Python: Listen to Process Started

While copying large data files over network drives:

cmd=None
if sys.platform.startswith("darwin"): cmd=['cp', source, dest]
elif sys.platform.startswith("win"): cmd=['xcopy', source, dest, '/K/O/X']
if cmd: proc = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

I wonder if there's a way to hook to started process to get feedback: such as a network transfer data rate... any suggestions?

I am not sure what the "feedback" means but you can get the current status of copy by using multithreading.

You can have one thread who keeps doing 

du -h file_name

This should do what you want it to :)

if cmd:
  proc = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
  result = proc.communicate()[0]
  print result

this should do what you want.
