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

The git commit command will open up the editor specified in the EDITOR environment variable so you can enter a commit comment. On a Linux or BSD system, this should be vi by default, although any editor should work.

Just enter your comments and save the file.
