  • Terminal: Git is a command-line tool, which means that you need to use the terminal to interact with it. If you are not familiar with the terminal, you may want to learn some basic commands before proceeding with the installation.

  • Dependencies: Git has a few dependencies that need to be installed before you can install Git itself. These dependencies include curl, gettext, and libssl-dev. We will cover the installation of these dependencies in the next section.

  • Admin rights: In order to install Git and its dependencies, you need to have administrative privileges on your Ubuntu system. If you are not the admin, you may need to contact your system administrator to install Git for you.

By ensuring that you meet these , you can ensure a smooth installation process and be able to use Git to manage your code effectively.

Installation of Git on Ubuntu 20.04

If you're planning on working with Git, then the first step is to install it on your machine. This process is relatively simple and can be done using the command line in Ubuntu 20.04 with a few simple commands.

Here's a step-by-step guide to installing Git on Ubuntu 20.04:

  1. Open the terminal window by pressing Ctrl+Alt+T keys.

  2. Type the following command to update the package lists:

    $ sudo apt update
  3. Once the package lists are up to date, install Git using the following command:

    $ sudo apt install git
  4. Verify that Git is installed by running the following command:

    $ git --version

    This command should return the version of Git that you have installed on your machine.

Congratulations! You have successfully installed Git on your Ubuntu 20.04 machine.

Now that you have Git installed, you're ready to start using it for version control and collaboration on your projects.

Configuring Git on Ubuntu 20.04


Before using Git, you need to configure it with your user information. This is crucial as Git uses this information to identify who is committing changes to the repository. Here is a step-by-step guide to :

  1. Open the Terminal application by pressing Ctrl+Alt+T, or search for it using the Ubuntu Dash search bar.

  2. Type the following command to set your name, replacing YOUR_NAME with your actual name:

    git config --global "YOUR_NAME"
  3. Type the following command to set your email address, replacing YOUR_EMAIL_ADDRESS with your actual email address:

    git config --global "YOUR_EMAIL_ADDRESS"
  4. (Optional) If you want to use a specific text editor instead of the default editor, type the following command, replacing YOUR_TEXT_EDITOR with the name of the text editor you want to use:

    git config --global core.editor "YOUR_TEXT_EDITOR"

    For example, to use Gedit, you can type git config --global core.editor "gedit -w -s"

That's it! Now Git is configured with your user information, and you can start using it to manage your repositories.

Basic Git commands with practical examples

Git is a version control system that allows programmers to keep track of changes made to their code over time. Here are some basic Git commands that you can use to get started:

git init

This command initializes a Git repository in the current directory.

$ git init

git add

This command adds files to the staging area, which is where files are placed before they are committed.

$ git add file.txt

git commit

This command creates a snapshot of the changes that have been made to the files in the staging area.

$ git commit -m "added file.txt"

git status

This command displays the status of the Git repository, including which files are staged, unstaged, and untracked.

$ git status

git log

This command displays a list of all the commits that have been made to the repository.

$ git log

git branch

This command shows a list of all the branches in the repository.

$ git branch

git checkout

This command is used to switch between branches or to create a new branch.

$ git checkout -b new_branch

These are just a few of the basic Git commands that you can use to manage your code. With practice, you will become more comfortable with Git and be able to use more advanced commands to unlock its full potential.

Branching and merging in Git

In Git, branching refers to creating multiple copies of the codebase to work on different features or versions simultaneously without affecting the master branch. Merging, on the other hand, is the process of joining two or more branches together to incorporate changes from one branch into another.

Creating a New Branch

To create a new branch in Git, use the git branch command followed by the name of the new branch:

$ git branch feature-branch

This will create a new branch called feature-branch. To switch to this branch and start working on it, use the git checkout command:

$ git checkout feature-branch

Committing Changes

Once you have made changes to the code in a branch, you can commit those changes using the git commit command:

$ git add .
$ git commit -m "added new feature"

This will add all changes to the staging area and commit them with the message "added new feature".

Merging Branches

To merge changes from one branch into another, switch to the branch that you want to merge changes into and use the git merge command:

$ git checkout master
$ git merge feature-branch

This will merge any changes from feature-branch into master. If there are any conflicts between the two branches, Git will prompt you to resolve them before the merge can be completed.


Branching and merging are powerful features of Git that allow developers to work on code in multiple versions or features at the same time without disrupting the main codebase. By understanding how to create and merge branches, you can simplify the development process and ensure that changes are implemented smoothly and effectively.

Working with remote repositories in Git

In Git, we use remote repositories to collaborate with other developers on a project. A remote repository is basically the same as a local repository, but it is stored on a different server than your local machine. This allows multiple developers to work on the same project and easily share their code changes with one another.

Here are some common tasks you might perform when :

  • Cloning a remote repository: To clone a remote repository, you use the git clone command followed by the URL of the remote repository. This will create a copy of the remote repository on your local machine that you can work on.

  • Fetching changes from a remote repository: To fetch changes from a remote repository (i.e., to get the latest code changes from other developers), you use the git fetch command. This will download the latest changes to your local machine, but it will not merge them with your local branch.

  • Merging changes from a remote repository: When you're ready to merge changes from a remote repository into your local branch, you use the git merge command. This will merge the changes from the remote branch with your local branch.

  • Pushing changes to a remote repository: To push your code changes to a remote repository (i.e., to share your changes with other developers), you use the git push command. This will send your code changes to the remote repository so that other developers can access them.

In order to work with remote repositories in Git, you'll need to have permission to access them. This usually involves either having administrative access to the remote server, or being granted permission by someone who does. Additionally, you may need to configure Git to authenticate with the remote repository using your username and password.

Overall, is an essential part of collaborating on code with other developers. By mastering the techniques outlined above, you'll be well on your way to becoming a proficient Git user!
