Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

What others think

This info is available in the much more intuitive (to me at least):

curl -k https://www.google.com -v

If you just want certificate details then:

curl -k -I https://www.google.com -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.

Comment by wam 329 weeks ago

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
