"No magerun installed?" oneliner from README.php is not working in Bash

See: https://github.com/gwillem/magevulndb#no-magerun-installed

This does not work in Bash.
The PHP code is between "double quotes", so Bash will replace all $variables by the value of the variable in Bash, of by nothing if not defined.

Example:

/path/to/httpdocs$ php -r "require_once('app/Mage.php');Mage::app();$config=Mage::getConfig()->getNode()->modules;$found=array();$list=fopen('https://raw.githubusercontent.com/gwillem/magevulndb/master/magento1-vulnerable-extensions.csv','r');while($list&&list($name,$version)=list($row['module'],$row['fixed_in'],,$row['reference'],$row['update'])=fgetcsv($list)){if(isset($name,$version,$config->{$name},$config->{$name}->version)&&(empty($version)||version_compare($config->{$name}->version,$version,'<'))){$found[]=$row;}}if($found){echo 'Found possible vulnerable modules: '.print_r($found,1);}else{echo 'No known vulnerable modules detected.';}"
PHP Parse error:  syntax error, unexpected '=', expecting end of file in Command line code on line 1

Parse error: syntax error, unexpected '=', expecting end of file in Command line code on line 1

PHP complains here because $config is removed so the remaining statement is =Mage::getConfig()->getNode()->modules;
