# Compare two directories
canon compare /path/to/folder_a /path/to/folder_b

# With filters
canon compare /path/to/folder_a /path/to/folder_b --where 'source.ext=jpg'

# Show file paths for differences
canon compare /path/to/folder_a /path/to/folder_b --verbose

  • Files only in A (by content)
  • Files only in B (by content)
  • Files in both (matching content hash)

Exit code is 0 if identical, 1 if differences found.
