I want to list the contents of this structure, but I want to exclude everything, in all directories, except the stuff in the root. In this case, that would be file1.txt and file2.txt. I know I can use --exclude, but if I have lots of subdirectories, I would need many --exclude calls, unless there's a way to exclude everything at once.
After running whatever command it is, I expect to see only file1.txt and file2.txt because they're the only things in /
