I have created my wallet and have monero running in background, though I am not entirely sure how to tell. I just know that I try to run ./monerod I receive an error message stating that "Address already in use". Sine I am new to this I am worried that my wallet is not attached to my address. If it is not, am I even accomplishing anything by running ./monerod? I am sorry to keep posting but I had never used Linux until yesterday so large learning curve. Thanks in advance for any help!
I'll take a guess you are trying to run more than one monerod instance at a time. You can do this if you assign them different ports, otherwise you'll get that address already in use error. You only need one monerod instance running at a time.
With monerod running, open monero-wallet-cli. It will ask you for your wallet file location and the password. Once provided type the command
address and it will display the address associated with that wallet.
