Today sees a new release of Cliaws. This is a simple library to interact with S3 (and other services) through the command-line. This library is very similar to Amazon’s own ec2-* scripts, except this library is written in Ruby.

Interacting with S3 should be no harder than:

1 $ clis3 put my-local-file my-bucket/my-s3-file

Put many files at once:

1 $ clis3 put my-local-file0 my-local-file1 my-bucket/my-s3-directory/

Put an environment variable:

1 $ clis3 put --data $MY_DATA my-bucket/my-env-value

Put stdin too!

1 $ tar czfv /var/cache/mylvmbackup/backup | clis3 put - my-bucket/my-backup/backup-20080825-000000.tar.gz

All of this functionnality is available from with Ruby too:

1 require "rubygems"
2 require "cliaws"
4 Cliaws.s3.put("this is the content", "my-bucket/my-s3-file")
5"my-local-file", "rb") do |io|
6   Cliaws.s3.put(io, "my-bucket/my-s3-file")
7 end

Give the RubyForge gem servers a couple of hours to refresh themselves, and then enjoy!
