s3thorp

Synchronisation of files with S3 using the hash of the file contents.

Originally based on Alex Kudlick's aws-s3-sync-by-hash.

The normal aws s3 sync ... command only uses the time stamp of files to decide what files need to be copied. This utility looks at the md5 hash of the file contents.

Usage 

  s3thorp
  Usage: s3thorp [options]

    -s, --source <value>   Source directory to sync to S3
    -b, --bucket <value>   S3 bucket name
    -p, --prefix <value>   Prefix within the S3 Bucket
    -v, --verbose <value>  Verbosity level (1-5)
