title: Checking if a file is in a S3 bucket using the s3cmd
body: <p>I having a program that successfully uploads all of the files that I need. I have new files everyday that I need to upload. After I have uploaded the files I no longer need them and thus am not looking to sync them. </p>
  
  <p>I am curious if there is a way to check if given a path and file name if that exists within S3 using the s3cmd.</p>
