What does >& mean here?
<p>I have C code, that has been compiled. Then I have to execute from command line </p>

<pre><code>../../../PStomo_eq665/pstomo_eq par=syn.par &gt;&amp; log.syn
</code></pre>

<p>What does <code>&gt;&amp;</code> mean in this context? Both files <code>syn.par</code> and <code>log.syn</code> contain parameters for <code>pstomo_eq</code>.</p>
