Check if RHEL certs have been updated

I have a sample .pem file placed in /etc/pki/ca-trust/source/anchors, and I have run update-ca-trust, but I'm not sure how I can check if the command actually worked. I tried to cat /etc/pki/tls/certs/ca-bundle.crt for the contents of my sample .pem but no luck.

How can I make sure that my certs have been updated?

To downvoters, could you please give suggestions as to what I can elaborate upon to improve my question?

EDIT

Checking /etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt has also not shown anything, so I will assume that my sample cert was not actually added.

Solution 1:

Run this command to see what certs are actually inside the CA bundle on the server.

openssl x509 -text -noout -in /etc/ssl/certs/ca-bundle.crt

You can also use the above command, but substitute the path to your added CA cert, to examine the CA certificate you added.
