It's really easy to quickly search certain files in a large directory for some text.
find -name "*.html" -or -name "*.json" -or -name "*.js" | xargs grep -i "full_uri"
The "find" command searches out those specific files.
The "xargs grep" will search the files (-i makes it case insensitive).
Now its much easier to find your stuff, even with a million lolcats swarming the place.
