Hi, The `diff` command in `diffutils` can compare the difference between two directories.
However, for large directories (the size for each file is small), when traversal through them, `diff` command will eat up all the system memory. My computer is 16GB RAM. And I believe this issue still exist for system with 32GB or 64GB RAM. I would suggest that it can use more memory efficient algorithm to compare the difference between directories. Regards!!!
