Python script to kill a process by its name

kill_process.py

import os, signal

def check_kill_process(pstring):
    for line in os.popen("ps ax | grep " + pstring + " | grep -v grep"):
        fields = line.split()
        pid = fields[0]
        os.kill(int(pid), signal.SIGKILL)

or you could just import the subprocess module, have the user enter a string based input, convert it to int, then via the sys module [ sys.stdin.readline()] or raw_input depending on the version of python, then create a variable to store the input with the 'killall' command, through the subprocess.call() function

Where do you list the name of the process you want to kill?!?!?! OMG....I've been searching for an hour!!!!

You can use psutil's process_iter() to list processes, and use each process's name() and cmdline() method to get its name and command line arguments.
For example, this gist implements a few functions that list processes by name or by filtering on their command line arguments.
