Originally based on Alex Kudlick's [[https://github.com/akud/aws-s3-sync-by-hash][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
|
|
|
|
#+begin_example
|
|
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
|
|
-i, --include <value> Include matching paths
|
|
-x, --exclude <value> Exclude matching paths
|
|
-v, --verbose <value> Verbosity level (1-5)
|
|
#+end_example
|
|
|
|
The ~--include~ and ~--exclude~ parameters can be used more than once.
|
|
|
|
* 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/s3thorp-assembly-$VERSION.jar` (where $VERSION
|
|
is substituted)
|
|
|
|
Copy and rename this file as `s3thorp.jar` into the same directory as
|
|
the `bin/s3throp` shell script.
