BUSCTL(1) busctl 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 username and
hostname separated by "@", to connect to. This will use SSH to talk
to the remote machine manager instance.
-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.
