I have been mining to the address I created on my mining Linux box with geth. I can list my accounts with geth account list but how do I check my balance. My mining pool has made one payout to my address since I've started mining so I should have .02 eth there but I'd like to see it to be sure and to know that I have access to send to and from it. Secondly I'm not sure if I even remember my password or not and I don't know where or how to enter my password to verify if I remember it or not. How can I check my password with geth? Thanks.
