Git commit opens blank text file, for what?

Question

In all the Git tutorials I\'ve read they say that you can do:

git init
git add .
git commit

When I do that I get a big text file opened up.

Answer 1

If you’re on Mac OS X and using BBEdit, you can set this up as the editor of choice for commit messages:

git config --global core.editor "bbedit -w"

Once finished edit, save and close the file and git will use it for the comments.
