Whenever I try to execute shell commands, I get an error saying 

/bin/hostname: /bin/hostname: cannot execute binary file
fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[0]
      An unhandled exception has occurred: Index was outside the bounds of the array.

I currently have

public MachineData FindHostname()
{
        Thread.Sleep(3000);
        ProcessStartInfo psi = new ProcessStartInfo();
        psi.FileName = "/bin/bash";
        psi.Arguments = "/bin/hostname && /bin/uname";
        psi.UseShellExecute = false;
        psi.RedirectStandardOutput = true;

        Process proc = new Process
        {
            StartInfo = psi
        };

        proc.Start();
        ...
}

Does anyone know of a workaround?

    If you try it from command line you'll see it doesn't work and has nothing to do with ASP.NET. You need to give bash the -c flag to run commands Commented Aug 15, 2016 at 20:24

    You can also use the UseShellExecute = true setting. It can be used for exactly this kind of scenario; wanting to run a command through the shell... :) Commented Jan 21, 2017 at 12:48
  • I'm sorry but how will it work. I didn't get it. Any elaborated answer. In my case I'm providing -c but it still gives an error Commented Aug 16, 2017 at 10:13
