I have two folders.
A is an older version of B, having been copied at some point.
There may be changes in A but that are not in B.

I wanna find out if there are any, and what they are if they exist.

How do i do that, preferably using Linux standard utils

@4censord Every time I've done this I've just

```bash
cd dir1
find . -type f | xargs md5sum > ../a
cd dir2
find . -type f | xargs md5sum > ../b

diff a b
```

Probably not the best but works on most systems
