Git Large File Storage

Linux	macOS	Windows

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 Git LFS website for an overview of features.

Getting Started

By default, the Git LFS client needs a Git LFS server to sync the large files it manages. This works out of the box when using popular git repository hosting providers like GitHub, Atlassian, etc. When you host your own vanilla git server, for example, you need to either use a separate Git LFS server instance, or use the custom transfer adapter with a transfer agent in blind mode, without having to use a Git LFS server instance.

You can install the Git LFS client in several different ways, depending on your setup and preferences.

• Linux users can install Debian or RPM packages from PackageCloud. See the Installation Guide for details.
• Mac users can install from Homebrew with brew install git-lfs, or from MacPorts with port install git-lfs.
• Windows users can install from Chocolatey with choco install git-lfs.
• Binary packages are available for Windows, Mac, Linux, and FreeBSD.
• You can build it with Go 1.8.1+. See the Contributing Guide for instructions.

Note: Git LFS requires Git v1.8.5 or higher.

Once installed, you need to setup the global Git hooks for Git LFS. This only needs to be done once per machine.

$ git lfs install

Now, it's time to add some large files to a repository. The first step is to specify file patterns to store with Git LFS. These file patterns are stored in .gitattributes.

$ mkdir large-repo
$ cd large-repo
$ git init

# Add all zip files through Git LFS
$ git lfs track "*.zip"

Now you're ready to push some commits:

$ git add .gitattributes
$ git add my.zip
$ git commit -m "add zip"

You can confirm that Git LFS is managing your zip file:

$ git lfs ls-files
my.zip

Once you've made your commits, push your files to the Git remote:

$ git push origin master

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 ask questions in the Git LFS chat room, or file a new issue. Be sure to include details about the problem so we can troubleshoot it.

1. Include the output of git lfs env, which shows how your Git environment is setup.
2. Include GIT_TRACE=1 in any bad Git commands to enable debug messages.
3. If the output includes a message like Errors logged to /path/to/.git/lfs/objects/logs/*.log, throw the contents in the issue, or as a link to a Gist or paste site.

See CONTRIBUTING.md for info on working on Git LFS and sending patches. Related projects are listed on the Implementations wiki page. You can also join the project's chat room.

Using LFS from other Go code

At the moment git-lfs is only focussed on the stability of its command line interface, and the server APIs. The contents of the source packages is subject to change. We therefore currently discourage other Go code from depending on the git-lfs packages directly; an API to be used by external Go code may be provided in future.
