Basic Unix Skills

While using vi as the superuser, saving a file while exiting the editor produces an error that the file is read-only. How can the file permissions be overridden so the edits are saved and the editor is exited?

Explanation

In vi, :wq! forces the file write despite the editor's read-only warning and then quits. As superuser, the underlying operating-system permissions allow the forced write to succeed.
