How to process only modified files in a folder without using inotifywait in Linux shell script?
So I have a large number of files and folders inside a main folder.
Every time a file is edited in the main folder I want to GPG encrypt the file to prepare it for upload.
But I don't want to use inotifywait. I'd rather use something like diff but not sure what the right tool is and how to use it in a Shell script.
