What Others Think

This info is available in the much more intuitive (to me at least): curl -k -v If you just want certificate details then: curl -k -I -v 2>&1 | sed -ne '/Server certificate:/,/* SSL/ p' is still shorter

bleh, the URL conversion used on this site is inaccurate. That should just be a URL in those commandlines I commented on above, not the mess of 'a href' linkage.

I agree with wam, what he is recommending is more intuitive. I use the following based on wams suggestion. curl -vs $URL 2>&1 | grep [d]ate
