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][page] for a high level overview of features.

分布式版本控制系统Git在版本控制大文件上有所欠缺，基于Git的代码托管平台Github宣布了扩展Git Large File Storage (LFS)， 改进了大文件的版本控制，允许开发者在工作流中整合大的二进制文件如音频样本、数据集和视频。Git LFS暂时只提供给部分挑选出来的用户组，未来几个月每个托管库将默认支持Git LFS。免费用户的Git LFS有限额，文件储存限制在1GB，每月带宽流量1GB。用户可付费增加储存空间和流量。

Getting Started

Download the [latest client][rel] and run the included install script. The installer should run git lfs init for you, which sets up Git’s global configuration settings for Git LFS.

Note: Git LFS requires Git v1.8.2 or higher.

Configuration

Git LFS uses .gitattributes files to configure which are managed by Git LFS. Here is a sample one that saves zips and mp3s:

$ cat .gitattributes
*.mp3 filter=lfs -text
*.zip filter=lfs -text

Git LFS can manage .gitattributes for you:

$ git lfs track "*.mp3"
Tracking *.mp3

$ git lfs track "*.zip"
Tracking *.zip

$ git lfs track
Listing tracked paths
    *.mp3 (.gitattributes)
    *.zip (.gitattributes)

$ git lfs untrack "*.zip"
Untracking *.zip

$ git lfs track
Listing tracked paths
    *.mp3 (.gitattributes)

Pushing commits

Once setup, you’re ready to push some commits:

$ 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
