## How to run Shell commands from GitHub with help of Curl and shortened Git.io URLs [github]

# With help of GitHub web UI create public repository (repository name: `REPO`) under 
#   your GitHub user account (user name: `USER`). This results in Git repository URL
#   of `https://github.com/USER/REPO.git`

# Initialize local Git repository and create, commit, and push to the `master` branch 
#   (or other one) a file (file name: `run`) with shell commands you'd like to run
git init
git remote add origin https://github.com/USER/REPO.git

# we are going to fetch all branches and tags from GitHub 
#   repo 'repo-to-fetch' and push them to GitHub repo 'repo-to-push'
#   - 'repo-to-fetch' is supposed to be public available GitHub repo
#     under the user account 'public-acc'
#   - 'repo-to-push' is newly created GitHub repo the user account 
#     'push-acc' has write access to

# create dir and init it as bare git repo
mkdir bare-repo
cd bare-repo
