10 Git commands for your day-to-day work

Git is a version control system which became a de-facto standard for many developers. Basically, any programmer nowadays is expected to know the basics of Git and understand how to work with this system. Therefore, in this article we’re going to list and discuss the most common and useful Git commands that you’re most likely going to utilize in your day-to-day work. We are going to see some examples and talk about the usage of these commands, so hold on tight, and let’s get started!


    To follow this article, you’ll need to have Git installed on your PC (obvious, isn’t it?). I’m going to use Git 2.32.0 which is the latest version at the time of writing this article.

    Apart from that, there are no special requirements: you can use any operating system and any command line tool.

    git init

    init is a Git command that initializes or reinitializes a Git repository in the current folder. So, after you have created a folder for your new shiny project, just cd into this folder and run:

    git init

    Basically, this command creates a hidden .git folder with all the Git goodies that are required to properly perform version control. This folder is very important as it’s going to store all history for your project therefore do not delete it unless you fully understand what you are doing.

    By default, git init creates a single “primary” branch in your project. Depending on your setup, this branch may be named either master or main. To override the primary branch name, provide the -b flag:

    git init -b primary

    Some terminology

    Before proceeding, let’s cover some common terms.

    • First of all, it’s important to understand that the changes that we perform are done in a so-called working tree of the project. Basically, the working tree is a collection of your files and folders (excluding files inside the .git folder) in their present state as they exist on the file system. You can freely create, modify, and delete files and folders in the working tree as usual. The working tree observes all your changes and makes notes of them.
    • An index (or “staging area”) is like a snapshot of your working tree that contains all the current changes. Simply speaking, it’s a large file inside the .git folder which contains all your files and their checksums.
    • When we perform a commit, the created snapshot is added to the project history. You can browse the created commits and even restore the previous versions of the files.
    • Branch is like an independent version of the same project stored in the same folder. You can switch between these independent versions, make changes as necessary, and at some point merge two versions together (or delete one of the versions completely). As the Git book says, “Branching means you diverge from the main line of development and continue to do work without messing with that main line”.

    File states

    Each file in a working tree can have the following states:

    • Untracked — a new file was added to the working tree but it’s not tracked by Git yet. You can start to track it by using git add command (see below).
    • Modified — the changes were made in the working tree but not yet staged for commit (in other words, these changes are not added to the current index).
    • Staged — the changes were added to the index. This way, they will become a part of the next commit.
    • Commited — the changes were added to the project history as a part of a commit. All commits are stored in the .git folder.

    Finally, here’s a nice explanation from the Git book that covers snapshots:

    Git doesn’t think of or store its data this way. Instead, Git thinks of its data more like a series of snapshots of a miniature filesystem. With Git, every time you commit, or save the state of your project, Git basically takes a picture of what all your files look like at that moment and stores a reference to that snapshot. To be efficient, if files have not changed, Git doesn’t store the file again, just a link to the previous identical file it has already stored. Git thinks about its data more like a stream of snapshots.

    Now that we know some terminology let’s discuss other useful Git commands!

    git status

    status shows, well, the status of your working tree. Specifically, you’ll be able to see your current branch, tracked and untracked files, as well as staged and unstaged changes:

    So, in the example above we can see that the current branch is master. The main.rb file is already tracked by Git and it has some changes that are not yet staged for commit (we will see how to achieve that a bit later).

    Also, we can see that the demo.rb is not yet tracked by Git.

    Here are some common options for the git status command:

    • -s — display output in short format.
    • -b — show the branch and tracking info in short format.
    • -v — show the textual changes that are staged to be committed. Here’s an example verbose output:

    Here you can see not only the filenames but also what exactly has changed in those files (new changes have green text color).

    git add

    add is probably one of the most common Git commands. So, what operation does it perform? Basically, it updates the index with the content found in your working tree thus making the content staged for the next commit. An index is like a snapshot of your working tree. When you perform a commit, this snapshot is utilized. Therefore, before doing a commit you should perform git add for any files that were modified or created.

    In the simplest case you can say:

    git add .

    This dot . means “take all the files in the working tree” and add them to the index.

    However, you can also add individual files and folders as well as use fileglobs:

    git add single_file.txt
    git add my_folder
    git add *.rb

    So, to summarize: after you have performed some changes in your project, you will need to run git add before doing a commit.

    This command accepts lots of different options which you can find in the official docs.

    git commit

    commit is one of the most important Git commands as it records the changes to the repository based on the current index (the snapshot that you’ve created).

    To perform a new commit and add a small informational message for it, run:

    git commit -m "My first commit"

    Now all the staged files will be commited and added to the project history.

    Also, you can use the -a option to automatically stage and then commit all the files that have been modified and deleted:

    git commit -am "My first commit"

    Unfortunately, this option will ignore untracked files, therefore you will still have to say git add . for these new files.

    git push/pull

    push Git command allows you to send local changes to the remote repository which is usually hosted on services like GitHub, Bitbucket, GitLab, or Azure DevOps repos.

