Software for text search in files
I have a python project with nested folder structure
src/ folder_1 folder_2 subfolder_1 subfolder_2 folder_3 subfolder_1 subsubfolder_1 subfolder_2 etc.
I am looking for a piece of code and the project is too big to go through every file manually.
Is there a way to search for a string "mystring" inside all the files located in src or any subfolder of src?
