Example of export script from MODX Resources to JSON, for importing to another site.

/**
 * config.json
 * @description: JSON array of objects with three required keys
 * "class" is the class of MODX object you wish to export, from the array $allowed
 * "where" is the criteria on which to search for the object. 
 * "toWhere" is the criteria on which to search for the object to replace in the target site.
 * Special flags for "toWhere" include: 
 * "create" which will discard the ID and create a new object using fromArray(). 
 * NOTE: issues may arise from duplicate field values, such as "name".
 * "update" which will use the same criteria as supplied in "where" on the target site.
 * Any fals-ey value, or non-array, other than the special flags, will result in the object
 * being excluded from the export.

Hi,
How do I execute this via SSH in a localhost (XAMPP) ?
