This will check for the string "Request timed out.." is NOT in a. Now
when the ping is successfull the string will not be in a. I suspect you
are looking for the logic being reversed so remove the not.

Re: [Tutor] Fwd: Executing a command from a specific directory

[Ansuman Dash]

Hi,

Thank you very much for the quick response.

Code is working fine.

Now I am trying to validate that the command is executed successfully.
I have written following script to validate the log file which is created
after running the command.


if os.access("C:/Python25/Own.log", os.F_OK):
f = open("C:/Python25/Own.log")
time.sleep(30)
try:
for line in f.readlines():
a=line

if "Request timed out.." not in a:
print("Ping is not successful.")
pLogger.info("Ping is not successful.")
else:
print ("Ping is successful.")
pLogger.info("Ping is successful.")

finally:
f.close()
else:
pLogger.info("File doesn't exist")
=

But it is not working, even if ping is successfully it is printing "Ping is
not successful.". Can you please point out where I am making mistake.

Thanks,
AD

import os
import subprocess

os.chdir('/your/directory')
p = subprocess.Popen("ls -l", shell=True, stdout=subprocess.PIPE)
out = p.stdout.read()
print out
