22 gdbus offers a simple commandline utility for introspecting and calling
23 methods on remote objects.
24 Commands
26 introspect
27 Prints out interfaces and property values for a remote object. For
28 this to work, the owner of the object needs to implement the
29 org.freedesktop.DBus.Introspectable interface.
30 monitor
32 Monitors one or all objects owned by the owner of bus_name.
33 call
35 Invokes a method on a remote object. Each argument to pass to the
36 method must be specified as a serialized GVariant except that
37 strings do not need explicit quotes. The return values are printed
38 out as serialized GVariant values.
39 help
41 Prints help and exit.
42
44 gdbus ships with a bash completion script to complete commands,
45 destinations, bus names, object paths and interface/method names.
46
48 This shows how to introspect an object - note that the value of each
49 property is displayed:
50 $ gdbus introspect --system \
52 --dest org.freedesktop.NetworkManager \
53 --object-path /org/freedesktop/NetworkManager/Devices/0
54 node /org/freedesktop/NetworkManager/Devices/0 {
55 interface org.freedesktop.DBus.Introspectable {
56 methods:
57 Introspect(out s data);
58 };
59 interface org.freedesktop.DBus.Properties {
60 methods:
61 Get(in s interface,
62 in s propname,
63 out v value);
64 Set(in s interface,
65 in s propname,
66 in v value);
67 GetAll(in s interface,
68 out a{sv} props);
69 };
70 interface org.freedesktop.NetworkManager.Device.Wired {
71 signals:
72 PropertiesChanged(a{sv} arg_0);
73 properties:
74 readonly b Carrier = false;
75 readonly u Speed = 0;
76 readonly s HwAddress = ´00:1D:72:88:BE:97´;
77 };
78 interface org.freedesktop.NetworkManager.Device {
79 methods:
80 Disconnect();
81 signals:
82 StateChanged(u arg_0,
83 u arg_1,
84 u arg_2);
85 properties:
86 readonly u DeviceType = 1;
87 readonly b Managed = true;
88 readwrite o Ip6Config = ´/´;
89 readwrite o Dhcp4Config = ´/´;
90 readwrite o Ip4Config = ´/´;
91 readonly u State = 2;
92 readwrite u Ip4Address = 0;
93 readonly u Capabilities = 3;
94 readonly s Driver = ´e1000e´;
95 readwrite s Interface = ´eth0´;
96 readonly s Udi = ´/sys/devices/pci0000:00/0000:00:19.0/net/eth0´;
97 };
98 };
99 In a similar fashion, the introspect command can be used to learn
101 details about the Notify method:
102 [...]
104 interface org.freedesktop.Notifications {
105 methods:
106 GetServerInformation(out s return_name,
107 out s return_vendor,
108 out s return_version,
109 out s return_spec_version);
110 GetCapabilities(out as return_caps);
111 CloseNotification(in u id);
112 Notify(in s app_name,
113 in u id,
114 in s icon,
115 in s summary,
116 in s body,
117 in as actions,
118 in a{sv} hints,
119 in i timeout,
120 out u return_id);
121 };
122 [...]
123 With this information, it´s easy to use the call command to display a
125 notification
126 $ gdbus call --session \
128 --dest org.freedesktop.Notifications \
129 --object-path /org/freedesktop/Notifications \
130 --method org.freedesktop.Notifications.Notify \
131 my_app_name \
132 42 \
133 gtk-dialog-info \
134 "The Summary" \
135 "Here´s the body of the notification" \
136 [] \
137 {} \
138 5000
139 (uint32 12,)
140 Monitoring all objects on a service:
142 $ gdbus monitor --system --dest org.freedesktop.ConsoleKit
144 Monitoring signals from all objects owned by org.freedesktop.ConsoleKit
145 The name org.freedesktop.ConsoleKit is owned by :1.15
146 /org/freedesktop/ConsoleKit/Session2: org.freedesktop.ConsoleKit.Session.ActiveChanged (false,)
147 /org/freedesktop/ConsoleKit/Seat1: org.freedesktop.ConsoleKit.Seat.ActiveSessionChanged (´´,)
148 /org/freedesktop/ConsoleKit/Session2: org.freedesktop.ConsoleKit.Session.ActiveChanged (true,)
149 /org/freedesktop/ConsoleKit/Seat1: org.freedesktop.ConsoleKit.Seat.ActiveSessionChanged (´/org/freedesktop/ConsoleKit/Session2´,)
150 Monitoring a single object on a service:
152 $ gdbus monitor --system --dest org.freedesktop.NetworkManager --object-path /org/freedesktop/NetworkManager/AccessPoint/4141
154 Monitoring signals on object /org/freedesktop/NetworkManager/AccessPoint/4141 owned by org.freedesktop.NetworkManager
155 The name org.freedesktop.NetworkManager is owned by :1.5
156 /org/freedesktop/NetworkManager/AccessPoint/4141: org.freedesktop.NetworkManager.AccessPoint.PropertiesChanged ({´Strength´: <byte 0x5c>},)
157 /org/freedesktop/NetworkManager/AccessPoint/4141: org.freedesktop.NetworkManager.AccessPoint.PropertiesChanged ({´Strength´: <byte 0x64>},)
158 /org/freedesktop/NetworkManager/AccessPoint/4141: org.freedesktop.NetworkManager.AccessPoint.PropertiesChanged ({´Strength´: <byte 0x5e>},)
159 /org/freedesktop/NetworkManager/AccessPoint/4141: org.freedesktop.NetworkManager.AccessPoint.PropertiesChanged ({´Strength´: <byte 0x64>},)
