Often you will need to know which version of Magento you are running in order to install an extension or apply a security patch. Heres how to find the Magento version you are running.
< ?php
include 'app/Mage.php';
echo 'Magento version is: ', Mage::getVersion();
Alternatively, from the command line you can use:
cd public_html
/public_html$ php -a
Interactive shell
php > include 'app/Mage.php';
php > echo Mage::getVersion();
1.6.2.0
php >exit();
