How do I clone a single branch in Git?

Note: the git1.7.10 (April 2012) actually allows you to clone only one branch:

# clone only the remote primary HEAD (default: origin/master)
git clone <url> --single-branch

# as in:
git clone <url> --branch <branch> --single-branch [<folder>]

(<url> is the URL if the remote repository, and does not reference itself the branch cloned)

You can see it in t5500-fetch-pack.sh:

test_expect_success 'single branch clone' '
  git clone --single-branch "file://$(pwd)/." singlebranch
'

Tobu comments that:

This is implicit when doing a shallow clone. This makes git clone --depth 1 the easiest way to save bandwidth.

And since Git 1.9.0 (February 2014), shallow clones support data transfer (push/pull), so that option is even more useful now.
See more at "Is git clone --depth 1 (shallow clone) more useful than it makes out?".

"Undoing" a shallow clone is detailed at "Convert shallow clone to full clone" (git 1.8.3+)

# unshallow the current branch
git fetch --unshallow

# for getting back all the branches (see Peter Cordes' comment)
git config remote.origin.fetch refs/heads/*:refs/remotes/origin/*
git fetch --unshallow

As Chris comments:

the magic line for getting missing branches to reverse --single-branch is (git v2.1.4):

git config remote.origin.fetch +refs/heads/*:refs/remotes/origin/*
git fetch --unshallow  

With Git 2.26 (Q1 2020), "git clone --recurse-submodules --single-branch" now uses the same single-branch option when cloning the submodules.

See commit 132f600, commit 4731957 (21 Feb 2020) by Emily Shaffer (nasamuffin).

clone: pass --single-branch during --recurse-submodules Signed-off-by: Emily Shaffer Acked-by: Jeff King Previously, performing "git clone --recurse-submodules --single-branch" resulted in submodules cloning all branches even though the superproject cloned only one branch. Pipe --single-branch through the submodule helper framework to make it to 'clone' later on.

One way is to execute the following.

git clone user@git-server:project_name.git -b branch_name /your/folder

Where branch_name is the branch of your choice and "/your/folder" is the destination folder for that branch. It's true that this will bring other branches giving you the opportunity to merge back and forth.

Update

Now, starting with Git 1.7.10, you can now do this

git clone user@git-server:project_name.git -b branch_name --single-branch /your/folder

---

Using Git version 1.7.3.1 (on Windows), here's what I do ($BRANCH is the name of the branch I want to checkout and $REMOTE_REPO is the URL of the remote repository I want to clone from):

mkdir $BRANCH
cd $BRANCH
git init
git remote add -t $BRANCH -f origin $REMOTE_REPO
git checkout $BRANCH

The advantage of this approach is that subsequent git pull (or git fetch) calls will also just download the requested branch.

---

You can try the long-winded way:

mkdir newrepo.git
cd newrepo.git
git init
git remote add origin file:///path/to/original
git fetch origin branchiwant:refs/remotes/origin/branchiwant
git checkout -b branchiwant --track origin/branchiwant

What this does is:

Create and init an empty Git repository.

Adds the original repository as a remote called origin.

Fetches only the branch you require from the remote called origin.

Creates and checks out a new branch that is set up to track the source branch you just cloned.

Hopefully that will be something like what you are after.

---

git clone <url> --branch <branch> --single-branch

Just put in URL and branch name.

---

You can do it by using the below command:

git clone -b branch_name --single-branch project_url local_folder_to_clone_in

---

From git-clone man page:

--single-branch is your friend during clone remember to use with --branch <branch name> or only remote primary HEAD will be cloned (master by default)

Always remember to do Ctrl + F5 to read fresh source, not the one from cache :-) (I didn't so didn't know about this option for long time.)

---

Clone only one branch. This is the easiest way:

git clone -b BRANCH_NAME --single-branch git@bitbucket.org:___/PROJECTNAME.git

---

There are ample answers here which mention:

Download 1 branch (with the --single-branch part): # (We'll refer to this as "the 1st command" below.) # 1. Clone ONLY `branch_name`, then check it out. The `--single-branch` part # means that ONLY `branch_name` is cloned, fetched, pulled, and # tracked. _No other remote branches will be cloned to your PC # whatsoever._ git clone -b branch_name --single-branch \ https://github.com/some_project/some_project.git ...or some version of that, and a few which mention just: Download all branches (withOUT the --single-branch part): # (We'll refer to this as "the 2nd command" below.) # 2. Clone ALL remote branches, then `git checkout` the `branch_name` # branch. git clone -b branch_name \ https://github.com/some_project/some_project.git

But, I'd like to expound upon these two things a bit and show a more familiar set of equivalent commands so we can see what is happening with each under-the-hood.

