# How to save the result in the Notebook (.nb) and shut down the computer when the calculation is done

I have a notebook(.nb) which its calculation is time-consuming and long. I can not observe it if the calculation is done or not. Therefore, I want to :

(1) Save the results in the notebook(.nb) ( I do not want to save the data in a .Xls,.CSV,... file) and then (2) Use a command in that notebook(.n) to shut down the computer from Mathematica when the calculation and saving the data is done.

I wonder if you could possibly help me with this problem.

P.S: I have already searched the documentation and found NotebookSave[] command, but I'm not sure if it is a proper command to save the notebook. However, I couldn't find anything relate to shuting down the computer after calculation.

I think a similar question has been asked before, but I neither remember it clearly nor the solution if any was given. –  Mr.Wizard Aug 6 at 17:50
I suspect best way to shut down will be to use a command line script. What OS are you running? –  Mr.Wizard Aug 6 at 17:53
@Mr.Wizard: The OS is " Windows 8 ". So you mean there is no way ?! –  Shellp Aug 6 at 17:57
@Mr.Wizard - I think you may have remembered: this –  Jagra Aug 6 at 18:20
How about this? Run[...] should work. –  Öskå Aug 7 at 9:53
