I am trying to kill java process with name "MyClass" using below python script :
import os
os.system("kill $(ps aux | grep 'MyClass' | grep -v 'grep' | awk '{print $2}')")
But this gives me output as below and the process is still running
sh: 1: kill: Usage: kill [-s sigspec | -signum | -sigspec] [pid | job]... or
kill -l [exitstatus]
512
I know that the $ sign is the problem here but do not know how to make this work.
Any help/hint is appreciated. Thanks.
def terminate_java_process(process_name):
proc = subprocess.Popen(["jps"], stdout=subprocess.PIPE, shell=True)
(out, err) = proc.communicate()
processes = {}
for line in out.split(b"\n"):
try:
process_name=str(line, 'utf-8').split(' ')[1]
except:
continue
process_id= str(line, 'utf-8').split(' ')[0]
processes[process_name] = process_id
os.system("kill -s TERM 82220")
Here I have another way:
I am fetching all the processes, by looping each one I'm taking the required one and if it is found just kill them.
I am making use of these concept to find out how many processes are running for the same client, for the same category.
# this will fetch the processes in stdout var
processes = Popen(['ps', '-ef'], stdout=PIPE, stderr=PIPE)
stdout, error = processes.communicate()
for line in stdout.splitlines():
if (line.__contains__("Process_name to check")):
pid = int(line.split(None, 1)[0])
os.kill(pid, signal.SIGKILL)
ps aux | grep 'MyClass' | grep -v 'grep' | awk '{print $2}')?
