Upload files to S3 with a few lines of Bash

upload-s3.sh

# You don't need Fog in Ruby or some other library to upload to S3 -- shell works perfectly fine
# This is how I upload my new Sol Trader builds (http://soltrader.net)
# Based on a modified script from here: http://tmont.com/blargh/2014/1/uploading-to-s3-in-bash

# export S3KEY="my aws key"
# export S3SECRET="my aws secret" # pass these in

BUCKET="apps-crawler-prod"

  datetime=$(date +"%a, %d %b %Y %T %z")
  echo "uploading $file to s3:$BUCKET$aws_path ($datetime)"
  acl="x-amz-acl:public-read"
  content_type='application/x-compressed-tar'
