When pushing multiple refs, we know any Git objects on the remote side can be excluded from the objects that refer to LFS objects we need to push, since if the remote side already has the Git objects, it should have the corresponding LFS objects as well. However, when traversing Git objects, we traverse them on a per-ref basis, which is required since any LFS objects which spawn a batch request will need the ref to be placed in the batch request as part of the protocol. Let's find a list of all the remote sides that exist before traversing any Git objects, and exclude traversing any of those objects in any traversal. As a result, we can traverse far, far fewer objects, especially when pushing new refs in a large repository. Note that we exclude the case when the left and right sides are the same because our code sets them to the same thing in some cases even though Git does not, so we cannot reason about the values in that case. |

Git Large File Storage
Git LFS is a command line extension and specification for managing large files with Git.
The client is written in Go, with pre-compiled binaries available for Mac, Windows, Linux, and FreeBSD. Check out the website for an overview of features.
Getting Started
Downloading
You can install the Git LFS client in several different ways, depending on your setup and preferences.
- Linux users. Debian and RPM packages are available from PackageCloud.
- macOS users. Homebrew bottles are distributed, and can
be installed via
brew install git-lfs. - Windows users. Git LFS is included in the distribution of Git for Windows. Alternatively, you can install a recent version of Git LFS from the Chocolatey package manager.
- Binary packages. In addition, binary packages are available for Linux, macOS, Windows, and FreeBSD.
- Building from source. This repository can also be built from source using the latest version of Go, and the available instructions in our Wiki.
Installing
From binary
The binary packages include a script which will:
- Install Git LFS binaries onto the system
$PATH - Run
git lfs installto perform required global configuration changes.
$ ./install.sh
From source
- Place the
git-lfsbinary on your system’s executable$PATHor equivalent. - Git LFS requires global configuration changes once per-machine. This can be done by running:
$ git lfs install
Example Usage
To begin using Git LFS within a Git repository that is not already configured for Git LFS, you can indicate which files you would like Git LFS to manage. This can be done by running the following from within a Git repository:
$ git lfs track "*.psd"
(Where *.psd is the pattern of filenames that you wish to track. You can read
more about this pattern syntax
here).
Note: the quotation marks surrounding the pattern are important to prevent the glob pattern from being expanded by the shell.
After any invocation of git-lfs-track(1) or git-lfs-untrack(1), you must
commit changes to your .gitattributes file. This can be done by running:
$ git add .gitattributes
$ git commit -m "track *.psd files using Git LFS"
You can now interact with your Git repository as usual, and Git LFS will take
care of managing your large files. For example, changing a file named my.psd
(tracked above via *.psd):
$ git add my.psd
$ git commit -m "add psd"
Tip: if you have large files already in your repository's history,
git lfs trackwill not track them retroactively. To migrate existing large files in your history to use Git LFS, usegit lfs migrate. For example:$ git lfs migrate import --include="*.psd" --everythingFor more information, read
git-lfs-migrate(1).
You can confirm that Git LFS is managing your PSD file:
$ git lfs ls-files
3c2f7aedfb * my.psd
Once you've made your commits, push your files to the Git remote:
$ git push origin master
Uploading LFS objects: 100% (1/1), 810 B, 1.2 KB/s
# ...
To https://github.com/git-lfs/git-lfs-test
67fcf6a..47b2002 master -> master
Note: Git LFS requires at least Git 1.8.2 on Linux or 1.8.5 on macOS.
Limitations
Git LFS maintains a list of currently known limitations, which you can find and edit here.
Need Help?
You can get help on specific commands directly:
$ git lfs help <subcommand>
The official documentation has command references and specifications for the tool.
You can always open an issue, and one of the Core Team members will respond to you. Please be sure to include:
- The output of
git lfs env, which displays helpful information about your Git repository useful in debugging. - Any failed commands re-run with
GIT_TRACE=1in the environment, which displays additional information pertaining to why a command crashed.
