Git fetch remote branch

The remote contains various branches such as origin/daves_branch:

$ git branch -r
origin/HEAD -> origin/master
origin/daves_branch
origin/master

How do I checkout daves_branch locally so that it tracks origin/daves_branch? I tried:

$ git fetch origin discover
$ git checkout discover
possible duplicate of git checkout remote branch
I used: git fetch --all, Then to view all the branches: git branch, Then I checkout the branch: git checkout nameofnewbranch
git fetch origin discover:discover && git checkout discover

Update: Using Git Switch

All of the information written below was accurate, but a new command, git switch has been added that simplifies the effort.

If daves_branch exists on the remote repository, but not on your local branch, you can simply type:

git switch daves_branch

Since you do not have the branch locally, this will automatically make switch look on the remote repo. It will then also automatically set up remote branch tracking.

Note that if daves_branch doesn't exist locally you'll need to git fetch first before using switch.

Original Post

You need to create a local branch that tracks a remote branch. The following command will create a local branch named daves_branch, tracking the remote branch origin/daves_branch. When you push your changes the remote branch will be updated.

For most recent versions of Git:

git checkout --track origin/daves_branch

--track is shorthand for git checkout -b [branch] [remotename]/[branch] where [remotename] is origin in this case and [branch] is twice the same, daves_branch in this case.

For Git 1.5.6.5 you needed this:

git checkout --track -b daves_branch origin/daves_branch

For Git 1.7.2.3 and higher, this is enough (it might have started earlier, but this is the earliest confirmation I could find quickly):

git checkout daves_branch

Note that with recent Git versions, this command will not create a local branch and will put you in a 'detached HEAD' state. If you want a local branch, use the --track option.

Full details are here: 3.5 Git Branching - Remote Branches, Tracking Branches


"git fetch" to make sure your repo is updated with remote references and "git checkout --track origin/discover" should be enough. Then you can commit to that branch and a "git push" to sync the remote with your changes.
I tried this and got "fatal: git checkout: updating paths is incompatible with switching branches. Did you intend to checkout 'upstream/develop' which can not be resolved as commit?". Am I doing something wrong?
Looks like git 1.5.6.5 needs this instead: git checkout --track -b origin/daves_branch
This made a mess for me, it created a local branch named origin/ which is now ambiguous to the remote branch origin/ and I don't know how to get rid of the crazy local branch!
You need to add the local branch name explicitly, otherwise git creates a new local branch with the full branch path, as @AlanMoore and @derekmx271 stated above: git checkout -b --track daves_branch origin/daves_branch

I have used fetch followed by checkout...

git fetch <remote> <rbranch>:<lbranch>
git checkout <lbranch>

...where <rbranch> is the remote branch or source ref and <lbranch> is the as yet non-existent local branch or destination ref you want to track and which you probably want to name the same as the remote branch or source ref. This is explained under options in the explanation of <refspec>.

Bash is so smart it auto completes the first command if I tab after the first few letters of the remote branch. That is, I don't even have to name the local branch; Bash automatically copies the name of the remote branch for me. Thanks, Bash!

Also as the answer in this similar Stack Overflow post shows, if you don't name the local branch in fetch, you can still create it when you check it out by using the -b flag. That is, git fetch <remote> <branch> followed by git checkout -b <branch> <remote>/<branch> does exactly the same as my initial answer. And evidently, if your repository has only one remote, then you can just do git checkout <branch> after fetch and it will create a local branch for you. For example, you just cloned a repository and want to check out additional branches from the remote.

I believe that some of the documentation for fetch may have been copied verbatim from pull. In particular the section on <refspec> in options is the same. However, I do not believe that fetch will ever merge, so that if you leave the destination side of the colon empty, fetch should do nothing.

NOTE: git fetch <remote> <refspec> is short for git fetch <remote> <refspec>: which would therefore do nothing, but git fetch <remote> <tag> is the same as git fetch <remote> <tag>:<tag> which should copy the remote <tag> locally.

