+<h1>Running via the CLI</h1>
+
+<p>
+ As well as calling an applications <a href="./controllers.html">Controllers</a> via the URL in a browser they can also be loaded via the command-line interface (CLI).
+</p>
+

+<h2>What is the CLI?</h2>
+
+<p><dfn>The command-line interface is a text-based method of interacting with computers that looks like what most people remember as DOS.</dfn></p>
+
+<a name="why"></a>
+
+<h2>Why run via the command-line?</h2>
+
+<p>
+ There are many reasons for running CodeIgniter from the command-line, but they are not always obvious.</p>
+
+<ul>
+ <li>Run your cron-jobs without needing to use wget or curl</li>
+ <li>Make your cron-jobs inaccessible from being loaded in the URL by checking for <kbd>IS_CLI</kbd></li>
+ <li>Make interactive "tasks" that can do things like set permissions, prune cache folders, run backups, etc.</li>
+ <li>Integrate with other applications in other languages. For example, a random C++ script could call one command and run code in your models!</li>
+</ul>
+
+<a name="how"></a>
+<h2>Let's try it:&nbsp; Hello World!</h2>
+
+<p>Let's create a simple controller so you can see it in action. Using your text editor, create a file called <dfn>tools.php</dfn>, and put the following code in it:</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="10">
+&lt;?php
+class Tools extends CI_Controller {
+
+ public function message($to = 'World')
+ {
+ echo "Hello {$to}!".PHP_EOL;
+ }
+}
+?&gt;
+</textarea>
+
+<p>Then save the file to your <dfn>application/controllers/</dfn> folder.</p>
+
+<p>Now normally you would visit the your site using a URL similar to this:</p>
+
+<code>example.com/index.php/<var>tools</var>/<var>message</var>/<var>to</var></code>
+
+<p>Instead, we are going to open Terminal in Mac/Lunix or go to Run > "cmd" in Windows and navigate to our CodeIgniter project.</p>
+
+<blockquote>
+ $ cd /path/to/project;<br/>
+ $ php index.php tools message
+</blockquote>
+
+<p>If you did it right, you should see <samp>Hello World!</samp>.</p>
+
+<blockquote>
+ $ php index.php tools message "John Smith"
+</blockquote>
+
+<p>Here we are passing it a argument in the same way that URL parameters work. "John Smith" is passed as a argument and output is: <samp>Hello John Smith!</samp>.</p>
+
+<h2>That's it!</h2>
+
+<p>That, in a nutshell, is all there is to know about controllers on the command line. Remember that this is just a normal controller, so routing and _remap works fine.</p>
