Python executing commands in the command prompt (taskkill)

Question

I'm trying to use os.system to use the taskkill command in command prompt. ill gut out the only part im having trouble with:

os.system('taskkill /s %s /u CORP\Administrator /p CLARiiON! /pid AxAuto.exe'%(connection[i]))

The variable connection[i] is just an IP Address of a remote computer on the same network. I can run this command straight from the command prompt locally and just directly input the IP and I know for a fact it will work, But running the command through Python in this format returns "> was unexpected at this time." Am I making a silly formatting mistake in this line of code? the error can be seen below:

EDIT: I've also been told to use the Subprocess module. i tried the snippet below:

command="taskkill /s %s /u CORP\Administrator /p CLARiiON! /im AxAuto.exe"%(connection[i]))
subprocess.Popen(command, stdout= subprocess.PIPE, stdin = subprocess.PIPE, stderr=subprocess.PIPE)

It doesnt fail in the script but it also doesnt kill the process.

can you provide the exact error you're getting? Is the error a Windows error or a Python error? Also you may want to use the subprocess module instead of os.system. — notorious.no

@notorious the error I get is shown in the Python script window, there is no trace back it only says "> was unexpected at this time." when it executes the command — bladexeon

@bladexeon I hope you are aware that you have posted the password in your python code! ;-) — ρss

The /pid argument should be an integer value. You may use /img for an image name of the process. microsoft.com/resources/documentation/windows/xp/all/proddocs/… — ρss

@pss But I have used the name of the process in a normal Windows cmd prompt and it worked saying "Process xxx has been killed" or something like that so I know this will work — bladexeon

Try something like the code below:

from subprocess import call

call(['taskkill', '/s', connection[i], '/u', 'CORP\Administrator', '/py',
      'CLARiiON!', '/pid', 'AxAuto.exe'])

This one gave me: raise TypeError("This object does not support enumeration")

notorious.no Over a year ago

This may be caused by connection. What do you get when you print connection[i]

bladexeon Over a year ago

Aha! gives me this: <_wmi_namespace: ,COMObject <unknown>>> this coming from a different part of the code...also being ssomething i have no idea how to fix

I don't think you need to "fix" it, you just need to figure out how to get the IP address from that object or even if it's possible.

I figured out the error I was using a WMI connection variable instead of the raw IP variable, and It did work with Subprocess. Thanks Much!
