Trying to start a new process in a separate command prompt on Windows 10, but can't find how to execute commands in opened prompt. With Powershell, I could use -Command:

Start-Process PowerShell "-Command tasklist"

But how to do that in Command Prompt window? This, obviously, doesnt work:

Start-Process cmd '-Command tasklist'

    Have you tried cmd /? for help? The option you're looking for is /C Commented Aug 10, 2021 at 17:24

You're using the PowerShell arguments for cmd.exe. cmd /? will give you the usage, but what you want is cmd /c COMMAND [ARGUMENTS]:

Start-Process cmd "/c ping -n 4 google.com"

@Jeff Zeitlin was kind enough to provide a link to the SS64 CMD usage.

Worth mentioning, you don't need to use Start-Process when running external commands unless:

  • You are running a GUI application and wait to use the -Wait parameter to wait until the program exits
  • You want to run something in a different process asynchronously and check the result later
    • In this case don't forget to use -PassThru and assign the process to a variable, so you can check the result when ready
