Mining web page content from the command line via node

gistfile1.sh

# traditional method of searching a website for content
#   curl contents of a web page, piped to grep to match regex
$ curl "foo.com" -Ls | grep -o bar

# proof of concept, piping to allow node.io to do the matching.
# node.io has a builtin eval method that uses javascript's eval
# to handle the matching
$ curl "foo.com" -Ls | node.io -s eval "input.match(/bar/g)"

# install node.io globally with npm
$ npm install -g node.io