I guess this is only helpful if you want to copy a remote branch locally, but not necessarily check it out right away. Otherwise, I now would use the accepted answer, which is explained in detail in the first section of the checkout description and later in the options section under the explanation of --track, since it's a one-liner. Well... sort of a one-liner, because you would still have to run git fetch <remote> first.

FYI: The order of the <refspecs> (source:destination) explains the bizarre pre Git 1.7 method for deleting remote branches. That is, push nothing into the destination refspec.


This worked for me to get the remote code into a local branch. It did not however get my local branch to track the remote branch.
For some reason, git fetch remote branch didn't add a branch head at all for me, though all the refs got fetched, so when I tried to follow the steps in the accepted answer, I got the error that pathspec did not match any file(s) known to git., but the rbranch:lbranch approach worked. Interestingly, it also fetched all the tags that started with the same prefix, like it is a wildcard (rbranch*).
Nit: git doesn't do the autocompleting, it is the bash shell that is doing it.
FWIW, I think the difference between this answer and the accepted answer is that this one tells you to do the fetch command. It the accepted answer makes sense though because OP notes that he already did the fetch. That's at least the issue I ran into.
Hi @Honey, as the answer above states: "And evidently if your repo has only one remote, then you can just do git checkout <branch> after fetch and it will create a local branch for you. EG: You just cloned a repo and want to check out additional branches from the remote." Also in the git-checkout docs: "If <branch> is not found but there does exist a tracking branch in exactly one remote (call it <remote>) with a matching name, treat as equivalent to: $ git checkout -b <branch> --track <remote>/<branch>"

If you are trying to "checkout" a new remote branch (that exists only on the remote, but not locally), here's what you'll need:

git fetch origin
git checkout --track origin/<remote_branch_name>

This assumes you want to fetch from origin. If not, replace origin by your remote name.


Usually, I use git fetch, but the thing is what is the difference between git fetch and git fetch origin ?
@PingWoo Assuming that the branch you want to fetch resides in origin remote, both git fetch and git fetch remote will do the same thing. If you need to fetch from a remote other than origin, you could do that using git fetch <other_remote_name>. This situation is highly uncommon, just mentioned here for completeness.
i get fatal: 'fusedwm/fuse_keybindings-setborderpx-alphabar-transparency-monrules-nowarpresize' is not a commit and a branch 'fuse_keybindings-setborderpx-alphabar-transparency-monrules-nowarpresize' cannot be created from it

To checkout myBranch that exists remotely and not a locally - This worked for me:

git fetch --all
git checkout myBranch

I got this message:

Branch myBranch set up to track remote branch myBranch from origin
Switched to a new branch 'myBranch'

In other words you don't have to write -t?
I think there's an error in this answer. I originally did the command without -t and got You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. because there wasn't a local branch of the same name. I had to re-run with -t to fix.
This worked well for me - my colleague had added a new remote branch that I wanted to add to my local repo. I kept fetching but didn't see the new branch appearing locally. Didn't realize that I could just run checkout for it to create it. Thanks!
depends on git versions. Latest version, as said elsewhere here, only needs git checkout . BE CAREFUL WITH SAME-NAME LOCAL vs REMOTE BRANCHES - they will mess stuff up
--all is never a good idea, because it will download every file on every branch. It will take more time and space. It's better to be specific with the branch name and do like this

fetch the branch locally:

git fetch origin <branchName>

move to that branch:

git checkout <branchName>

Does not bring other branches
@BenjaminHarel the question says "fetch a remote branch" not all branches. for that follow this may be helpfull for you stackoverflow.com/questions/10312521/…
After using this fetch command required branch will be available on local machine. git checkout -b 'your_branch' origin/'remote branch' is required to checkout this branch.

Peter Mortensen

Use git branch -a (both local and remote branches) or git branch -r (only remote branches) to see all the remotes and their branches. You can then do a git checkout -t remotes/repo/branch to the remote and create a local branch.

