Command line tools shouldn't be vulnerable to POODLE.
The reason is that POODLE is a cross-domain attack where the attacker can send cross-origin requests to the vulnerable endpoint and then use their Man-in-the-Middle/eavesdropper position to read cookie data sent with the request.
the browser to make requests (with cookies) to any other origin. If
the attacker does this block duplication trick they have a 1-in-256
chance that the receiver won't reject the record and close the
connection. If the receiver accepts the record then the attacker knows
that the decryption of the cookie block that they duplicated, XORed
with the ciphertext of the previous block, equals seven. Thus they've
found the last byte of the cookie using (on average) 256 requests.
That said, there are other vulnerabilities present in SSLv3 that mean an upgrade is recommended.
Running an SSLv3 server is the best way to test it, as Ángel points out.
