.SH NAME
dbus-launch \- Utility to start a message bus from a shell script
.SH SYNOPSIS
.PP
.B dbus-launch [\-\-version] [\-\-exit-with-session]
.SH DESCRIPTION
The \fIdbus-launch\fP command is used to start \fIdbus-daemon-1\fP
from a shell script. It would normally be called from a user's login
scripts. Unlike the daemon itself, \fIdbus-launch\fP exits, so
backticks or the $() construct can be used to read information from
\fIdbus-launch\fP. \fIdbus-launch\fP prints information about the
launched daemon in KEY=VALUE format.
.PP
See http://www.freedesktop.org/software/dbus/ for more information
about D-BUS. See also the man page for \fIdbus-daemon-1\fP.
.PP
Here is an example of how to use \fIdbus-launch\fP with an
sh-compatible shell:
.nf
VARIABLES=`dbus-launch`
eval $VARIABLES
echo "D-BUS per-session daemon address is: $DBUS_SESSION_BUS_ADDRESS"
.fi
.SH OPTIONS
The following options are supported:
.TP
.I "--exit-with-session"
If this option is provided, a persistent "babysitter" process will be
created that watches stdin for HUP and tries to connect to the X
server. If this process gets a HUP on stdin or loses its X connection,
it kills the message bus daemon.
.TP
.I "--version"
Print the version of dbus-launch
