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).

Command-line arguments

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
