 <p>When Clink is injected, it looks for a <code>clink_start.cmd</code> script in the binaries directory and <a href="#filelocations">profile directory</a>.  Clink automatically runs the script(s), if present, when the first CMD prompt is shown after Clink is injected and before any Lua scripts run.  You can set the <code><a href="#clink_autostart">clink.autostart</a></code> setting to run a different command, or set it to &quot;nul&quot; to run no command at all.</p>
