nicest way to kill python process running on linux?

[Alex Hunsley]

I'm running a monitoring script under linux written in python. It's nohup'ed so
that I can log out and it will continue running happily and so on, but
sometimes I need to kill the script before editing the source and relaunching it.
Question is, what's the nicest way to kill the python process under linux? Is a
simple 'kill [process-id]' the nicest way to do it, or is there a different
signal I should send it?

It's a matter of convention, e.g. xinetd uses the USR2 signal.
Unless you use kill -9 which can't be handled by the application
anything is fine if the user knows what signal to send and your script
catches the signal to stop gracefully.

If you want to be really nice, kill -SIGINT [pid] will generate a
KeyboardInterru pt in Python that can be caught by the Python program, but
the program could be set to ignore it. Otherwise kill [pid] (equivalent
to kill -SIGTERM [pid]) is nice enough (it allows Python to do cleanup,
etc.).
