What operating system is my server running?
How can you tell what operating system and version your Magento server runs?
Prerequisites: You must access the server using a command prompt (an application that enables you to enter commands directly).
If you can log in directly to the machine, the application is usually called Terminal.
If you cannot log in directly, you can log in remotely.
