parallel-sums1
Calculate checksums in parallel using multiple algorithms
Usage
parallel-sums --help
Overview
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").
