I don't see a problem in the above. That df and du displays different information is an FAQ. Does this reference help you? https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#df-and-du-report-different-information That FAQ doesn't consider hardlinks. I suppose it should be updated to mention the difference there too. Bob
