I just did that, and you are true, it works.
But, when I do that with iceweasel, iceweasel is closed when I exit
the terminal... I guess I just do not understant at all the behavior
of the '&' and will need more reading.
berenger.morel,
The plot thickens. How did you exit the terminal? Did you File->Close
or type exit at the command prompt, or did you use a window manager
"close window" command (usually Alt+F4)? It makes a difference.
Yes, now I understand that it's different. I used my window manager
shortcut to close windows. With the exit command, it does not close, as
people here said, but this is something I would not had imagined. That
kind of threads remind me that I'm a real newbie in the linux world, I
like this!