Let's assume that you have a remote repo on GitHub at https://github.com/micronucleus/micronucleus.git, with remote branches master and version_2.5 (this is a real example you can actually run right now).

Breakdown of the 2nd command from above:

The 2nd command (git clone -b version_2.5 https://github.com/micronucleus/micronucleus.git) clones ALL REMOTE BRANCHES to your local PC, but then checks out the version_2.5 branch instead of the master branch. That one command is the equivalent of doing this:

git clone https://github.com/micronucleus/micronucleus.git
cd micronucleus  # cd into the repo you just cloned
git checkout version_2.5
# To be pedantic, also delete the local `master` branch since
# technically it won't exist yet since you haven't yet checked
# it out with `git checkout master`, which would create it from
# your locally-stored remote-tracking branch, `origin/master`
git branch -d master

The -b version_2.5 part automatically checked out the version_2.5 branch for us instead of master.

git branch -a shows us that ALL branches, however, were cloned to our local PC. Here you can see our local branch version_2.5, which we are on, plus the locally-stored remote-tracking branches origin/HEAD (which points to origin/master), plus origin/master, and origin/version_2.5:

$ git branch -a
* version_2.5
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
  remotes/origin/version_2.5

We can also look at what our fetch references are. You can either open up the .git/config file to see them directly, or just run git config remote.origin.fetch:

$ git config remote.origin.fetch
+refs/heads/*:refs/remotes/origin/*

You can see above that our git fetch command (which is also triggered by git pull since that is equivalent to git fetch && git merge) is configured to fetch ALL heads for ALL branches in the origin remote. I'm not an expert on this part, but I believe that's what +refs/heads/*:refs/remotes/origin/* means.

Breakdown of the 1st command from above:

The 1st command (git clone -b version_2.5 --single-branch https://github.com/micronucleus/micronucleus.git) clones ONLY the version_2.5 branch to your local PC, and it also checks it out. That one command is the equivalent of doing this (in the end result at least, except that it also downloads much less data in the beginning since it only clones ONE branch NOT all of them):

git clone https://github.com/micronucleus/micronucleus.git
cd micronucleus  # cd into the repo you just cloned
git checkout version_2.5

# Delete ALL other branches, including remote-tracking ones, which are not the 
# `version_2.5` branch:
# One local branch
git branch -d master
# ALL other locally-stored remote-tracking branches
git branch -dr origin/HEAD 
git branch -dr origin/master

# Fix your `.git/config` file so that `git fetch` does the right thing, fetching
# ONLY the `version_2.5` branch head from the `origin/version_2.5` remote branch:
git config remote.origin.fetch \
"+refs/heads/version_2.5:refs/remotes/origin/version_2.5"

The -b version_2.5 part caused the version_2.5 branch to be checked out instead of the master branch by default (as previously explained above), and the --single-branch part caused:

NONE of the other branches to be cloned to our PC, and git fetch to be configured such that NONE of the other branches will ever be fetched when we call git fetch or git pull!

This command truly cloned and will fetch only the one branch we wanted, and that's it!

git branch -a shows us that ONLY the version_2.5 branch was cloned and checked out. Here we see by the * which branch is checked-out, and we see also that we have a locally-stored remote-tracking branch for origin/version_2.5:

$ git branch -a
* version_2.5
  remotes/origin/version_2.5

We can also look at what our fetch references are. You can either open up the .git/config file to see them directly, or just run git config remote.origin.fetch:

$ git config remote.origin.fetch
+refs/heads/version_2.5:refs/remotes/origin/version_2.5

You can see above that our git fetch command will only fetch the version_2.5 branch head from the origin/version_2.5 remote branch. That's it! Beware that no other remote branches will ever be fetched.

Summary:

So, now you see that using -b branch_name basically just ensures the branch_name branch is checked-out after the clone, but still clones ALL remote branches, whereas adding also --single-branch ensures that ONLY branch_name is cloned, fetched, pulled, and tracked. No other remote branches will be cloned to your PC whatsoever.

Personally, I prefer the -b branch_name option alone, because I want all branches cloned to my local PC. The one exception might be on a huge, shared mono-repo which has dozens, or even hundreds or thousands of remote branches. In that case, just use -b branch_name --single-branch to clone just the one main branch you care about and be done. Better to download 50 GiB of data for the master branch in a huge mono-repo, for instance, than to download 200 GiB of data so you can have 2000 of your peers' branches they are working on too!

Clone only one branch How do you stop tracking a remote branch in Git?

