## 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

cat > run << _EOF
#!/bin/sh
set -e
echo "Hello World"
_EOF

git add run
git commit -m "init+cmd"
git push -u origin master

# With help of GitHub web UI get 'raw' link to the commited file, for `master`
#   branch it should be: `https://raw.githubusercontent.com/USER/REPO/master/run`

# Setup `git.io` shorten URL by specifying your own code
curl -i https://git.io \
  -F "url=https://raw.githubusercontent.com/USER/REPO/master/run" \
  -F "code=vanity-command"

# Now you can run the commands with 
curl -sL https://git.io/vanity-command | bash
