NAME
dbus-monitor - debug probe to print message bus messages SYNOPSIS
dbus-monitor [--system | --session | --address ADDRESS] [--profile | --monitor] [watch expressions] DESCRIPTION
The dbus-monitor command is used to monitor messages going through a D-Bus message bus. See http://www.freedesktop.org/software/dbus/ for more information about the big picture. There are two well-known message buses: the systemwide message bus (installed on many systems as the "messagebus" service) and the per-user-login-session message bus (started each time a user logs in). The --system and --session options direct dbus-monitor to monitor the system or session buses respectively. If neither is specified, dbus-monitor monitors the session bus. dbus-monitor has two different output modes, the 'classic'-style monitoring mode and profiling mode. The profiling format is a compact for- mat with a single line per message and microsecond-resolution timing information. The --profile and --monitor options select the profiling and monitoring output format respectively. If neither is specified, dbus-monitor uses the monitoring output format. In order to get dbus-monitor to see the messages you are interested in, you should specify a set of watch expressions as you would expect to be passed to the dbus_bus_add_match function. The message bus configuration may keep dbus-monitor from seeing all messages, especially if you run the monitor as a non-root user. OPTIONS
--system Monitor the system message bus. --session Monitor the session message bus. (This is the default.) --address ADDRESS Monitor an arbitrary message bus given at ADDRESS. --profile Use the profiling output format. --monitor Use the monitoring output format. (This is the default.) EXAMPLE
Here is an example of using dbus-monitor to watch for the gnome typing monitor to say things dbus-monitor "type='signal',sender='org.gnome.TypingMonitor',interface='org.gnome.TypingMonitor'" AUTHOR
dbus-monitor was written by Philip Blundell. The profiling output mode was added by Olli Salli. BUGS

NAME
dbus-send - Send a message to a message bus SYNOPSIS
dbus-send [--system | --session] [--dest=NAME] [--print-reply] [--type=TYPE] <destination object path> <message name> [contents ...] DESCRIPTION
The dbus-send command is used to send a message to a D-Bus message bus. See http://www.freedesktop.org/software/dbus/ for more information about the big picture. There are two well-known message buses: the systemwide message bus (installed on many systems as the "messagebus" service) and the per- user-login-session message bus (started each time a user logs in). The --system and --session options direct dbus-send to send messages to the system or session buses respectively. If neither is specified, dbus-send sends to the session bus. Nearly all uses of dbus-send must provide the --dest argument which is the name of a connection on the bus to send the message to. If --dest is omitted, no destination is set. The object path and the name of the message to send must always be specified. Following arguments, if any, are the message contents (mes- sage arguments). These are given as type-specified values and may include containers (arrays, dicts, and variants) as described below. <contents> ::= <item> | <container> [ <item> | <container>...] <item> ::= <type>:<value> <container> ::= <array> | <dict> | <variant> <array> ::= array:<type>:<value>[,<value>...] <dict> ::= dict:<type>:<type>:<key>,<value>[,<key>,<value>...] <variant> ::= variant:<type>:<value> <type> ::= string | int16 | uint 16 | int32 | uint32 | int64 | uint64 | double | byte | boolean | objpath D-Bus supports more types than these, but dbus-send currently does not. Also, dbus-send does not permit empty containers or nested con- tainers (e.g. arrays of variants). Here is an example invocation: dbus-send --dest=org.freedesktop.ExampleName /org/freedesktop/sample/object/name org.freedesktop.ExampleInterface.ExampleMethod int32:47 string:'hello world' double:65.32 array:string:"1st item","next item","last item" dict:string:int32:"one",1,"two",2,"three",3 variant:int32:-8 objpath:/org/freedesktop/sample/object/name Note that the interface is separated from a method or signal name by a dot, though in the actual protocol the interface and the interface member are separate fields. OPTIONS
The following options are supported: --dest=NAME Specify the name of the connection to receive the message. --print-reply Block for a reply to the message sent, and print any reply received. --system Send to the system message bus. --session Send to the session message bus. (This is the default.) --type=TYPE Specify "method_call" or "signal" (defaults to "signal"). AUTHOR
