<refsect1 id='description'><title>DESCRIPTION</title>
<para><command>dbus-run-session</command>
is used to start a session bus instance of
<emphasis remap='B'>dbus-daemon</emphasis>
from a shell script, and start a specified program in that session. The
<emphasis remap='B'>dbus-daemon</emphasis>
will run for as long as the program does, after which it will terminate.</para>
<para>One use is to run a shell with its own
<emphasis remap='B'>dbus-daemon</emphasis>
in a text‐mode or SSH session, and have the
<emphasis remap='B'>dbus-daemon</emphasis>
terminate automatically on leaving the sub‐shell, like this:</para>
<para> dbus-run-session -- bash</para>
<para>or to replace the login shell altogether, by combining <command>dbus-run-session</command>
with the <emphasis remap='B'>exec</emphasis> builtin:</para>
<para> exec dbus-run-session -- bash</para>
<para>Another use is to run regression tests and similar things in an isolated
D-Bus session, to avoid either interfering with the "real" D-Bus session
or relying on there already being a D-Bus session active, for instance:</para>
<para> dbus-run-session -- make check</para>
