How to Install & Uninstall Git on Linux Ubuntu Os ?

Installing Git on Ubuntu is straightforward, but before diving into the installation process, it’s essential to ensure you meet the prerequisites to ensure a smooth and hassle-free setup.

Prerequisites to Install Git on Ubuntu:

1. A Running Ubuntu System: While this might sound obvious, make sure you have Ubuntu installed and running. Git can be installed on any supported Ubuntu version, although newer versions generally provide the latest Git releases.
2. Command-Line Access: You’ll need access to the terminal or command line interface (CLI) to install and configure Git. You can access the terminal via the Ubuntu application launcher or by pressing Ctrl + Alt + T.
3. Sudo Privileges: Installation requires administrative permissions. Ensure you have sudo privileges or know the root password. If you’re using a personal system, you likely already have sudo access with your user account.
4. Updated System: Before installing new software, it’s always a good practice to update your system’s package information. This ensures that you’re fetching the latest software versions and dependencies:

ubuntu@Rushi-InfoTech:~$ sudo apt-get update

6. Basic Command-Line Knowledge: While not strictly necessary, having basic knowledge of the Linux command line can be helpful. You’ll be using commands like apt for installation.

Once these prerequisites are in place, you can proceed with the Git installation on your Ubuntu system.

How to Install Git on Ubuntu ?

Update Your System

It’s a good practice to ensure your system’s package repository information is up-to-date before installing any new software. This ensures you’re getting the latest versions available.

Run the following commands to update your system:

ubuntu@Rushi-InfoTech:~$ sudo apt-get update

ubuntu@Rushi-InfoTech:~$ sudo apt upgrade -y

Press on "Enter"

Press on "Enter"

Successfully upgraded.

Install Git

With the system updated, installing Git is just one simple command away:

ubuntu@Rushi-InfoTech:~$ sudo apt install git -y

Press on "Enter"

Press on "Enter"

Verify the Installation

To ensure Git has been installed correctly, you can check its version:

ubuntu@Rushi-InfoTech:~$ git --version

This command should display the Git version installed, indicating that the installation was successful.

Initial Git Configuration

Now that Git is installed, you may want to configure your Git identity. This is important as every Git commit uses this information:

ubuntu@Rushi-InfoTech:~$ git config --global user.name "Your Full Name"
ubuntu@Rushi-InfoTech:~$ git config --global user.email "your_email@example.com"

Replace the placeholders with your actual name and email address.

Optional: Set Default Editor

If you have a preference for a specific text editor (like nano, vim, or emacs), you can set it as the default editor for Git:

ubuntu@Rushi-InfoTech:~$ git config --global core.editor vim

Replace vim with your preferred editor.

Git is now installed and configured on your Ubuntu machine. Whether you’re collaborating with a team or working on personal projects, Git provides a robust and efficient means of version control. As you grow more comfortable with Git, you’ll find that its versatility and power make it an indispensable tool in every developer’s arsenal. Happy coding!

How to Uninstall Git from Ubuntu:

Open the Terminal

You can launch the Terminal application either from the Ubuntu Dash or by pressing Ctrl + Alt + T.

Check the Installed Git Version

Before proceeding with the uninstallation, it’s a good idea to verify the version of Git you have installed:

ubuntu@Rushi-InfoTech:~$ git --version

This command will display the Git version if it’s installed.

Uninstall Git

To uninstall Git, you will use the apt package manager which comes with Ubuntu. Run the following command:

ubuntu@Rushi-InfoTech:~$ sudo apt remove --purge git

The --purge flag ensures that configuration and other auxiliary files related to Git are also removed.

Clean Up Unnecessary Packages

Whenever software is removed, there might be some orphaned packages left. You can clean them up using:

ubuntu@Rushi-InfoTech:~$ sudo apt autoremove

Update the Package Database

Finally, refresh your package database to make sure everything is up-to-date:

ubuntu@Rushi-InfoTech:~$ sudo apt-get update

Verify the Uninstallation

To ensure Git has been completely removed, you can once again try checking its version:

ubuntu@Rushi-InfoTech:~$ git --version

If Git has been uninstalled, the system should inform you that the git command was not found.

You’ve successfully removed Git from your Ubuntu system. If you ever need to reinstall it in the future, the process is straightforward using the Ubuntu package manager. Remember to always keep backups of your configurations and repositories to ensure you don’t lose valuable data when performing software maintenance tasks. Safe computing!
