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, not just for a single project.

If you want to set the editor only for Git 

Set core.editor in git config: git config --global core.editor "vim"

Set the git-editor environment variable to export GIT_EDITOR=vim

If you need to set editor not only for git but also for other programs use following standardized visual and editor environmental variables 

export VISUAL=vim

export EDITOR="$VISUAL"

For sublime text: add the following to git.config file

[core]

    editor = 'subl' --wait

--wait is compulsory which allows you to type and will wait to save/close the event.
