I'm new to PowerShell. Found how to display the PID of the process being started:

[Diagnostics.Process] :: Start ("calc"). Id> out.txt

Is it possible to start the application by passing the arguments to it? Next, output to the file out.txt both the PID itself and the result of the process?

  • possible if the application accepts arguments - Senior Pomidor

    Senior Automator, I think your answer is correct. Attaches several examples about PS scripts at once, especially when you open the first time and do not know the syntax. But from the documentation I collected this option:

     (Start-Process .\Data\myprog.exe -ArgumentList '-param1 value1','-param2 value2','-param3 value3' -RedirectStandardOutput result-myprog.txt -PassThru -NoNewWindow).Id > result-pid.txt

    What ultimately creates two files containing the necessary information, without dancing with a tambourine.
