+title: "rfi: A Simple Linux utility to get a random file from a directory"
+layout: post
+---
+
+I made a [little video](https://lbry.tv/@tait:7/rfi:5) about this script I wrote:
+
+<pre class="terminal">
+$ rfi
+</pre>
+
+This program gets a random file from your current directory
+if you do not specify one;
+it gets a random file from the specified directory if you give it one like so:
+
+<pre class="terminal">
+# rfi /etc/wireguard
+</pre>
+
+Which is very useful if you want to start a random VPN configuration :)
+
+The code, comments, etc. are on the [Github](https://github.com/TTWNO/scripts).
