lucky.rb outputs a link to the top hit on Google for a given search string. I wrote it to use in MacOS X with Automator + Services so that I could have a global keyboard shortcut that would replace a string with its "I'm Feeling Lucky" result-- handy for writing blog posts, comments, etc. Usage: lucky.rb [options] query1 query2 ... --credentials FILE A file containing a Google API key and referrer URL -f, --format FORMAT The output format (url, html, or markdown) -k, --key KEY:URL API key and referrer URL (overrides credentials file) -h, --help Display this screen To use lucky.rb, you'll need to have an API key to use the AJAX API.
