Terminate a python script from linux shell / bash script

[Gros Bedo]

Hello

I have a question about Python and Linux shell. I have a python program which is permanently resident in the end-user system. I'm currently producing a RPM package, and it works nicely. The problem is that when I uninstall it, my program keeps running in the background, even if the files are deleted.

I know I can terminate python shell directly, but this is not a good idea because the end-user may be working with another important python application, and would be very angry if mine would close everything that is using python shell.

So, is there a way from the Linux shell or a bash script to terminate just one specific Python script ?

You should use the signal module to look for SIGINT signal and exit if it is
received.

An alternative, though crude, hack is for the script to check for the
existence (or non-existence) of a special file and quit if found (or
not found). It could also create it when it starts or delete it when
it quits, as appropriate.

That's not how it works. If you kill one running python script it will not
effect other python scripts. Each script has its own interpreter process
running.

So just kill it.
