Question

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

Answer 1

In the newer version of AWS CLI, you can use the following code to detect the existence of a file or directory

count=$(aws s3 ls $path | wc -l)
if [ $count -gt 0 ]
then
  (>&2 echo "$path already exists!")
  return
fi
