is there any working example of how to use verify_hostname in command line?

Hi,

I am having a very  hard time to get the command line working. Basically just trying to verify hostname via opoenssl command line:

openssl s_client  -CApath . -CAfile ./cacert.pem -verify_hostname example.com

All I get is "unknown option -verify_hostname

usage: s_client args"

Have tried combinations of that and check out of doc... really not helping.

Openssl using:

openssl version
LibreSSL 2.8.3
