Recursively grep while specifying sub directory

I have a directory structure that looks something like this:

/home/states/Alabama
/home/states/Alaska
/home/states/Arizona

Within each state subdirectory, I have several more sub directories that look something like:

/home/states/Alabama/drink
/home/states/Alabama/food
/home/states/Alabama/fun

I want to grep for a keyword and my command looks like this:

grep -R "string" –include=*.cfg *

How can I specify the subdirectory within a state, so I only want to grep within the food directory within each state?

>Solution :

Use a wildcard to specify the path:

grep -R 'string' /home/states/*/food/*.cfg
