--- title: Command-line Options sort_key: A --- Geth is primarily controlled using the command line. Geth is started using the `geth` command. Geth is stopped by pressing `ctrl-c`. There are then many combinations of commands that configure precisely how geth will run. These commands are displayed below. The same information can be obtained at any time from your Geth instance by running ```sh geth --help ``` ## Commands ``` NAME: geth - the go-ethereum command line interface Copyright 2013-2022 The
