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

:sav newfile | !rm #

Note that it does not remove the old file from the buffer list. If that's important to you, you can use the following instead:

:sav newfile | bd# | !rm #
