NAME

       parallel-sums - Calculate checksums in parallel using multiple algorithms

SYNOPSIS

       parallel-sums --algo1 ALGO1FILE [--algo2 ALGO2FILE ... --algoN ALGONFILE] file1 [file2 ...
       fileN

       parallel-sums --help

DESCRIPTION

       parallel-sums is designed to make it faster and easier  to  create  checksum  files  using
       multiple  algorithms. It will only read the data from each input file once, spawning a new
       thread per checksum algorithm requested and running calculations in parallel.

       Specify the list of desired checksum algorithms along with the output  filename  for  each
       checksum type, then pass the list of files.

       The  output is intended to be 100% compatible with the file formats of existing tools like
       md5sum, sha256sum etc.

       --algo ALGOSUMS
              Checksum all input files using the algorithm "algo" and output the checksums in the
              file ALGOSUMS.

       --help Print usage information and list the checksum algorithms supported.

EXAMPLES

       parallel-sums --md5sum MD5SUMS --sha256sum SHA256SUMS *.iso
              Read  all  files  matching the pattern *.iso. In parallel, checksum each file using
              the MD5 algorithm (writing to "MD5SUMS") and checksum each file  using  the  SHA256
              algorithm (writing to "SHA256SUMS").
