Renaming the current file in Vim

Question

How should I rename my current file in Vim?

For example:

• I am editing person.html_erb_spec.rb
• I would like it renamed to person

Answer 1

• Write the file while editing - :w newname - to create a copy.
• Start editing the new copy - :e#.
• (Optionally) remove the old copy - :!rm oldname.

On Windows, the optional 3rd step changes a little:

• (Optionally) remove old Windows copy - :!del oldname.
