<h1> The <tt>getpid</tt> program </h1>
<p>
<tt>getpid</tt> stores its process ID in a given environment variable,
then executes a program.
</p>
<h2> Interface </h2>
<pre>
getpid [ -E | -e ] [ -P | -p ] <em>var</em> <em>prog...</em>
</pre>
<p>
<tt>getpid</tt> stores its PID in the <em>var</em> variable, then
execs into <em>prog</em> with its arguments.
</p>
<h2> Options </h2>
<ul>
<li> <tt>-e</tt> : no autoimport. This is the default. </li>
<li> <tt>-E</tt> : autoimport. Instead of exec'ing into
<em>prog...</em>, exec into <tt>importas -ui <em>var</em> <em>var</em>
<em>prog...</em></tt>. This substitutes <em>var</em> into the command
line instead of putting it into the environment. </li>
<li> <tt>-p</tt> : get the pid of the current process. This is the default. </li>
<li> <tt>-P</tt> : use <tt>getpid</tt>'s <em>parent</em> pid instead. </li>
</ul>
<h2> Notes </h2>
<ul>
<li> <em>var</em> must be given without a dollar! </li>
<li> <em>var</em> must not contain <tt>=</tt>. </li>
</ul>
