<h1> The <tt>unexport</tt> program </h1>
<p>
<tt>unexport</tt> removes a variable from the environment, then
executes a program.
</p>
<h2> Interface </h2>
<pre>
unexport <em>var</em> <em>prog...</em>
</pre>
<p>
<tt>unexport</tt> removes the <em>var</em> variable from the
environment, then execs into <em>prog</em> with
its arguments.
</p>
<h2> Notes </h2>
<ul>
<li> Unsetting <em>var</em> is quite different from setting it to an
empty value. Shell scripts usually won't make the distinction;
execline does. </li>
</ul>
