我可以从启动流程而不是CMD流程获得实际的咕unt声吗？

Question

I'm using

Start-Process grunt -ArgumentList 'serve' -PassThru

and add it to an ArrayList . When I view said ArrayList it shows cmd process, not actual node.js process that was launched. If I try to Stop-Process it, quite obviously, kills cmd process, not the running grunt . I can locate running grunt with Get-Process node .

The problem is I need multiple grunts running at the same time and I want a way to distinguish between them somehow. Is there any way I can get actual node process into PowerShell upon initializing it?

Answer 1

This happens because grunt is launched via grunt.cmd which is run by CMD . This file launches grunt in node .

Here is an example of how to find notepad2.exe launched from a CMD similarly to your example:

# start a CMD which starts notepad2 and then waits on it
$process = Start-Process -PassThru 'cmd.exe'  '/c "C:\Program Files\Notepad2\Notepad2.exe"'

# Wait for notepad2 to be launched
Start-Sleep -Seconds 2

# find the children of CMD, and kill the one which is notepad2
(Get-CimInstance win32_process -Filter "ParentProcessId='$($process.Id)' AND Name = 'Notepad2.exe'")  | %{ Stop-Process  -Id $_.ProcessId}

Translating this for grunt:

# start Grunt via grunt.cmd
$process = Start-Process grunt -ArgumentList 'serve' -PassThru

# Wait for node to be launched
Start-Sleep -Seconds 2

# find the children of CMD, and kill the one which is node
(Get-CimInstance win32_process -Filter "ParentProcessId='$($process.Id)' AND Name = 'node.exe'")  | %{ Stop-Process  -Id $_.ProcessId}

Answer 2

grunt isn't a Win32 executable, it's a javascript file that's run by node.exe . The easiest way to get the instance of node that's running grunt would be to start it yourself:

$ps = start-process -passthru  node -argumentlist "$env:APPDATA\npm\node_modules\grunt\bin\grunt"
