What does Please Tell me who you are in git mean?

Question

I am totally new in this area of technology, I am following a course but I stopped. When I try to give a git commit -m "commit inicial" the string message in git is this:

Author identity unknown

*** Please tell me who you are.

Run

  git config --global user.email "[email protected]"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'Kleber@Kleber-PC.(none)')

From here do not know what to do and how to arrange so that it does not appear again, could help me please? Thanks

Answer 1

That means Git doesn’t know who you are. To work it needs an Email and a name to identify you.

But why?

Git uses your email address to associate your name with any commit of your own. After submitting your commits to a public repository on Github, for example, authorship metadata is also published. This means that whoever accesses your repository will be able to see that it was you who made X changes to the code and not someone else.

How to solve?

Let’s assume that your Email is [email protected].
You will need to type in these two commands that are necessary to identify you, rest assured that this step you will only need to do once:

git config --global user.email "[email protected]"
git config --global user.name "Kleber"

Done this the error will be fixed.
