It's easy to convert a shell script to a Mac App as suggested here. But I am only able to see the operation result of the script(or the Mac App) after the script finished and there seem to be no easy way to see the standard output as we would do when launching the script in terminal. Currently I am directing the standard output to a text file and view the file with some editor like sublime text. But I don't like the way I am doing it and looking for some more decent way. Is there any chance I can launch a terminal to display the standard output?
