Learning GIT Masterclass - Lesson 3 - Configuring your GIT Identity - Setting your username & email

Now that you have Git up and running on your system, you might want to do a couple of things to customise your Git environment. You ought to do these things only once per given computer; they’ll stick around between upgrades. You can also change them at any time by running through the commands again.

Git comes equipped with a special tool called git config that lets you set and retrieve your configuration variables that how Git looks and operates.

Git configuration (initial configuration)
# your name and email address
$ git config --global user.name "Eduard"
$ git config --global user.email [email protected]

# more optional git config stuff
$ git config --global core.editor vim
$ git config --global merge.tool vimdiff

# GIT Configuration Files
GIT also write to this file:
/etc/gitconfig file: Contains values for every user on the system and all their repositories.

Global settings are put in this file:
~/.gitconfig file: Contains values for the same user on the system and all their repositories.

Local settings are placed in the Git configuration file in your current Git repository. See this file in your repository:
.git/config file: Contains values for only a user on the user and only for the local repository

Each level overrides values in the previous level, so values in .git/config trump those in /etc/gitconfig.

You can check your Git configuration using commands like these:
# show all git configurations
$ git config --list

# show a specific key
$ git config user.name
