Adding this sed command to the deploy script

Hello,

I have a small section of sed code I would like to add to the

deploy.rb script.

The code changes the image paths of our stylesheets

for file in *; do
sed -e ‘s//images/http://cache.reverbnation.com/images/g’
“$file” > “${file}.sub”
rm “$file”
mv “${file}.sub” “${file}”
done

I am a newbie at writing and testing rake tasks and would like to know
what the best way to test this before it goes live?

Thanks,
Clem C Rock
