<h1> The <tt>s6-sudo</tt> program </h1>
<p>
<tt>s6-sudo</tt> connects to a Unix domain socket and passes
its standard file descriptors, command-line arguments and
environment to a program running on the server side, potentially
with different privileges.
</p>
<h2> Interface </h2>
<pre>
s6-sudo [ -q | -Q | -v ] [ -p <em>bindpath</em> ] [ -l <em>localname</em> ] [ -e ] [ -t <em>timeoutconn</em> ] [ -T <em>timeoutrun</em> ] <em>path</em> [ <em>args...</em> ]
</pre>
<ul>
<li> s6-sudo executes into <tt><a href="s6-ipcclient.html">s6-ipcclient</a> <em>path</em>
<a href="s6-sudoc.html">s6-sudoc</a> args...</tt> It does nothing else: it is just a
convenience program. The <a href="s6-ipcclient.html">s6-ipcclient</a> program connects
to a Unix socket at <em>path</em>, and the
<a href="s6-sudoc.html">s6-sudoc program</a> transmits the desired elements over the
socket. </li>
<li> It should be used to connect to a
<a href="localservice.html">local service</a> running the
<a href="s6-sudod.html">s6-sudod</a> program, which will run a server program on the
client's behalf. </li>
</ul>
<h2> Options </h2>
<ul>
<li> The <tt>-q</tt>, <tt>-Q</tt>, <tt>-v</tt>, <tt>-p</tt> and <tt>-l</tt>
options are passed to <a href="s6-ipcclient.html">s6-ipcclient</a>. </li>
<li> The <tt>-e</tt>, <tt>-t</tt> and <tt>-T</tt> options are passed to
<a href="s6-sudoc.html">s6-sudoc</a>. </li>
<li> Command-line arguments, if any, are also passed to
<a href="s6-sudoc.html">s6-sudoc</a>, which will transmit them to
<a href="s6-sudod.html">s6-sudod</a> over the socket.
</ul>
