Easily Convert Ruby 1.8 to 1.9 hash syntax

You can easily convert your 1.8 hash rockets into cleaner, easier to read 1.9 hash syntax with this little script.

A single (ERB) file:

find . -name _file_upload.html.erb -exec ruby -i -p -e "gsub(/([^:]):(\w+)\s*=>/, '\1\2: ')" {} \;

or multiple (Ruby) files:

find . -name '*.rb' -exec ruby -i -p -e "gsub(/([^:]):(\w+)\s*=>/, '\1\2: ')" {} \;
