Have you ever needed to perform a find and replace operation that spans across numerous files in your project? Doing this operation file by file can be tedious. Searching for an answer to this issue can be frustrating due to the involvement of many different Unix tools, each with their own flags. Some of these flags are incompatible between Linux and OS X, so it can quickly devolve into plugging in a solution, and moving on when it fails.
