<h1> The <tt>cd</tt> program </h1>
<p>
<tt>cd</tt> changes the current working directory to a
given directory, then executes a program.
</p>
<h2> Interface </h2>
<pre>
cd <em>dir</em> <em>prog...</em>
</pre>
<p>
<tt>cd</tt> performs a
<a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/chdir.html">chdir()</a>
system call on <em>dir</em>, then execs into <em>prog...</em>.
</p>
<h2> Notes </h2>
<p>
<tt>cd</tt> is a standard shell builtin. Be careful if you want to
use the <tt>cd</tt> command outside of an <tt>execline</tt> script.
