If you need to move files in Ubuntu, the GUI based Nautilus is a big help. However, if you need to move files across user permissions, you need to run Nautilus as super user. I just figured out one way to do it:
- Open a Terminal window.
- Type “GKsudo” in the Terminal Window
- On the resulted window, type “nautilus”
- Supply your super user password.
Now you should see “root – File Browser” at the top. With file browser in root mode, you can move file across permission line!
