Step 1

In this step, we are going to look at the environment and see how to view & update the configuration.

Display the git client version:

git version

Look at the available git commands:

git help

List all configuration:

git config -l

Set your identity (you can update it)

git config --global user.name "John Doe"
git config --global user.email johndoe@example.com

Set default branch name:

git config --global init.defaultBranch main

List at the updated configuration:

git config -l

You can also look at one configuration in particular:

git config user.name

Finally look at where it is stored

more $HOME/.gitconfig
