<h1> The <tt>s6-dumpenv</tt> program </h1>
<p>
s6-dumpenv stores its environment variables into a directory.
</p>
<h2> Interface </h2>
<pre>
s6-dumpenv [ -N | -n ] [ -m <em>mode</em> ] <em>dir</em>
</pre>
<ul>
<li> s6-dumpenv creates the directory <em>dir</em> if it does not exist
yet. </li>
<li> For every environment variable <em>x</em> with value <em>y</em>
that it has, it creates a file <em>dir</em>/<em>x</em> containing
<em>y</em>. </li>
<li> It then exits 0. </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-N</tt> : chomp. Write the environment variables with an
extra newline at the end, so the environment can be retrieved via
<tt>s6-envdir -Lf <em>dir</em></tt>. </li>
<li> <tt>-n</tt> : Write the environment variables as is; the
environment will be retrieved via <tt>s6-envdir -Lfn <em>dir</em></tt>.
This is the default. </li>
<li> <tt>-m</tt> <em>mode</em> : create <em>dir</em> with
mode <em>mode</em> if it doesn't exist yet. Default is 0755. </li>
</ul>
<h2> Notes </h2>
<ul>
<li> A program <em>prog</em> can be run with the environment in dir
by using <tt><a href="//skarnet.org/software/s6/s6-envdir.html">s6-envdir</a>
-fn -- <em>dir</em> <em>prog</em></tt>. </li>
</ul>
