<a name="index-auto_002dloading"></a>

<p><small>GDB</small> sometimes reads files with commands and settings automatically,
without being explicitly told so by the user.  We call this feature
<em>auto-loading</em>.  While auto-loading is useful for automatically adapting
<small>GDB</small> to the needs of your project, it can sometimes produce unexpected
results or introduce security risks (e.g., if the file comes from untrusted
sources).

<p>There are various kinds of files <small>GDB</small> can automatically load.
In addition to these files, <small>GDB</small> supports auto-loading code written
in various extension languages.  See <a href="Auto_002dloading-extensions.html#Auto_002dloading-extensions">Auto-loading extensions</a>.
</p>
<p>Note that loading of these associated files (including the local <samp>.gdbinit</samp>
file) requires accordingly configured <code>auto-load safe-path</code>
(see <a href="Auto_002dloading-safe-path.html#Auto_002dloading-safe-path">Auto-loading safe path</a>).
</p>
<p>For these reasons, <small>GDB</small> includes commands and options to let you
control when to auto-load files and which files should be auto-loaded.
</p>
<dl compact="compact">
<dd><a name="set-auto_002dload-off"></a><a name="index-set-auto_002dload-off"></a>
</dd>
<dt><code>set auto-load off</code></dt>
<dd><p>Globally disable loading of all auto-loaded files.
You may want to use this command with the &lsquo;<samp>-iex</samp>&rsquo; option
(see <a href="Startup.html#Option-_002dinit_002deval_002dcommand">Option -init-eval-command</a>) such as:
</p><div class="smallexample">
<pre class="smallexample">$ <kbd>gdb -iex &quot;set auto-load off&quot; untrusted-executable corefile</kbd>
</pre></div>

<p>Be aware that system init file (see <a href="System_002dwide-configuration.html#System_002dwide-configuration">System-wide configuration</a>)
and init files from your home directory (see <a href="Startup.html#Home-Directory-Init-File">Home Directory Init File</a>)
still get read (as they come from generally trusted directories).
To prevent <small>GDB</small> from auto-loading even those init files, use the
<samp>-nx</samp> option (see <a href="Mode-Options.html#Mode-Options">Mode Options</a>), in addition to
<code>set auto-load no</code>.
</p>
<a name="show-auto_002dload"></a><a name="index-show-auto_002dload"></a>
</dd>
<dt><code>show auto-load</code></dt>
<dd><p>Show whether auto-loading of each specific &lsquo;<samp>auto-load</samp>&rsquo; file(s) is enabled
or disabled.
</p>
