I need to be able to alphabetically sort the output of find before piping it to a command. Entering | sort | between didn't work, so what could I do?

find folder1 folder2 -name "*.txt" -print0 | xargs -0 myCommand



Question: How can I get my SSL certificate signed by an CA for web application that runs on localhost
Answer: You can't and you absolutely SHOULD NOT!

The main feature of X509 certificate signature in SSL/TLS is that a third party guarantees that you're actually connecting to a system that has been approved by the owner of a domain name (it is the assumption that you already know the relation between the domain name and the actual entity you're trying to interact with).

Issuing a certificate for a name that isn't uniquely linked to an entity does not allow that validation to take place: such a signed certificate wouldn't carry any guarantee.

The bright point, however, is that if the only way you're using SSL is to validate the server identity, then it simply it doesn't matter if the certificate is signed by a trusted CA: you should be using certificate pinning in any case (not that it matters much, mind you, since you can assume that if someone can hijack your service listening on the loopback address, he can also grab the private key associated with the certificate).
