<h3 class="section">28.2 The Server Prefix</h3>
<p><a name="index-server-prefix-3112"></a>
If you prefix a command with &lsquo;<samp><span class="samp">server </span></samp>&rsquo; then it will not affect
the command history, nor will it affect <span class="sc">gdb</span>'s notion of which
command to repeat if &lt;RET&gt; is pressed on a line by itself. This
means that commands can be run behind a user's back by a front-end in
a transparent manner.
<p>The <code>server </code> prefix does not affect the recording of values into
the value history; to print a value without recording it into the
value history, use the <code>output</code> command instead of the
<code>print</code> command.
<p>Using this prefix also disables confirmation requests
(see <a href="confirmation-requests.html#confirmation-requests">confirmation requests</a>).
