How do I make Git use the editor of my choice for commits?

Question

I would prefer to write my commit messages in Vim, but it is opening them in Emacs.

How do I configure Git to always use Vim? Note that I want to do this globally,

Answer 1

In windows 7, while adding the "Sublime" editor it was still giving me an error:

Aborting commit due to empty commit message.

Sublime was not able to keep the focus.

To fix this I opened the .gitconfig file in c:/users/username/ folder and added the following line with --wait option outside the single quotes.

[core]
      editor = 'F:/Program Files/Sublime Text 2/sublime_text.exe' --wait

Hope its helpful to somebody facing similar issue with Sublime.
