xxh32sum 0.8.4 by Yann Collet
Create or verify checksums using fast non-cryptographic algorithm xxHash

Usage: xxh32sum [options] [files]

When no filename provided or when '-' is provided, uses stdin as input.

Options:
  -H#                  select an xxhash algorithm (default: 0)
                       0: XXH32
                       1: XXH64
                       2: XXH128 (also called XXH3_128bits)
                       3: XXH3   (also called XXH3_64bits)
  -c, --check          read xxHash checksum from [files] and check them
      --files-from     generate hashes for files listed in [files]
      --filelist       generate hashes for files listed in [files]
  -                    forces stdin as input, even if it's the console
  -h, --help           display a long help page about advanced options

Advanced:
  -V, --version        Display version information
      --tag            Produce BSD-style checksum lines
      --little-endian  Checksum values use little endian convention (default: big endian)
      --binary         Read in binary mode
  -s#, --seed #        Set seed (default: 0)
  -b                   Run benchmark
  -b#                  Bench only algorithm variant #
  -i#                  Number of times to run the benchmark (default: 3)
  -B#                  Block size to hash per benchmark iteration (default: 102400 B)
  -q, --quiet          Don't display version header in benchmark mode

The following five options are useful only when using lists in [files] to verify or generate checksums:
  -q, --quiet          Don't print OK for each successfully verified hash
      --status         Don't output anything, status code shows success
      --strict         Exit non-zero for improperly formatted lines in [files]
      --warn           Warn about improperly formatted lines in [files]
      --ignore-missing Don't fail or report status for missing files
