Docker

Remove stopped containers:

docker rm $(docker ps --all --quiet --no-trunc --filter 'status=exited')

Remove unused images:

docker rmi $(docker images --quiet --filter 'dangling=true')

Git

Slightly modified answer from “Make the current commit the only (initial) commit in a Git repository” on Stack Overflow:

git checkout --orphan newBranch
git add --all  # Add all files and commit them
git commit --message="Initial commit."
git branch --delete --force master  # Deletes the master branch
git branch --move master  # Rename the current branch to master
git push --force --set-upstream origin master  # Force push master branch to github
git gc --aggressive --prune=all     # remove the old files
