Unity headless mode

Unity Engine

I’m trying to run a “server” version of my game in headless mode on linux. I make the build (and mark the “headless” box) and am able to run the app. However, I need for the app to be able to detect that it is running on the server. My first thought was to have a function like:

bool IsServer()
  {
    string[] args = System.Environment.GetCommandLineArgs();

    return Array.IndexOf(args, "--server") > 0;
  }

And then running the app like “./appname_x86_64 -nographics -batchmode -logfile log.txt --server”. The app launches, but it doesn’t seem to run as a server (but I’m not sure how to tell if it got the correct result from the IsServer() call.

So two questions, firstly is this a good way to detect if it is running on the server? Secondly, is there a way for me to output something to log.txt so I can debug a little? Something like Debug.Log() but that prints out in log.txt so I can tell how my code ran / what points it got to.

Bumping this question as I also want to do something very similar
