BUSCTL(1)

NAME
busctl - Introspect the bus

SYNOPSIS

busctl [OPTIONS...] [COMMAND] [NAME...]

DESCRIPTION

busctl may be used to introspect and monitor the D-Bus bus.

OPTIONS

The following options are understood:

--address=ADDRESS
    Connect to the bus specified by ADDRESS instead of using suitable defaults for either the system or user bus (see --system and --user options).

--show-machine
    When showing the list of endpoints, show a column containing the names of containers they belong to. See systemd-machined.service(8).

--unique
    When showing the list of endpoints, show only "unique" names (of the form ":number.number").

--acquired
    The opposite of --unique — only "well-known" names will be shown.

--activatable
    When showing the list of endpoints, show only endpoints which have actually not been activated yet, but may be started automatically if accessed.

--match=MATCH
    When showing messages being exchanged, show only the subset matching MATCH.

--no-legend
    Do not print the legend, i.e. the column headers and the footer.

--user
    Talk to the service manager of the calling user, rather than the service manager of the system.

--system
    Talk to the service manager of the system. This is the implied default.

-H, --host=
    Execute the operation remotely. Specify a hostname, or a username and hostname separated by "@", to connect to. The hostname may optionally be suffixed by a container name, separated by ":", which connects directly to a specific container on the specified host. This will use SSH to talk to the remote machine manager instance. Container names may be enumerated with machinectl -H HOST.

-M, --machine=
    Execute operation on a local container. Specify a container name to connect to.

-h, --help
    Print a short help text and exit.

--version
    Print a short version string and exit.

--no-pager
    Do not pipe output into a pager.

COMMANDS

The following commands are understood:

list
    Show endpoints attached to the bus. This is the default if no command is specified.

monitor [NAME...]
    Dump messages being exchanged. If NAME is specified, show messages to or from this endpoint. Otherwise, show all messages on the bus.

status NAME
    Show process information and credentials of a bus endpoint.

help
    Show command syntax help.
