A git command line tool that verifies the connectivity and validity of the objects in the database

git-fsck tests SHA-1 and general object sanity, and it does full tracking of the resulting reachability and everything else. It prints out any corruption it finds (missing or bad objects), and if you use the --unreachable flag it will also print out objects that exist but that aren't reachable from any of the specified head nodes (or the default set, as mentioned above).
