#!/bin/bash -xev

# USAGE
#
#  This script provides 6 flags
#    --sandbox     : pushes to beta-hyper-sdk-assets bucket on S3
#    --no-compress : skips compression of images
#    --no-resize   : skips images resizing
#
#  Extra flags
#    --f      : for pushing without confirmation
#
#  ---- For pushing to production bucket
#       This defaults to s3://jp-remote-assets/hyper/...
#       $ bash -e push.sh <path to asset to be pushed>
#       eg: bash -e push.sh hyper/images/common/amazon_pay.png
#
#  ---- For pushing to sandbox bucket
#       This defaults to s3://beta-hyper-sdk-assets/hyper/...
#       $ bash -e push.sh <path to asset to be pushed> --sandbox
#       eg: bash -e push.sh hyper/images/common/amazon_pay.png
