How to Set Up Git Username and Email on Ubuntu

Installing Git

Verifying Git installation on the machine precedes configuring usernames and emails. Opening the terminal and running this command handles missing installations:

sudo apt update
sudo apt install git

Configure Git Username and Email

Ready systems handle username and email configuration through 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

Ubuntu allows configuring Git usernames and emails for single project folders. Separate project requirements benefit from unique author details. Opening the project folder in the terminal and applying the 'git config' command assigns names and emails to that specific 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

Checking saved project settings on Ubuntu confirms correct configuration. Terminal execution provides direct verification. Running git config user.name displays the username while git config user.email reveals the email associated with that project.




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




Re-running the git config command with new values modifies existing settings when necessary.



Configuration complete.



Conclusion:




Configuring your Git username and email is crucial for ensuring proper attribution of your commits



The proper contact information associated with your commits can facilitate communication with other developers



Installing Git and configuring your username and email are essential steps for a smooth Git setup on Ubuntu Linux





Can we change Git config username and email?

Changing names associated with Git commits utilizes the git config command. Updated names appear on all subsequent commits pushed to GitHub from the command line.
