<title>Description</title>
<para><command>systemd-stdio-bridge</command> implements a proxy between STDIN/STDOUT and a D-Bus bus. It
expects to receive an open connection via STDIN/STDOUT when started, and will create a new connection to
the specified bus. It will then forward messages between the two connections. This program is suitable
for socket activation: the first connection may be a pipe or a socket and must be passed as either
standard input, or as an open file descriptor according to the protocol described in
<citerefentry><refentrytitle>sd_listen_fds</refentrytitle><manvolnum>3</manvolnum></citerefentry>. The
second connection will be made by default to the local system bus, but this can be influenced by the
<option>--user</option>, <option>--system</option>, <option>--machine=</option>, and
<option>--bus-path=</option> options described below.</para>
<para><citerefentry><refentrytitle>sd-bus</refentrytitle><manvolnum>3</manvolnum></citerefentry> uses
<command>systemd-stdio-bridge</command> to forward D-Bus connections over
<citerefentry project='die-net'><refentrytitle>ssh</refentrytitle><manvolnum>1</manvolnum></citerefentry>,
or to connect to the bus of a different user, see
