thorp

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

  thorp
  Usage: thorp [options]

    -s, --source <value>  Source directory to sync to S3
    -b, --bucket <value>  S3 bucket name
    -p, --prefix <value>  Prefix within the S3 Bucket
    -i, --include <value> Include matching paths
    -x, --exclude <value> Exclude matching paths
    -d, --debug           Enable debug logging
    --no-global           Ignore global configuration
    --no-user             Ignore user configuration

If you don't provide a source the current diretory will be used.

The --include and --exclude parameters can be used more than once.

Configuration

Configuration will be read from these files:

• Global: /etc/thorp.conf
• User: ~ /.config/thorp.conf
• Source: ${source}/.thorp.conf

Command line arguments override those in Source, which override those in User, which override those Global, which override any built-in config.

Built-in config consists of using the current working directory as the source.

Note, that include and exclude are cumulative across all configuration files.

Behaviour

When considering a local file, the following table governs what should happen:

#	local file	remote key	hash of same key	hash of other keys	action
1	exists	exists	matches	-	do nothing
2	exists	is missing	-	matches	copy from other key
3	exists	is missing	-	no matches	upload
4	exists	exists	no match	matches	copy from other key
5	exists	exists	no match	no matches	upload
6	is missing	exists	-	-	delete

Executable JAR

To build as an executable jar, perform `sbt assembly`

This will create the file `cli/target/scala-2.12/thorp`

Copy this file to your `PATH`.
