If you are a developer, it is very likely that you have encountered the "Please tell me who you are" error message while using Git. This error is usually caused by an incorrect or missing Git identity configuration. Git identity is essential because it helps you to identify the author of the commits you make. In this guide, we will show you how to set your Git identity to avoid the "Please tell me who you are" error.
Before we get started, you need to have Git installed on your system. If you do not have Git installed, you can download it from the official Git website (https://git-scm.com/downloads).
Setting Your Git Identity
To set your Git identity, you need to configure your name and email address. Here are the steps to do this:
Open your terminal or command prompt.
Type the following command to set your name:
git config --global user.name "Your Name"
Replace "Your Name" with your actual name.
Type the following command to set your email address:
git config --global user.email "[email protected]"
Replace "[email protected]" with your actual email address.
Verify that your Git identity has been set correctly by typing the following command:
git config --list
This command will display your Git configuration, including your name and email address.
