Finding words in scripts over folders

Issue

You have a lot of scripts in a folder (or folders), and you want to find the ones containing specific words.

Here is an example.
I have a lot of python scripts, and I want to find the ones uses a specific functions, say "ImageDataGenerator".

Solution

C:\Windows\system32>d:
D:\>findstr "ImageDataGenerator" *.py

You can change the drive by simply input d:.
Use findstr "<TARGET STRING>" <PATH NAME> to find the scripts containing TARGET STRING.

That's it.
