The basic command line arguments ( bettercap -h ) are:

argument description
-autostart MODULES Comma separated list of modules to auto start. (default to events.stream, net.recon)
-caplet FILENAME Read commands from this file and execute them in the interactive session.
-eval COMMANDS Run one or more commands separated by ; in the interactive session, used to set variables via command line.
-iface INTERFACE Network interface to bind to, if empty the default interface will be auto selected (accepts interface name, ip or mac address).
-gateway-override ADDRESS Use the provided IP address instead of the default gateway. If not specified or invalid, the default gateway will be used.
-no-history Disable the interactive session history file ~/.bettercap.history.
-no-colors Disable output color effects.
-env-file FILENAME Load environment variables from this file if found, set to empty to disable environment persistance. (default ~/bettercap.env)
-cpu-profile FILENAME Write cpu profile file (used for debugging and benchmarking).
-mem-profile FILENAME Write memory profile to file (used for debugging and benchmarking).
-silent Suppress all logs which are not errors.
-debug Enable debug messages.

If no -caplet option is specified, bettercap will start in interactive mode, allowing you to start and stop modules manually, change options and apply new firewall rules on the fly.

To get a grasp of what you can do, type help and the general help menu will be shown, you can also have module specific help by using help module-name (for instance try with help net.recon), to see which modules are running and their configuration at any time, you can use the active command.

To print all variables and their values instead, you can use get * or get variable-name to get a single variable (try with get gateway.address), to set a new value you can simply set variable-name new-value (a value of "" will clear the variable contents), on a typical session variables look like this.
