I have rewrited my code as follow, but it still not working.
import os, sys
pid = os.fork()
if pid == 0:
os.execvp("du",("du","-shc","/usr/share"))
else:
while 1:
try:
os.kill(pid,0)
sys.stdout.write('running')
sys.stdout.flush()
sys.stdout.write('\b\b\b\b\b\b\b'

I am trying to fork and exec a child by python. Additionally, I am
attempting
to have a spinning slash while the child is running.
My code is as below:
import sys, os, time
def spin(delay):
pattern=['-','\\','|','/','-','\\','|']
while 1:
for i in pattern:
sys.stdout.write(i + "
