Here there are some examples of git commands that I use often.
Not all commands written here are git commands, but all of them are related to git. Please refer to the documentation for more details.
git config --global user.name "John Doe"
git config --global user.email "[email protected]"
Use --global to set the configuration for all projects. If git config is used without --global and run inside a project directory, the settings are set for the specific project.
