rotsniff is a tool to catalog files and their hashes in order to detect corrupted or missing files.
It was inspired by scorch, and the database format is similar, but do not expect any kind of compatibility at this time.
Usage: rotsniff [OPTIONS] <COMMAND>
Commands:
append Add files not found in the database
remove Remove entries from the database that no longer exists
update Update entries in the database for files that have changed
verify Verify that all files in the database are intact, and that all files have entries in the database
help Print this message or the help of the given subcommand(s)
Options:
--db <FILE> Path to the database file [default: ./rotsniff.db]
-v, --verbose Make `command` more verbose. Actual behavior depends on the command
-f, --fnfilter <FNFILTER> Restrict commands to files which match regex
-F, --negate-fnfilter Negate the fnfilter regex match
-h, --help Print help
-V, --version Print version
You can install the latest tagged version directly from crates.io by running the following command.
cargo install rotsniff
% mkdir foo
% echo 'Hello, World!' > foo/hello
% rotsniff -v append foo
foo/hello: blake2b:94D8520FE182ADD62BEC85B531A17A779FCD39F23248CFABD18347B86CE9F8B73A0C151DD7CE171843DD8A14E5329DDE6B73149D26D6638E94EF4C634F3F1A7B
% rotsniff -v verify foo
MATCH: foo/hello
% echo 'Goodbye!' > foo/hello
% rotsniff -v verify foo
MODIFIED: foo/hello
% rotsniff -v update
UPDATED: foo/hello
% rm foo/hello
% touch foo/new
% rotsniff -v verify foo
FILE NOT FOUND: foo/hello
NOT FOUND IN DB: foo/new
% rotsniff -v append foo
foo/new: blake2b:786A02F742015903C6C6FD852552D272912F4740E15847618A86E217F71F5419D25E1031AFEE585313896444934EB04B903A685B1448B755D56F701AFE9BE2CE

The database is a simple CSV text file that is compressed with gzip, in order to be future proof and easily parsed by other software if required.
% rotsniff -v append foo
foo/test: blake2b:7DFDB888AF71EAE0E6A6B751E8E3413D767EF4FA52A7993DAA9EF097F7AA3D949199C113CAA37C94F80CF3B22F7D9D6E4F5DEF4FF927830CFFE4857C34BE3D89
% zcat < rotsniff.db
foo/test,blake2b:7DFDB888AF71EAE0E6A6B751E8E3413D767EF4FA52A7993DAA9EF097F7AA3D949199C113CAA37C94F80CF3B22F7D9D6E4F5DEF4FF927830CFFE4857C34BE3D89
The format is currently file,hash:digest, but this may change to include more data in the future. The only supported
hash function for now is BLAKE2b.
