There are two variations of the official bitcoin program available; one with a graphical user interface (usually referred to as just “Bitcoin”), and a 'headless' version (called bitcoind). They are completely compatible with each other, and take the same command-line arguments, read the same configuration file, and read and write the same data files. You can run one copy of either Bitcoin or bitcoind on your system at a time (if you accidently try to launch another, the copy will let you know that Bitcoin or bitcoind is already running and will exit).
Give Bitcoin (or bitcoind) the -? or –help argument and it will print out a list of the most commonly used command-line arguments and then exit:
bitcoin [options] bitcoin [options] <command> [params] Send command to -server or bitcoind bitcoin [options] help List commands bitcoin [options] help <command> Get help for a command
-conf=<file> Specify configuration file (default: bitcoin.conf) -gen Generate coins -gen=0 Don't generate coins -min Start minimized -datadir=<dir> Specify data directory -proxy=<ip:port> Connect through socks4 proxy -addnode=<ip> Add a node to connect to -connect=<ip> Connect only to the specified node -server Accept command line and JSON-RPC commands -daemon Run in the background as a daemon and accept commands -? This help message
Bitcoin.conf Configuration File
All command-line options (except for -datadir and -conf) may be specified in a configuration file, and all configuration file options may also be specified on the command line. Command-line options override values set in the configuration file.
The configuration file is a list of setting=value pairs, one per line, with optional comments starting with the '#' character.
The configuration file is not automatically created; you can create it using your favorite plain-text editor. By default, Bitcoin (or bitcoind) will look for a file named 'bitcoin.conf' in the bitcoin data directory, but both the data directory and the configuration file path may be changed using the -datadir and -conf command-line arguments.
|Operating System||Default bitcoin datadir||Typical path to configuration file|
|Windows||%APPDATA%\Bitcoin\||:\Documents and Settings\username\Application Data\Bitcoin\bitcoin.conf|
|Mac OSX||$HOME/Library/Application Support/Bitcoin/||/Users/username/Library/Application Support/Bitcoin/bitcoin.conf|
Here is a sample bitcoin.conf file, containing every option set to its default value.
