I asked a very similar question one week ago and I still try to find an answer.
I setup a complete new Unity3D project, put an object in it, create a C# script and put the following code in the Start() method.
void Start() {
Process myProcess = new Process();
myProcess.StartInfo.FileName = "gnome-terminal";
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.RedirectStandardInput = true;
myProcess.StartInfo.RedirectStandardOutput = true;
//myProcess.StartInfo.CreateNoWindow = true; for testing
myProcess.Start();
//Thread.Sleep(6000); somebody suggest wait some time, but it make no difference
myProcess.StandardInput.WriteLine("sensible-browser");
}
I build the project for my Linux Ubuntu system and execute it. A new terminal appears and that's it. Normally, now the browser should be open but it doesn't.
That's only my test program. In my origin one I have to read/write from/into the stdin/stdout.
I'm fully desperate and hopefully anyone of you can help me
Thanks
