git-lfs-demo

Demo Repo for Git LFS. Ryan will use this to demonstrate how to use Git LFS with big files.

Fork the repo, then clone it.

Get the repo.

git clone https://github.com/<your_name>/git-lfs-demo.git
cd git-lfs-demo/

Make a big file and track with Git LFS.

git checkout -b make_data_file
seq 1000000 > big_file.dat
git-lfs track big_file.dat

Push to server.

git add .gitattributes
git add big_file.dat
git commit -m "Added big file."
git push origin make_data_file

Be sure to go complete the PR on Github.

Make new branch to change file.

git checkout main
git branch -D make_data_file
git pull
git checkout -b change_data_file

Change the file however you want. I moved some rows around using vim.

Push the changed file.

git diff
git add big_file.dat
git commit -m "Changed big file."
git push origin change_data_file

DO NOT complete this PR on Github, yet.

Clone a new version of the repo and make a conflicting change.

cd /tmp
git clone https://github.com/<your_name>/git-lfs-demo.git
mv git-lfs-demo/ git-lfs-demo_KYLE
cd git-lfs-demo_KYLE
git checkout -b change_file_differently

Change the file in a different way, here. I'm adding a header row.

Push to Github to see merge conflict.

git add -A
git commit -m "Added a header to data file."
git push origin change_file_differently

Open a PR to main and see the conflict. Notice the diff uses Git LFS hashes and not the huge file contents.
