Works great with Gist: The Website.
Updated to work with Ruby 1.9.
curl http://github.com/tsion/gist/raw/master/gist.rb > gist && chmod 755 gist && sudo mv gist /usr/local/bin/gist
gist < file.txt echo secret | gist --private # or -p gist 1234 > something.txt
Just have your git config set up with your GitHub username and token.
git config --global github.user "your-github-username" git config --global github.token "your-github-token"
You can find your token under your account.
