When script is added to object, the script is always empty (Ubuntu problems)

I switched to Ubuntu recently and wanted to start with Unity. Now i watched some Tutorials about Scripting and wanted to add some functionality to a simple sphere. I wrote the script in Atom and added it to a Script folder i generated in the assets. If i drag drop now the script to an object, the script cannot be runned. If i open the script it is always empty. Why is that?

Code i wanted to add:

 #pragma strict
 
 // First always define the variables i want to handle with befor starting
 // with anything
 private var coffeTemperature:float = 85.0f;
 private var hotLimitTemperature:float = 70.0f;
 private var coldLimitTemperature:float = 40.0f;
 
 
 function Update()
 {
   if(Input.GetKeyDown(KeyCode.Space))
     TemperatureTest();
 
   coffeTemperature -= Time.deltaTime * 5.0f;
 }
 
 function TemperatureTest()
 {
   //This function is only here to compare given values
   if( coffeTemperature > hotLimitTemperature )
   {
     print![("Coffe is waaaay to hot!");
   }][1]
 
   else if( coffeTemperature < coldLimitTemperature)
   {
     print("Coffe is waaay to cold !");
   }
 
   else
   {
     print("The Coffe is just fine! ");
   }
 
 }
