Introduction to D-BUS

D-BUS is a message bus system, a simple way for applications to talk to one another. D-BUS supplies both a system daemon (for events such as “new hardware device added” or “printer queue changed”) and a per-user-login-session daemon (for general IPC needs among user applications). Also, the message bus is built on top of a general one-to-one message passing framework, which can be used by any two applications to communicate directly (without going through the message bus daemon).

Contents

Installed Programs:	dbus-daemon, dbus-send, dbus-monitor, dbus-launch, dbus-cleanup-sockets, dbus-uuidgen

Installed Directories:	/usr/lib/dbus-1.0/include/dbus, /etc/dbus-1, /var/run/dbus, /etc/dbus-1/system.d, /usr/share/dbus-1/services, and /usr/share/doc/dbus-1.8.0

Short Descriptions

dbus-cleanup-sockets	is used to clean up leftover sockets in a directory.
dbus-daemon	is the D-BUS message bus daemon.
dbus-launch	is used to start dbus-daemon from a shell script. It would normally be called from a user's login scripts.
dbus-monitor	is used to monitor messages going through a D-BUS message bus.
dbus-send	is used to send a message to a D-BUS message bus.
dbus-viewer	is a graphical D-BUS frontend utility.
libdbus-1.{so,a}	contains the API functions used by the D-BUS message daemon. D-BUS is first a library that provides one-to-one communication between any two applications; dbus-daemon is an application that uses this library to implement a message bus daemon.
