<p>
<tt>fdclose</tt> closes a given file descriptor, then
executes a program.
</p>

<h2> Interface </h2>

<pre>
     fdclose <em>fd</em> <em>prog...</em>
</pre>

<p>
<tt>fdclose</tt> closes the file descriptor number <em>fd</em>, then
execs into <em>prog</em> with its arguments.
</p>

<h2> Notes </h2>

<tt>sh -c 'exec prog... <em>n</em>&lt;&amp;-'</tt></li>
</ul>
