Lin, why are you putting 'sudo' in front of each command you are running? That is not necessary. In fact, there should be no need to run FS as root (which is what 'sudo' does). Also, depending on your setup, by typing 'sudo' you might in leave the FS environment for that command.
Try your commands without the 'sudo'...
