I want to know what "nautilus -q" command does in linux. As I use this command from Linux command line, all the icons from the desktop disappears and even no mouse click works upon desktop. When I restart the computer only then all icons appears on the desktop as usual. Is there any command in linux which causes reactivating and re-appear the desktop icons without restarting the computer after using nautilus -q. As far as I know , nautilus -q quits the nautilus. Plz, help me if anyone have any solution or details about natilus commands.
