How about this?

# If no display has been specified, deduce local display number from X11 process.
if [ "$DISPLAY" = "" ]; then
export DISPLAY = `ps auxww | grep $USER | egrep '(Xauthority|/Applications/Utilities/X11.app/Contents/MacOS/X11 .*:[0-9]+$)' | grep -v grep | sed 's/^.*\(:[0-9][0-9]*\)$/\1/'` fi

(If you know where that code came from, you get a cookie!)

Smells of matlab.
