    It would be incredibly useful to see Debug.Log/Warning/Error messages when running a headless mode executable from the Terminal. Especially when running game servers, we don't really know what's going on or if there were any errors - unless we check the log files, which works, but is really annoying in the long run.

    I also attached a screenshot that shows the current output that is shown when running a headless mode executable in the terminal. Log messages are not shown there.

    [Tested on Linux Mint 17.2 Cinnamon, with latest Unity Linux build)

    Sorry if this is the wrong forum area, but I assumed that you guys take care of the Linux build part as well.

    You can watch the log file with the tail command:

    tail -f ~/.config/unity3d/Editor.log

    This will provide new output as soon as the log file updates.

    Thanks, that works!

    Having the output in the executable's log would still be much easier, especially when running game servers on a remote server etc.

    Hi! I have a similar problem: at that point if I close the terminal window, the server stops, how can I close it without stopping the server?

    Thank you for your time!

    This is just how the Linux/Unix terminal works, if you've started it using terminal, you have to keep the terminal open until the command is finished or stopped. One way to work around this might be to create a shell script to start your server and make it executable (chmod +x /path/to/shell/script.sh), then run it through your file manager. You could also create a .desktop file to run it instead. I can't currently guide you step by step (I'm on my phone), but you should be able to find all the necessary information through Google.

    Ok, thank you very much, reading your post gave me an idea and searching on Internet I found this: http://ubuntuforums.org/showthread.php?t=787417 , running the screen command and typing the following commands I am able to close the terminal.
    For now it's working.

    This is a good point, but you can also run with -logfile /dev/stdout (optionally piping to tee Editor.log)

    Hey, I run Ubuntu Desktop and Ubuntu Server. I use "screen" on my server and it's amazing. I am glad you found that option. It really can work well if you prefer to use the terminal for multiple programs.
