How to get the id of the root process group in nifi 1.1.2 using curl?

Nevermind, I was able to discover it.

export PYTHONIOENCODING=utf8; curl -s -k --cert <cert file> https://127.0.0.1:9443/nifi-api/flow/process-groups/root | python -c "import sys, json; print json.load(sys.stdin) ['processGroupFlow']['id']"
