Finding Joomla Installs and Checking Version (BASH)

Category: BASH

A small BASH script, suitable to be run as a cron job, to find Joomla installs and get the version from version.php. Can be piped into mail to generate an alert if needed

You can override the default variables by setting them within the environment. Available variables are

  • PHP - The PHP binary to call (default php5-cli)
  • VERSION_FILE - The Joomla version file to look for (default version.php)
  • WEBDIR - The directory to search within (default /home)
  • DEBUG - Enables debug mode (default n)
WEBDIR="/var/www/html"
export WEBDIR
./check_joomla_versions.sh
