How to Set Up Git Username and Email on Ubuntu

Installing Git

Verify that Git is installed on your machine before configuring your username and email. Opening the terminal and running this command handles missing installations:

sudo apt update
sudo apt install git

Configure Git Username and Email

You can configure your username and email right from the terminal using the git config command.

Settings apply globally or per repository. Running the git config command with the --global option establishes global commit names and email addresses.

Setting your Global Username

Open the terminal.

Run this command to set a global Git username:

git config --global user.name "User_name" 

Substitute "Your Name" with the preferred name or username for Git commits.

Setting your Global Email Address

Run this command in the terminal to set a global email address (replacing your_email@example.com with the actual address):

git config --global user.email "your_email@example.com" 

Substitute "your_email@example.com" with the actual email address linked to the Git or GitHub account.

Setting Username and Email for a Single Repository

You can set a different Git username and email for a single repository on Ubuntu without changing your global settings. This is useful when you want to use a work email for one project and a personal email for another. Open your terminal, go to your project folder, and use the git config command to save your details just for that project.

Navigate to the project directory:

cd path/to/your/project 

Set the local username for this repository:

git config user.name "Project Specific Name" 

Set the local email address for this repository:

git config user.email "project_specific_email@example.com" 

Verifying your Configuration

Checking settings via the git config --list command follows username and email configuration.

git config --list

Output displays all Git configuration settings. Locating user.name and user.email verifies the configurations.

Checking Global Configuration

git config --global user.name
git config --global user.email

Checking Local Configuration

You can check your saved local Git settings on Ubuntu to make sure your username and email are correct before you make any commits. Open your project folder in the terminal and run specific git config commands to view the author details attached to that exact project so your work is always credited properly.




Correct information finalizes the Git setup process. Subsequent commits automatically apply the configured username and email address.