---

For cloning a specific branch you can do :

git clone --branch yourBranchName git@yourRepository.git

---

For cloning a branch of Git you don't have the public key to, use this:

git clone -b <branch> <Git repository URL or clone URL you get from Git repository>

---

A little late but I wanted to add the solution I used to solve this problem. I found the solution here.

Anyway, the question seems to be asking 'how to start a new project from a branch of another repo?'

To this, the solution I used would be to first create a new repo in github or where ever. This will serve as the repo to your new project.

On your local machine, navigate to the project that has the branch you want to use as the template for your new project.

Run the command:

git push https://github.com/accountname/new-repo.git +old_branch:master

What this will do is push the old_branch to new-repo and make it the master branch of the new repo.

You then just have to clone the new repo down to your new project's local directory and you have a new project started at the old branch.

---

Let us take the example of flask repo. It has 3 branches in addition to master. Let us checkout the 1.1.x remote branch

clone the git repo

git clone https://github.com/pallets/flask

cd into the repo.

cd flask

fetch remote branch 1.1.x

git fetch origin 1.1.x

checkout the branch

git checkout 1.1.x

You will switch to the branch 1.1.x and it will track the remote 1.1.x branch.

---

Open the cmd.

cd folder_name  # enter the path where to clone the branch

Just one command:

git clone url_of_projecturltoclone -b branch_name

---

There are primarily 2 solutions for this:

You need to specify the branch name with -b command switch. Here is the syntax of the command to clone the specific git branch. git clone -b Example: git clone -b tahir https://github.com/Repository/Project.git The following command will clone the branch tahir from the git repository.The above command clones only the specific branch but fetches the details of other branches. You can view all branches details with command. git branch -a You can use --single-branch flag to prevent fetching details of other branches like below: git clone -b --single-branch Example: git clone -b tahir --single-branch \ https://github.com/Repository/Project.git Now if you do a git branch -a, it will only show your current single branch that you have cloned and not all the branches. So it depends on you how you want it.

🏎️ Some Performance Measurements 🏎️

I compared two of the suggested approaches, and found that one is way faster (and smaller) than the other (which is advantageous if your only goal is to clone, and you don't care about much else).

I found that the most important performance indicator is --depth, meaning that VonC's answer is the fastest. Try it yourself:

time bash -cl "git clone --single-branch --depth=1 --branch=$MYBRANCH $MYGITURL"

I tested this with a big project with a long history and many branches, and this approach takes about 6s.

Note that, contrary to what is claimed by several comments in this thread, (at least in a recent git version), this will only checkout the target branch. git branch -a only lists that single branch.

The Runner Up

By comparison, frerich-rabe's approach consistently took 26s:

time bash -cl "git init && git remote add -t $MYBRANCH -f origin $MYGITURL && git checkout $MYBRANCH"

When comparing the two, it is also important to note that, in my case, the target branch is a much slimmed down version of its parent branch. The first approach's download progress bar reflects that reduction in size (< 10MB), while the second does not (> 90MB). (I'm sure, there are more mature methods to measure total download size, but I have not looked into that yet.)

If you want a shallow clone, you can do this with:

git clone -b mybranch --depth=1 https://example.com/myproject.git localname

--depth=1 implies --single-branch.

---

you can use this command to git single branch and rename the folder if you want to keep branched stand alone

git clone -b [branch-name] --single-branch [url]  [folder_name]

example

git clone -b mybranch --single-branch git://github/repository.git  project_mybranch

---

This should work

git clone --single-branch <branchname> <remote-repo-url>
git clone --branch <branchname> <remote-repo-url>

---

I did it this way

git clone -b url

example :

git clone -b master https://gitlab.com/jhondoe/applicationproject.git

or

git clone -b master git@gitlab.com:jhondoe/applicationproject.git

---

git clone --single-branch -b [branch name]  [repository URL]

---

git clone --branch <branchname> <remote-repo-url>

or

git clone -b <branchname> <remote-repo-url>

---

git clone --branch {branch-name} {repo-URI}

Example:

git clone --branch dev https://github.com/ann/cleaningmachine.git

dev: This is the {branch-name}

https://github.com/ann/cleaningmachine.git: This is the {repo-URI}

---

Similar to what @nosaiba-darwish said here: here

This is what we usually do in our company:

git clone -b <name_of_branch> --single-branch <git_url> folder_to_clone_locally

---

For the newbies like me, just run the code below

git clone https://gitlab.com/repo/repo.git --branch <name of branch> --single-branch

---

Can be done in 2 steps

Clone the repository git clone Checkout the branch you want git checkout $BranchName

---
