I'm using a MacOS X. I know that this code in the terminal will replace all txt files that include "hello" with "hiThere" in the folder named "world":

perl -pi -w -e 's/hello/hiThere/g;' ~/Desktop/world/*.txt

But inside that world folder there are other folders which have other txt files in them, and those don't go through the refactor or the rename, you have to then individually type the additional folders using the above method.

Is there a method that does it automatically for you?

Use this :

find main_dir -type f -name '*.txt' -exec perl -pi -w -e 's/hello/hiThere/g;' {} \;

Replace main_dir by your main directory
