Git config account information

When we use git on a server first time, it will report the following error if we didn’t set the email and name:*** Please tell me who you are.Rungit config --global user.email "you@example.com"
 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: empty ident name (for <username@servername.(none)>) not allowed

We can use git config --global user.email to set the email to the global scope, we can also omit the --global to set the email only for the current repository.

Unset the global config, we can use --unset option like this:git config --global --unset user.email

The config file

The git config settings were saved on file, the global config file is ~/.gitconfig , the repository config file is ./.git/config .
