10 Git Commands Every Programmer Should Learn

Git is a powerful version control system that is essential for any programmer. In this article, we will introduce you to 10 Git commands that every programmer should learn in 2024. From creating and managing repositories to adding and committing changes, these commands will help you collaborate with other developers and improve your productivity. 

Whether you’re a beginner just starting out with Git or an experienced programmer looking to expand your skills, these commands are worth learning.


    1. git init

    The git init command is used to initialize a new Git repository. This is the first command you should run when you start a new project with Git. It creates a .git subdirectory in your project, which stores all the information about your repository, including the history of your changes, including the HEAD file, the objects directory, and the refs directory. 

    Here is an example of git init command from a directory myproject
    $ cd myproject
$ git init

    After running this command you can check that .git directory has been created or not. 


    2. git add

    The git add command is used to add files to the staging area. When you make changes to your code, you need to tell Git which changes you want to include in the next commit. You do this by using the git add command to add the changed files to the staging area.

    Here is an example of git add command:

    $ git add file1.txt
$ git commit -m "Initial commit"


    3. git commit

    The git commit command is used to save your changes to the Git repository. When you run this command, Git will take all the changes that are in the staging area and create a new commit with those changes. Each commit has a unique identifier, called a hash, which allows you to track the changes that were made in that commit.

    Here is an example of git commit command:

    4. git push

    The git push command is used to send your commits to a remote repository, such as GitHub. When you run this command, Git will upload your commits to the remote repository, allowing other developers to access them.

    Here is an example of git push command:

    git push example



    5. git pull

    The git pull command is used to fetch and merge changes from a remote repository. When you run this command, Git will download any new commits from the remote repository and merge them into your local repository. This is a useful command when you’re working on a team. 

    Here is an example of git pull command:

    git pull example


    6. git clone

    The git clone command is used to create a local copy of a remote repository. When you run this command, Git will download the entire repository, including all the commits and branches, to your local machine. This is a useful command when you want to work on an existing project or contribute to an open-source project.

    Here is an example of git clone command:

    git push example



    7. git branch example

    The git branch command is used to create, list, and delete branches. Branches are used to develop new features or make changes to your code without affecting the main branch. When you create a new branch, Git creates a copy of the main branch at the current commit, allowing you to make changes without affecting the main branch.

    Here is an example of git branch command:

    git branch example



    8. git checkout example

    The git checkout command is used to switch between branches or restore files to a previous commit. When you run this command with the name of a branch, Git will switch to that branch. When you run it with the hash of a commit, Git will restore the files to the state they were in at that commit.

    Here is an example of git checkout command:

    git checkout example


    9. git merge example

    The git merge command is used to merge changes from one branch into another. When you run this command, Git will take the changes from the source branch and apply them to the target branch, creating a new commit in the process. This is a useful command when you want to bring the changes from one branch into the main branch.

    Here is an example of git merge command, thanks to ChatGPT:

    git merge example


    And, if you need code here it is:

    git merge code example


    10. git stash example

    The git stash command is used to save changes temporarily without committing them. When you run this command, Git will take all the changes that are in the staging area and save them in a stash.

    You can later apply the stash to a branch using the git stash apply command. This is a useful command when you need to switch branches or restore files to a previous commit but don’t want to commit your changes.

    Here is an example of git stash command:

    git stash example
