-- this will try and find the Terminal.app window containing a particular tty and raise it above almost all other windows. I would like it to raise the lone window above all others, but I still don't know how to do that. ( http://apple.stackexchange.com/questions/39204/script-to-raise-a-single-window-to-the-front )

You ever have the problem where you issue a command, and it lasts longer than a few seconds, so that you tab away to a browser or something, and you lose track of what you were doing?

Put one piece in .bash_profile and another piece in your home directory. When a command takes longer than some threshold, this will beep and try to raise the window (if Terminal.app).

It will also beep on concluding interactive programs like less or an editor, which is kind of annoying but eh.
