DESCRIPTION
       gdbus is a simple tool for working with D-Bus objects.
COMMANDS
       introspect
           Prints out interfaces and property values for a remote object. For
           this to work, the owner of the object needs to implement the
           org.freedesktop.DBus.Introspectable interface. If the --xml option
           is used, the returned introspection XML is printed, otherwise a
           parsed pretty representation is printed. The --recurse option can
           be used to introspect children (and their children and so on) and
           the --only-properties option can be used to only print the
           interfaces with properties.
       monitor
           Monitors one or all objects owned by the owner of bus_name.
       call
           Invokes a method on a remote object. Each argument to pass to the
           method must be specified as a serialized GVariant except that
           strings do not need explicit quotes. The return values are printed
           out as serialized GVariant values.
       emit
           Emits a signal. Each argument to include in the signal must be
           specified as a serialized GVariant except that strings do not need
           explicit quotes.
       wait
           Waits until bus_name is owned by some process on the bus. If the
           --activate is specified, that bus name will be auto-started first.
           It may be the same as the bus name being waited for, or different.
       help
           Prints help and exit.
BASH COMPLETION
       gdbus ships with a bash completion script to complete commands,
       destinations, bus names, object paths and interface/method names.
EXAMPLES
         This shows how to introspect an object - note that the value of each
         property is displayed:
           $ gdbus introspect --system \
                   --dest org.freedesktop.NetworkManager \
                   --object-path /org/freedesktop/NetworkManager/Devices/0
           node /org/freedesktop/NetworkManager/Devices/0 {
             interface org.freedesktop.DBus.Introspectable {
               methods:
                 Introspect(out s data);
             };
             interface org.freedesktop.DBus.Properties {
               methods:
                 Get(in  s interface,
                     in  s propname,
                     out v value);
                 Set(in  s interface,
                     in  s propname,
                     in  v value);
                 GetAll(in  s interface,
                        out a{sv} props);
             };
             interface org.freedesktop.NetworkManager.Device.Wired {
               signals:
                 PropertiesChanged(a{sv} arg_0);
               properties:
                 readonly b Carrier = false;
                 readonly u Speed = 0;
                 readonly s HwAddress = '00:1D:72:88:BE:97';
             };
             interface org.freedesktop.NetworkManager.Device {
               methods:
                 Disconnect();
               signals:
                 StateChanged(u arg_0,
                              u arg_1,
                              u arg_2);
               properties:
                 readonly u DeviceType = 1;
                 readonly b Managed = true;
                 readwrite o Ip6Config = '/';
                 readwrite o Dhcp4Config = '/';
                 readwrite o Ip4Config = '/';
                 readonly u State = 2;
                 readwrite u Ip4Address = 0;
                 readonly u Capabilities = 3;
                 readonly s Driver = 'e1000e';
                 readwrite s Interface = 'eth0';
                 readonly s Udi = '/sys/devices/pci0000:00/0000:00:19.0/net/eth0';
             };
           };
       The --recurse and --only-properties options can be useful when wanting
       to inspect all objects owned by a particular process:
           $ gdbus introspect --system --dest org.freedesktop.UPower --object-path / --recurse  --only-properties
           node / {
             node /org {
               node /org/freedesktop {
                 node /org/freedesktop/UPower {
                   interface org.freedesktop.UPower {
                     properties:
                       readonly b IsDocked = true;
                       readonly b LidForceSleep = false;
                       readonly b LidIsPresent = false;
                       readonly b LidIsClosed = false;
                       readonly b OnLowBattery = false;
                       readonly b OnBattery = false;
                       readonly b CanHibernate = true;
                       readonly b CanSuspend = true;
                       readonly s DaemonVersion = '0.9.10';
                   };
                   node /org/freedesktop/UPower/Policy {
                   };
                   node /org/freedesktop/UPower/Wakeups {
                     interface org.freedesktop.UPower.Wakeups {
                       properties:
                         readonly b HasCapability = true;
                     };
                   };
                 };
               };
             };
           };
       In a similar fashion, the introspect command can be used to learn
       details about the Notify method:
           [...]
             interface org.freedesktop.Notifications {
               methods:
                 GetServerInformation(out s return_name,
                                      out s return_vendor,
                                      out s return_version,
                                      out s return_spec_version);
                 GetCapabilities(out as return_caps);
                 CloseNotification(in  u id);
                 Notify(in  s app_name,
                        in  u id,
                        in  s icon,
                        in  s summary,
                        in  s body,
                        in  as actions,
                        in  a{sv} hints,
                        in  i timeout,
                        out u return_id);
             };
           [...]
