Bash script to upload files and directories to S3

upload-s3.sh

#!/bin/bash

# S3 server
server=""

# set the path based on the first argument
path=$1

# remove the last slash from the directory, if necessary
if [[ "$path" =~ '/'$ ]]; then
  path=${path%?}
fi

# name of the S3 bucket
bucket_name=""

# credentials
secret=""
s3_key=""

function uploadFile
{
  path=$1

  # get the current date to calculate the signature
  date=`date +'%a, %d %b %Y %H:%M:%S %z'`

  # calculate the signature to be sent as a header
  content_type="application/octet-stream"
  string_to_sign="PUT\n\n$content_type\n${date}\n/${bucket_name}/${path}"
  signature=$(echo -en "${string_to_sign}" | openssl sha1 -hmac "${secret}" -binary | base64)

  # upload file
  echo "uploading ${path}"
  curl -X PUT -T "${path}" \
       -H "Host: ${server}/${bucket_name}" \
       -H "Date: $date" \
       -H "Content-Type: $content_type" \
       -H "Authorization: AWS ${s3_key}:${signature}" \
       "https://${server}/${bucket_name}/${path}"
}

# loop through the path and upload the files
find $path -type f -print0 | while read -d $'\0' file; do
  uploadFile "$file"
done

Now aws cant support sha1.
