The problem statement doesn't appear to be very well specified. Are you trying to enforce that say rootdir2 is a subset of rootdir1? - assuming that file structure is the same underneath both rootdirs? diff will compare two single files together. So now the problem appears to be how to select the two files to compare against?

There are a number of recent posts about File::Find. Do a super search on that.
