Here's a way (there are many):

ps -ef | grep 'cepusender/main.py' | grep -v grep | awk '{print $2}' | xargs kill
  • ps is the process snapshot command. -e prints every process on the system, and -f prints the full-format listing, which, germanely, includes the command line arguments of each process.
  • grep prints lines matching a pattern. We first grep for your file, which will match both the python process and the grep process. We then grep -v (invert match) for grep, paring output down to just the python process.

Output now looks like the following:

user      77864   68024  0 13:53 pts/4    00:00:00 python file.py
  • Next, we use awk to pull out just the second column of the output, which is the process ID or PID.
  • Finally we use xargs to pass the PID to kill, which asks the python process to shutdown gracefully.

kill is the command to send signals to processes.

You can use kill -9 PID to kill your python process, where 9 is the number for SIGKILL and PID is the python Process ID.