There is also a git-ls-remote command to see all the refs and tags for that remote.


git checkout remotes/repo/branch makes git checkout look for a pathspec, not a remote repo.
Yes, is it even possible to checkout a branch on the remote repo? Obviously (or maybe it wasn't so obvious), remotes are first fetched so that you have them locally. The git book has a good section on them: git-scm.com/book/en/Git-Branching-Remote-Branches
git checkout -t remote_branch_name is probably the most simple and laziest way out of all answers.

The title and the question are confused:

Git fetch remote branch

how can my colleague pull that branch specifically.

If the question is, how can I get a remote branch to work with, or how can I Git checkout a remote branch?, a simpler solution is:

With Git (>= 1.6.6) you are able to use:

git checkout <branch_name>

If local <branch_name> is not found, but there does exist a tracking branch in exactly one remote with a matching name, treat it as equivalent to:

git checkout -b <branch_name> --track <remote>/<branch_name>

See documentation for Git checkout

For your friend:

$ git checkout discover
Branch discover set up to track remote branch discover
Switched to a new branch 'discover'

Thanks Guillaume! I just used this command and wrote a post about it to depict my exact case: leniel.net/2014/05/…
works as expected, Thanks Guillaume!

To fetch a branch that exists on remote, the simplest way is:

git fetch origin branchName
git checkout branchName

You can see if it already exists on remote with:

git branch -r

This will fetch the remote branch to your local and will automatically track the remote one.


How does this question not have more upvotes? I could be wrong but this sure seemed to do the trick, fetched a branch I didn't have on local from remote...

Use:

git checkout -b serverfix origin/serverfix

This is a common enough operation that Git provides the --track shorthand:

git checkout --track origin/serverfix

In fact, this is so common that there’s even a shortcut for that shortcut. If the branch name you’re trying to checkout (a) doesn’t exist and (b) exactly matches a name on only one remote, Git will create a tracking branch for you:

git checkout serverfix

To set up a local branch with a different name than the remote branch, you can easily use the first version with a different local branch name:

git checkout -b sf origin/serverfix

Now, your local branch sf will automatically pull from origin/serverfix.

[Quick Answer]

There are many alternatives, and my favourites are:

- Alternative 1:

git fetch --all
git checkout YourBranch

Using this alternative using a branch that exist remotely, but not in your local.

- Alternative 2:

git checkout -b 'YourBranch' origin/'YourRemote'

Probably, this is the simplest way.

What helped me was

1) To view all available remote branches (e.g. 'remote-branch-name')

git branch -r

2) Create a local branch using remote branch name

git fetch && git checkout 'remote-branch-name'

What happens when you run the command git push without any other arguments? Is the local branch named remote-branch-name automatically associated with (tracking to) the remote branch named origin/remote-branch-name. Or do you need to run git push -u origin remote-branch-name
this will cause HEAD detached state

You can fetch and checkout the remote branch in one shot too:

I typed

git checkout <branch_name>

and got

Branch <branch_name> set up to track remote branch <branch_name> from origin.
Switched to a new branch '<branch_name>'

from git checkout documentation: If <branch_name> is not found but there does exist a tracking branch in exactly one remote with a matching name, treat as equivalent to: git checkout -b <branch_name> --track <remote>/<branch_name>

At times you are asked not to fiddle with the master branch and work only the remote branch (as I was asked to). So all you need is the remote branch.

So to clone the remote branch alone (without the master), do this

git clone url --branch remote_branch_name

where, remote_branch_name is the name of the remote branch

For example,

git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git --branch v3.15

This will make sure that you clone the remote branch to your local branch with the name of the remote branch.

Now if you commit your code and push, the code will be submitted to that branch alone.

The steps are as follows;

git fetch origin or git fetch --all , this will fetch all the remote branches to your local and then this the second option you can proced with. git checkout --track origin/

Then work on this branch and you can verify whether you are on that branch or not by typing

git branch

It displayes the branch you currently in.

