Maybe check -t STDIN  (would test if STDIN is opened to a tty) — see filetests

    Another option is to check if the DISPLAY env var is set, and open up graphical if it is.

    I think that's the behaviour things like emacs use for example. It does mean that if you open a console from your GUI and then start the program from there, it'll open up with the GUI, which seems to be slightly different from what you describe although more intuitive.

    (Update: "You" in the above means the OP of course, not almut)


      FYI: It's a frequent case where you have a console window open on an XTerm. Then you'd be on a console, but you'd still have DISPLAY set.
