even worse I have to go to task manager to kill the hidden window without knowing it is completed or not.

Is there a parameter better than -NoNewWindow that can force no new window show up?

Thanks,

This is what I use to kill iTunes automatically. But, as mentioned in my comment, if you want to wait for it to be done, you'd have to add either a sleep or do some application-specific check to see that its job is done. What that check is depends on what the exe is doing.

$itunesProc = Get-Process -name iTunes -ErrorAction "Ignore"
if ($itunesProc -ne $null) {
   echo "Stopping iTunes..."
   Stop-Process -Name iTunes
} else {
   echo "No running iTunes process found"
}

The script below will:

1. Open Notepad.
2. Wait for you to type "Finished".
3. Close Notepad.

You will need to install AutoIt . (I selected "x86" in the installer BTW.)

You will also need to adapt the Get-AU3ControlHandle call to suit your needs. The AutoIt Window Info Tool will be useful there. You may have to do some reading of the AutoIt documentation.

See also AutoIt Cmdlets for Windows PowerShell .

import-module "${env:ProgramFiles(x86)}\AutoIt3\AutoItX\AutoItX.psd1"
$p = Start-Process notepad -PassThru

# Wait for the window to open
while($p.MainWindowHandle -eq 0)
{
    Start-Sleep 1
}

$c = Get-AU3ControlHandle -WinHandle $p.MainWindowHandle -Control "Edit1"

while($true)
{
    $t = Get-AU3ControlText $p.MainWindowHandle $c

    if ($p.HasExited)
    {
        break;
    }
    elseif ($t -eq "Finished")
    {
        $p.CloseMainWindow();
        break;
    }
    else
    {
        Write-Output "Waiting 1 sec."
        Start-Sleep 1
    }
}

Write-Output "Done"
