I had this running perfectly and the blockchain was synching and at about 80% completion. I came home from work to a power outage.
I keep seeing to run bitcoin-qt, it doesn't appear that I have that. In /src/ I have bitcoin-cli, bitcoind, and bitcoin-tx. Obviously d is daemon, and -tx isn't what I want either. So I try
bitcoin-cli -datadir=/pi/home/bitcoin/ error: too few parameters (need at least command)
