<h1> The <tt>execline-cd</tt> program </h1>
<p>
<tt>execline-cd</tt> changes the current working directory to a
given directory, then executes a program.
</p>
<h2> Interface </h2>
<pre>
execline-cd <em>dir</em> <em>prog...</em>
</pre>
<p>
<tt>execline-cd</tt> performs a
<a href="https://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>
<ul>
<li> By default, <tt>execline-cd</tt> can also be invoked as <tt>cd</tt>:
there is a <tt>cd</tt> program which is a symbolic link to <tt>execline-cd</tt>. </li>
<li> When execline has been configured with the <tt>--enable-pedantic-posix</tt>
option, the <tt>cd</tt> binary is a symbolic link to the
<a href="posix-cd.html">posix-cd</a> binary instead, so a <tt>cd</tt> command
in an execline script will invoke <a href="posix-cd.html">posix-cd</a> instead
of <tt>execline-cd</tt>. </li>
<li> Existing scripts that call <tt>cd</tt> will keep working no matter the
chosen configuration. </li>
</ul>
