Is there a way to list all domains on an SAN/UCC SSL Certificate (ideally using command line on linux/os x)?

Clearly there must be some way to extract the data, since browsers can do it. Unfortunately, I can see the list but can't cut and paste it.

openssl x509 -text < foo.crt should do the trick.

For posterity, this is the full command I used, since I was doing it for another server: openssl s_client -showcerts -connect www.example.org:443 | openssl x509 -text –  Jordan Reiter Sep 10 '12 at 13:39
