right...that's what I get for not trying it out for rea....
What I actually do is more like this:
(cd src/path; find . -type f -exec md5sum {} \; ) > src.md5sum
(cd dest/path; find . -type f -exec md5sum {} \; ) > dest.md5sum
diff src.md5sum dest.md5sum
But I also usually do it the first (wrong) way first, before remembering
this detail!
Cheers,
Bill
