| Command-line Options | A list of commands for Geth |
Geth is primarily controlled using the command line. Geth is started using the geth
command. It is stopped by pressing ctrl-c.
You can configure Geth using command-line options (a.k.a. flags). Geth also has sub-commands, which can be used to invoke functionality such as the console or blockchain import/export.
The command-line help listing is reproduced below for your convenience. The same information can be obtained at any time from your own Geth instance by running:
geth --help
