Using Git LFS

Background

Git Large File Storage (LFS) is supported on CodeArts Repo. It stores large file such as music, images, and videos outside a Git repository while users can still easily perform operations on these files as if they were within the repository. The Git extension allows more repository space and faster repository cloning, and reduces the impact of large files on the Git performance.
If the size of a file to be uploaded exceeds 200 MB, use Git LFS.
Get started with Git LFS:

Installing Git LFS

The following table describes the installation on different operating systems.

**Table 1** Installing Git LFS
Operating System	Installation Method
Windows	Download and install Git 1.8.5 or a later version. Run the following command in the CLI: git lfs install
Linux	Download the installation package from PackageCloud for your operating system and CPU architecture. Decompress the installation package, run the install.sh script to install the software, and then run the following command to check whether the installation is successful: git lfs version
macOS	Install the Homebrew software package management tool, and run the following commands: $ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" $ brew install git-lfs $ git lfs install

Configuring File Tracking

This section describes how to configure file tracking.

**Table 2** Configuring file tracking
Scenarios	Method
Track all .psd files	Run the following command: git lfs track "*.psd"
Track a file	Run the following command: git lfs track "logo.png"
View tracked files	Run git lfs track or view the .gitattributes file. $ git lfs track Listing tracked patterns .png (.gitattributes) .pptx (.gitattributes) $ cat .gitattributes .png filter=lfs diff=lfs merge=lfs -text .pptx filter=lfs diff=lfs merge=lfs -text

Table 2 Configuring file tracking

Scenarios

Method

Track all .psd files

Run the following command:

git lfs track "*.psd"

Track a file

Run the following command:

git lfs track "logo.png"

View tracked files

Run git lfs track or view the .gitattributes file.

$ git lfs track
Listing tracked patterns
    *.png (.gitattributes)
    *.pptx (.gitattributes)
$ cat .gitattributes
*.png filter=lfs diff=lfs merge=lfs -text
*.pptx filter=lfs diff=lfs merge=lfs -text

Committing Large Files

The .gitattributes file should be pushed to the repository along with the large files. After the push, run git lfs ls-files to view the list of track files.

$ git push origin master

Run git lfs clone to clone a remote repository that contains Git LFS files to the local computer.

$ git lfs clone <URL>