Peter Mortensen

Simply try:

git pull origin your_branch_name

Rizo, git pull origin branch_name should be the best solution. You are the only person that posted this as a solution and it worked for me. This works because it will update your branch with the master branch. simple and uncomplicated.
the problem with this is that it will try to merge that remote branch with your CURRENT branch, which is not the remote one (since that is new for your local repo)
This will merge to your current branch.

Let's say that your remote is git@xyz.git and you want its random_branch branch. The process should be as follows:

First check the list of your remotes by git remote -v If you don't have the git@xyz.git remote in the above command's output, you would add it by git remote add xyz git@xyz.git Now you can fetch the contents of that remote by git fetch xyz Now checkout the branch of that remote by git checkout -b my_copy_random_branch xyz/random_branch Check the branch list by git branch -a

The local branch my_copy_random_branch would be tracking the random_branch branch of your remote.

If you would like to fetch all remote branches, please type just:

git fetch --all

If you have a repository that was cloned with --depth 1 then many of the commands that were listed will not work. For example, see here

% git clone --depth 1 https://github.com/repo/code

In this case I would reclone the repository, but perhaps there are other techniques e.g. git shallow clone (clone --depth) misses remote branches

git fetch && git checkout <your friend's branch name> should do the trick


P

I want to give you one-liner command for fetching all the remote branches to your local and switch to your desired newly created local branch:

git fetch && git checkout discover

After running the above command you will get the below message:

Switched to a new branch 'discover'
Branch discover set up to track remote branch discover from origin.

The first line states that switched to a new branch - why new? It is already there in remote!

But actually you have to create it locally too. The branch is taken from the remote index and created locally for you.

Here discover is a new branch which were created from your repository's remote branch discover.

But the second line gives more information than the first one which tell us that:

Our branch is set up to track remote branch with the same name.

Although git fetch fetches all branches to local. But if you run git branch after it, you will see only master branch in local. Why?

Because for every branch you have in remote you have to create it locally too, for tracking it as git checkout <branchname> as we have done in the above example.

After running git checkout command you can run git branch, and now you can see both the branch:

master and 2. discover in your local listing.


P
Peter Mortensen

Check your .git/config file, particularly what tracking is present on fetch for that remote.

[remote "randomRemote"]
    url = git@github.com:someUser/someRepo.git
    fetch = +refs/heads/*:refs/remotes/randomRemote/*

If it has heads/* pointing to randomRemote/*, when you run git fetch randomRemote, it will fetch all branches.

Then you can just checkout that branch.

Otherwise,

You need to add remote branches to the tracking using this. Check your .git/config after running this. You will understand. git remote set-branches --add randomRemote randomBranch Run git fetch randomRemote. This will fetch the remote branch. Now you can run git checkout randomBranch.


P
Peter Mortensen

If you already know your remote branch like so...

git remote
=> One
=> Two

and you know the branch name you wish to checkout, for example, br1.2.3.4, then do

git fetch One
=> returns all meta data of remote, that is, the branch name in question.

All that is left is to checkout the branch

git checkout br.1.2.3.4

Then make any new branches off of it.

You use 'git pull' to keep your branches separate. I will use the actual repository and branch names to help since 'lbranch' and 'rbranch' are tough to decipher.

Let's use:

myteam.unfuddle.com = the remote Git server

tlc = Unfuddle project account where the repository exists

daves_branch = remote branch name You, or any colleague, can run this to pull only your branch, no matter how many branches there are: git init git pull git@myteam.unfuddle.com:myteam/tlc daves_branch:refs/remotes/origin/daves_branch

Peter Mortensen

A simple command, git checkout remote_branch_name will help you to create a local branch that has all the changes in the remote branch.


S

If you download the repository with git clone <repo_url> -b <branch> (only cloning certaing branch), you should modify the <repo_name>/.git/config file. Replace or modify the line that references the fetch target of the [remote "origin"] section to let the command git fetch --all discover all branches:

[remote "origin"]
        url = <repo_git_url>
        fetch = +refs/heads/master:refs/remotes/origin/master

Be sure to set the fetch parameter point to /heads/master.

Care with git fetch --all because this will fetch all, so may take a long time.
