Simple shell script that uses curl to send a file to s3. Useful when you do not want to load the awscli for a simple job. May have to adjust mime types according to need.

send2s3.sh

#!/bin/sh

if [ $# -ne 1 ] ; then
  echo "Need File Name"
  exit
fi

s3AccessKey="##ACCESS##"
s3SecretKey="##SECRET##"
s3Bucket="data.example.com"

#Strips path from file so it is not created on S3
DIR=`dirname $1`
FILE=`basename $1`
cd $DIR
fileName=$FILE

EXT=`basename $1 | awk -F"." '{print $NF}'`

case $EXT in
