Create a simple cylinder using command-line FreeCAD

I would like to create a simple pillar in FreeCAD using python and the export it as .stl file What have I done so far?

1. Recorded a macro of me creating a cylinder (Part) and exporting it as an stl file.
2. I copy and paste the text from the macro into a python file, which I named "pillar.py"

Here is the code:

# -*- coding: utf-8 -*-

+++++++++++++++++++++++++++++++++++++++++++++++++
import FreeCAD
import Part
import Mesh


App.ActiveDocument.addObject("Part::Cylinder","Cylinder")
App.ActiveDocument.ActiveObject.Label = "Cylinder"
App.ActiveDocument.recompute()

__objs__=[]
__objs__.append(FreeCAD.getDocument("Unnamed").getObject("Cylinder"))
Mesh.export(__objs__,u"C:/Users/totyped/Desktop/pillar_2.stl")

del __objs__
+++++++++++++++++++++++++++++++++++++++++++++++++

3. I closed the GUI and open the terminal, and I type:
   "C:\Program Files\FreeCAD 0.18\bin\FreeCADCmd.exe" "C:\Users\totyped\Documents\pillar.py"
   

Source: https://forum.freecadweb.org/viewtopic.php?t=23869
The result: It just shows this on the terminal, but does not create any stl file.

It also does not give any warning or error message...
Any help to make this work, would be highly appreciated.
IMPORTANT: SO, I noticed that it will work, if I put the script file into the same directory as FreeCADmd.exe. Why ? I have no clue...
EDIT: So, as suggested by @sliptonic I tried to change the script file to:

import FreeCAD
import Part
import Mesh

App.newDocument("Unnamed")
App.ActiveDocument.addObject("Part::Cylinder","Cylinder")
App.ActiveDocument.ActiveObject.Label = "Cylinder"
App.ActiveDocument.recompute()

__objs__=[]
__objs__.append(FreeCAD.getDocument("Unnamed").getObject("Cylinder"))
Mesh.export(__objs__,u"pillar_2.stl")

del __objs__

but I still did not get any cylinder. Maybe the log file can help? Here it is:

It's weird because if I run is as a macro from within the FreeCAD GUI it works and creates the .stl cylinder