       With this information, it's easy to use the call command to display a
       notification
           $ gdbus call --session \
                        --dest org.freedesktop.Notifications \
                        --object-path /org/freedesktop/Notifications \
                        --method org.freedesktop.Notifications.Notify \
                        my_app_name \
                        42 \
                        gtk-dialog-info \
                        "The Summary" \
                        "Here's the body of the notification" \
                        [] \
                        {} \
                        5000
           (uint32 12,)
       Monitoring all objects on a service:
           $ gdbus monitor --system --dest org.freedesktop.ConsoleKit
           Monitoring signals from all objects owned by org.freedesktop.ConsoleKit
           The name org.freedesktop.ConsoleKit is owned by :1.15
           /org/freedesktop/ConsoleKit/Session2: org.freedesktop.ConsoleKit.Session.ActiveChanged (false,)
           /org/freedesktop/ConsoleKit/Seat1: org.freedesktop.ConsoleKit.Seat.ActiveSessionChanged ('',)
           /org/freedesktop/ConsoleKit/Session2: org.freedesktop.ConsoleKit.Session.ActiveChanged (true,)
           /org/freedesktop/ConsoleKit/Seat1: org.freedesktop.ConsoleKit.Seat.ActiveSessionChanged ('/org/freedesktop/ConsoleKit/Session2',)
       Monitoring a single object on a service:
           $ gdbus monitor --system --dest org.freedesktop.NetworkManager --object-path /org/freedesktop/NetworkManager/AccessPoint/4141
           Monitoring signals on object /org/freedesktop/NetworkManager/AccessPoint/4141 owned by org.freedesktop.NetworkManager
           The name org.freedesktop.NetworkManager is owned by :1.5
           /org/freedesktop/NetworkManager/AccessPoint/4141: org.freedesktop.NetworkManager.AccessPoint.PropertiesChanged ({'Strength': <byte 0x5c>},)
           /org/freedesktop/NetworkManager/AccessPoint/4141: org.freedesktop.NetworkManager.AccessPoint.PropertiesChanged ({'Strength': <byte 0x64>},)
           /org/freedesktop/NetworkManager/AccessPoint/4141: org.freedesktop.NetworkManager.AccessPoint.PropertiesChanged ({'Strength': <byte 0x5e>},)
           /org/freedesktop/NetworkManager/AccessPoint/4141: org.freedesktop.NetworkManager.AccessPoint.PropertiesChanged ({'Strength': <byte 0x64>},)
       Emitting a signal:
           $ gdbus emit --session --object-path /foo --signal org.bar.Foo "['foo', 'bar', 'baz']"
       Emitting a signal to a specific process:
           $ gdbus emit --session --object-path /bar --signal org.bar.Bar someString --dest :1.42
       Waiting for a well-known name to be owned on the bus; this will not
       auto-start the service:
           $ gdbus wait --session org.bar.SomeName
       Auto-starting then waiting for a well-known name to be owned on the
       bus:
           $ gdbus wait --session --activate org.bar.SomeName
       Auto-starting a different service, then waiting for a well-known name
       to be owned on the bus. This is useful in situations where SomeName is
       not directly activatable:
           $ gdbus wait --session --activate org.bar.PrerequisiteName org.bar.SomeName
       Waiting for a well-known name and giving up after 30 seconds. By
       default, the timeout is disabled; or set --timeout to 0 to disable it:
           $ gdbus wait --session --timeout 30 org.bar.SomeName
