mbo/digest: --check mode for the digest CLI#233
Merged
Conversation
-c/--check verifies checksum files: OK/FAILED per listed file, coreutils-style warnings and exit codes; accepts '*' binary markers and uppercase hex, so sum files are interchangeable with sha256sum/shasum in both directions (verified live). Companions: --quiet, --status, --ignore_missing (fails if nothing was verified), --strict (malformed lines fail). bashtest covers roundtrip, stdin, coreutils format, corruption, quiet/status, missing/ignore-missing, and strict.

Implements the verification half of the checksum workflow (the unscheduled idea from TODO):
-c/--check: arguments become checksum files (-= stdin); every listed file is re-digested with the selected-aalgorithm and reportedOK/FAILED/FAILED open or read, with coreutils-style stderr warnings and exit codes.shasum -a 256output checks clean underdigest -c, anddigestoutput checks clean undershasum -c -. Accepts*binary markers and uppercase hex.--quiet(no OK lines),--status(exit code only),--ignore_missing(skip unreadable listed files; still fails if no file was verified),--strict(improperly formatted lines fail).-a- hash length cannot disambiguate (32 bytes could be sha256, sha3-256, blake2b-256, or blake3).
