[TYPO3-english] Is there a condition to check the OS of the server?

[Christopher]

Hi guys,

I want to set a variable depending on the operating system used on the 
server(!).
Namely: I want to seperate Linux from Windows.

I know there is the condition [system = ], but this only checks the OS which 
the website-visitor runs.

Is there a way to check the system of the server?

Kind regards

Christopher
