<h2>GOOD-BYE</h2>quit entirely out of Lisp
<pre>Major Section:  <a href="OTHER.html">OTHER</a>
</pre><p>


<pre>
Example:
ACL2 !&gt;:good-bye
</pre>

<strong>Note:  Your entire session will disappear forever when you type</strong>
<code>:good-bye</code>.
<p>
The command <code>:good-bye</code> quits not only out of the ACL2 <a href="COMMAND.html">command</a> loop,
but in fact quits entirely out of the underlying Lisp.  Thus, there
is no going back!  You will <strong>not</strong> be able to re-enter the <a href="COMMAND.html">command</a> loop
after typing <code>:good-bye</code>!  All your work will be lost!!!<p>

This command may not work in some underlying Common Lisp
implementations.  But we don't expect there to be any harm in
trying.  It <strong>does</strong> work in GCL and Allegro CL, at least as of
this writing.<p>

In some systems, typing <code>control-d</code> at the top-level ACL2 prompt
(<code>control-c control-d</code> if inside emacs) will call this function.<p>

If you merely want to exit the ACL2 <a href="COMMAND.html">command</a> loop, use <code>:</code><code><a href="Q.html">q</a></code> instead
(see <a href="Q.html">q</a>).
