Automated forced rename to name(1).ext and if that already exists, the next one that isn't already used without having something abysmal like name(1)(1).ext, that's a big no.
Let me rephrase some of what I said before to be extra clear
I want whatever directory of choosing to copy all files recursively in all the folders in that directory into a new destination folder without copying the folders in the previous directory, without overwriting any files in the destination folder and that includes the files that's in the directory that has the same name and file extension.
Doesn't need to be in bash, use whatever programming language you like that can be executed in the terminal by putting it in a .bin or whatever and chmod +x and all that typical basic stuff that's on the end user to deal with.
