About:
chkbit is a command-line utility designed to proactively detect data corruption in your files. It generates and verifies checksums (like SHA-256) to identify bit rot, storage errors, or accidental modifications. This tool provides a simple yet powerful way to ensure the long-term integrity of your valuable data.
Key Features:
  • Generates and verifies checksums for files and directories
  • Detects silent data corruption (bit rot)
  • Fast and efficient, suitable for large datasets
  • Stores metadata in a local '.chkbit' database
Use Cases:
  • Verifying the integrity of backups and archives
  • Periodically checking for silent data corruption on NAS drives
  • Validating file transfers after moving large datasets
Alternatives:
  • hashdeep – More complex, supports a wider range of hash formats but with a steeper learning curve.
  • shasum -c – Requires pre-generated checksum files; lacks a dedicated database for ongoing management.
