Quick question on forging:
So i followed instructions at http://heatnodes.org/heatnodes.pdf to setup a node and got that working. For setting up forging I am getting stuck.

I enter in:
read -s KEY ; curl -k -s "http://localhost:7733/api/v1/mining/start/${KEY// /%20}?api_key=s" ; unset KEY
with s being API key, are you supposed to enter your secret words within this command or hit enter and then paste them and hit enter again?

Either way nothing happens, not output displayed, does not go back to command prompt and I eventually have to do ctrl+c.
