Quick alternative:

  #!/bin/bash

  if [ "$#" -ne 2 ]; then
    echo "Usage: $0 <file-to-upload> <s3-bucket-name>"
    exit 1
  fi

  FILE_TO_UPLOAD=$1
  S3_BUCKET=$2
  S3_OBJECT_NAME=$(basename "$FILE_TO_UPLOAD")

  aws s3 cp "$FILE_TO_UPLOAD" "s3://$S3_BUCKET/$S3_OBJECT_NAME" --acl public-read

  if [ $? -eq 0 ]; then
    echo "File uploaded successfully."
    PUBLIC_URL="https://$S3_BUCKET.s3.amazonaws.com/$S3_OBJECT_NAME"
    echo "The file is publicly accessible at: $PUBLIC_URL"
  else
    echo "Failed to upload file."
    exit 1
  fi
