Question

I am writing a script to email the owner of a file when a separate process has finished. I have tried:

import os
FileInfo = os.stat("test.txt")
print (FileInfo.st_uid)

The output of this is the owner ID number. What I need is the Windows user name.

Answer 1

Once I stopped searching for file meta data and started looking for file security I found exactly what I was looking for.

import tempfile
import win32api
import win32con
import win32security

f = tempfile.NamedTemporaryFile ()
FILENAME = f.name
try:
  sd = win32security.GetFileSecurity (FILENAME,win32security.OWNER_SECURITY_INFORMATION)
  owner_sid = sd.GetSecurityDescriptorOwner ()
  name, domain, type = win32security.LookupAccountSid (None, owner_sid)

  print "I am", win32api.GetUserNameEx (win32con.NameSamCompatible)
  print "File owned by %s\\%s" % (domain, name)
finally:
  f.close ()
