How to know or change the git username and email through terminal?

To check if you have configured the git username and email on the local environment, use the following command:

1. Check git username and email

1.1 Method 1: use git command

$ git config --list
 

If you have configured username and email before, there you should find user.name and user.email.

If you haven’t configure a username and email, the outcome would looks like this:

1.2 Method 2: check the ‘~/.gitconfig’ file

$ cat ~/.gitconfig

2. check only git username or email

$ git config user.name
$ git config user.email

3. Configure or change user name and email

If you have not configured username and email before, you can use the following command:

$ git config --global user.name "yourName"
$ git config --global user.email "your@email.com"

Another way to change it is to edit the Git config file in your HOME directory and change it there:

vi ~/.gitconfig
