Simple File Upload to Amazon S3 From Ruby

There's more about Amazon S3 and Marcel Molina's hot new library coming as the first day of the Ruby Advent Calendar (this Friday!), so I don't want to say too much about it yet. For anyone already enjoying this library, however, I put together a scrappy program that lets me copy files up to S3 from the command line easily:

#!/usr/bin/env ruby

require 'rubygems'
require 'aws/s3'

local_file = ARGV[0]
bucket = ARGV[1]
mime_type = ARGV[2] || "application/octet-stream"

AWS::S3::Base.establish_connection!(
  :access_key_id     => 'REPLACE_ME',
  :secret_access_key => 'REPLACE_ME'
)

base_name = File.basename(local_file)

puts "Uploading #{local_file} as '#{base_name}' to '#{bucket}'"

AWS::S3::S3Object.store(
  base_name,
  File.open(local_file),
  bucket,
  :content_type => mime_type
)

puts "Uploaded!"

Just name it s3cp (or similar), chmod it, and then you can do stuff like:

s3cp ~/somefile.whatever bucket