    First of all, you will need to actually add information about this remote repository by running something like:

    git remote add origin

    Usually this command will be supplied to you by the service you’re using. What it does? It creates something like a “pointer” to a remote repository that is stored on This remote repository has an alias origin but you can call it anything you’d like (for example, just github).

    Now, when the remote repository is provided, you can push your local changes:

    git push origin master

    In this example we’re taking the contents of the master branch and push it to the remote repository which has an alias origin.

    You can also set origin as “upstream” by saying:

    git push -u origin master

    Now you don’t need to provide origin anymore. Just say:

    git push

    However, please note that it will work only for the master branch which was mentioned when creating an upstream — for all other branches you will still have to say:

    git push origin another_branch

    To grab changes from the remote repository and apply them locally, use:

    git pull origin master

    This command works in the same way as git push. If you have specified an upstream, you can simply say:

    git pull

    Please note that merge conflicts might occur and you will need to resolve them manually (check the next section about the  git merge command to learn about conflicts).

    git stash

    stash command saves all your modifications since the last commit, stores them away and returns to a clean working directory. In other words, if you have performed some modifications since the last commit but then decided that these modifications are not relevant anymore, you can run:

    git stash

    Now all the changes you’ve made will be stored separately, and the state of the project will be reverted to the last commit. You can create as many stashes as needed, and to view them run:

    git stash list

    Here’s the output:

    Two stashes were created in this example (stash@{1} was created before stash@{0}, in other words the first entry is the latest one).

    You can also view the contents of each stash:

    git stash show -p stash@{1}

    So, you can see what exactly was changed in this stash.

    If you decide to fetch your changes from a stash and apply them to the current version of the project again, run:

    git stash apply stash@{1}

    Now the changes will become visible in the current version of the project once again.

    git log

    log Git command displays commit logs and allows you to see what changes were made, when, and by whom:

    git log

    For each commit you can see:

    • Its checksum (that long alphanumeric string)
    • Author
    • Date
    • Commit message
    • The HEAD -> master means that the commit was performed on the master branch and this is the current version that we’re browsing at the moment.
    • develop means that the commit was performed on the develop branch.

    Provide the -p flag to view more detailed information:

    In this case you can see what exactly was changed in each commit (the first commit doesn’t show anything because we performed a merge).

    On top of that, you can provide a number in the following way:

    git log -p -2

    In this case 2 means “show me only the last two commits”.

    git branch

    branch is a Git command that enables you to manage project branches. A branch is basically a separate version of your project, and ability to work with different branches is one of most powerful features of Git. As already mentioned above, initially you are going to have only one “primary” branch but it’s possible to create as many branches as needed. Usually developers tend to create separate branches when implementing new features or introducing bug fixes — this is very convenient because this way they don’t mess with the main version of the application.

    To view all branches in your project, run:

    git branch

    Here’s the output:

    We can see that the project has two branches:

    • master which is the currently chosen branch.
    • develop — we can switch to this branch as needed.

    To create a new branch, run:

    git branch YOUR_BRANCH_NAME

    The new branch will be created based on the current version of your working tree. If you would like to create a branch based on some other version, you’ll have to provide the existing branch name and the new name:


    In this case the new branch will be created based on the existing branch that you have provided.

    To rename a local branch, run:

    git branch -m OLD_NAME NEW_NAME

    Alternatively, you can rename the current branch by running:

    git branch -m NEW_NAME

    To delete a local branch, run:

    git branch -d BRANCH_NAME

    Please note that in order to delete a remote branch, you’ll have to be a bit more verbose:

    git push origin --delete REMOTE_BRANCH_NAME

    git checkout

    checkout Git command allows you to switch between branches.

    In the simplest case you can say:

    git checkout BRANCH_NAME

    You will switch to a different branch and the corresponding version of the project will be loaded automatically for you.

    Also you can create a new branch based on the current one and switch to it in a single command:

    git checkout -b NEW_BRANCH_NAME

    In this case you’ll create a new branch based on the currently chosen one and also switch to it. Convenient, eh?

    On top of that, checkout has advanced usage which allows to travel back in history and even restore old versions of your files.

    git merge

    merge Git command joins development histories together. In other words, it allows you to take changes from one branch and incorporate it into another branch. For example, if you were implementing a new feature in the develop branch and want to incorporate these changes into the master, then you would run the following commands:

    git checkout master
    git merge develop

    After running these commands, all changes from the develop will be incorporated into master. However, if you modify the same lines in the sames files in both branches, then you would see a merge conflict:

    In this example there’s a merge conflict in the main.rb file. Here’s the output from the Visual Code editor:

    This conflict appeared because we’ve modified the same line in master and develop branches. Therefore, you have to pick one of the versions, delete the other version from your text file, and then commit the result:

    git commit -am "merged develop with master"

    Now the conflict is resolved and the merge operation is performed successfully.


    So, in this article we’ve discussed some common Git commands and their usage.
