+# upgrade_unifi_controller.sh
+# Easy UniFi Controller Upgrade Script for Unix/Linux Systems
+# by Steve Jenkins (stevejenkins.com)
+# Version 2.3
+# Last Updated January 8, 2017
+
+# REQUIREMENTS
+# 1) Assumes you already have any version of UniFi Controller installed 
+#    and running on your system.
+# 2) Assumes a user named "ubnt" owns the /opt/UniFi directory.
+# 3) Requires a service start/stop script to properly shut down and 
+#    restart the UniFi controller before and after upgrade. I've written
+#    compatible startup scrips for SysV and systemd systems at 
+#    http://wp.me/p1iGgP-2wl
+# 4) Requires wget command to fetch the software from UBNT's download site.
+
+# USAGE
+# Modify the "UNIFI_DOWNLOAD_URL" variable below using the full URL of
+# the UniFi Controller zip file on UBNT's download site. Optionally modify
+# any of the additional variables below (defaults should work fine),
+# then run the script!
+
+# CONFIGURATION OPTIONS
+VERSION=$(/sbin/e-smith/db configuration getprop unifi VersionToInstall || echo "5.6.30")
