Running Metagoofil...
So, you opened it, by the KDE menu. Then, it opens the terminal window, where the text says "Example: -d".
Ok, let's try it.
When you type " -d", you have the logical response: "bash: command not found".
Ok, let's try it launching python... "python".
Oh, oh, surprise, there is the same text just like when you start the application! I mean, there's no way to do something with metagoofil...?¿?
