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 + " ")
sys.stdout.flush()
sys.stdout.write("\b\b")
time.sleep(delay)
pid = os.fork()
if pid == 0:
os.execvp("du",("du","-shc","/"))
else:
spin(0.05)
However, the spinner is kept spinning even the child process was ended.
Any idea ? Thanks!
