How to apply content type to Amazon S3 objects

Question

Using CLI (not s3cmd) to manage Amazon S3, how can I select all objects with extension .pdf and apply the content type application/pdf?

This is what I came up with so far:

aws s3 sync s3://${BUCKET_NAME} s3://${BUCKET_NAME}
--dryrun
--exclude '*'
--include '*.pdf'
--no-guess-mime-type
--content-type application/pdf

Using the --debug parameter I found out about this error:

An error occurred (InvalidRequest) when calling the CopyObject operation:
This copy request is illegal because it is trying to copy an object to itself
without changing the object's metadata, storage class,
website redirect location or encryption attributes.

Can you try your command with no option. Then add option one by one to see when it fails ? — Sylwit, Dec 13 '16 at 06:09
@Sylwit I used the --debug parameter, found the error and updated the question. — bart, Dec 13 '16 at 06:36

Try changing metadata directly:

aws s3 sync s3://${BUCKET_NAME} s3://${BUCKET_NAME}
--dryrun
--exclude '*'
--include '*.pdf'
--no-guess-mime-type
--metadata Content-Type=application/pdf
