Common operations

Listing my bitcoin addresses

Listing the bitcoin addresses in your wallet is easily done via listreceivedbyaddress. It normally lists only addresses which already have received transactions, however you can list all the addresses by setting the first argument to 0, and the second one to true.

Accounts are used to organize addresses.

getaccountaddress	<account>	Returns the current bitcoin address for receiving payments to this account.	N
getaddressesbyaccount	<account>	Returns the list of addresses for the given account.	N
getbalance	[account] [minconf=1]	If [account] is not specified, returns the server's total available balance. If [account] is specified, returns the balance in the account.	N
getblockcount		Returns the number of blocks in the longest block chain.	N
getblocknumber		Deprecated. Use getblockcount.	N
getconnectioncount		Returns the number of connections to other nodes.	N
getdifficulty		Returns the proof-of-work difficulty as a multiple of the minimum difficulty.	N
getgenerate		Returns true or false whether bitcoind is currently generating hashes	N
gethashespersec		Returns a recent hashes per second performance measurement while generating.	N
getinfo		Returns an object containing various state info.	N
getmemorypool	[data]	If [data] is not specified, returns data needed to construct a block to work on: "version" : block version "previousblockhash" : hash of current highest block "transactions" : contents of non-coinbase transactions that should be included in the next block "coinbasevalue" : maximum allowable input to coinbase transaction, including the generation award and transaction fees "time" : timestamp appropriate for next block "bits" : compressed target of next block If [data] is specified, tries to solve the block and returns true if it was successful.	N
getnewaddress	[account]	Returns a new bitcoin address for receiving payments. If [account] is specified (recommended), it is added to the address book so payments received with the address will be credited to [account].	N

N
help	[command]	List commands, or get help for a command.	N
keypoolrefill		Fills the keypool, requires wallet passphrase to be set.	Y

setaccount	<bitcoinaddress> <account>	Sets the account associated with the given address. Assigning address that is already assigned to the same account will create a new address associated with that account.	N
setgenerate	<generate> [genproclimit]	<generate> is true or false to turn generation on or off. Generation is limited to [genproclimit] processors, -1 is unlimited.	N
signmessage	<bitcoinaddress> <message>	Sign a message with the private key of an address.	Y
settxfee	<amount>	<amount> is a real and is rounded to the nearest 0.00000001	N
