asked on

what to see what cpio would do without writing

I have two similar directories and I want to compare them to see what would be copied.

Normall I would cd to a dir and then just run the command:

find . -print | cpio -pdvm /foo/bar

but I cannot recall and worse find in the man to set cpio to read-only -- meaning just show me what it would have done. My memory tells me that I used to be able to do this. But I might have dreamt it since I cannot recall the last time I actually used that option.

The OS today is OS X 10.8.2

Sorry for long delay -- holidays got in the way

both the diff and rsync would have worked -- but the rsync is more of what I was looking for

must have dreamt the cpio part
