TIL: How to Grep For a String In .cfc File Type

Need to change a variable name across 50 files in 10 folders? Here's how to grep for that variable in .cfc files:

grep -r -i --include \*.cfc 'wirebox' modules

What a neat trick! I googled this today and couldn't believe my awesome luck. The last time I had to do this I think I used locate, like this:

locate -type f -name '*.cfc' modules| grep -i 'wirebox'

As you can see, the grep --include \*.cfc is a far cleaner syntax.
