Close, but not quite. what I really want is:
614 $ cat h
#! /bin/sh -x

curl --head \
     --remote-name \
     --remote-header-name \
     --write-out '%{filename_effective}\n' \
  'https://ibm-docs-static-content.s3.us.cloud-object-storage.appdomain.cloud/pdx/SSLTBW_3.1.0/zOS310-Refresh-Indexed-PDF-package-(2024-07-31).zip'

But it fails with:
615 $ sh h
curl: showing headers and --remote-header-name cannot be combined
curl: try 'curl --help' or 'curl --manual' for more information
616 $
