RE: Terminate a python script from linux shell / bash script

>>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.
>GBSo, is there a way from the Linux shell or a bash script to terminate
GBjust one specific Python script ?
>>So just kill it.
Yes I've seen that each python script calls its own instance of Python. Buthow to know which is the good one in bash ? Is there a command that gets the parameters of process, so I could use grep to select the one containing the name of my script ?

The ps command will usually give you a list of the running processes with
their argument, but using that is suboptimal.

I suppose you start the process in the background, like: python myscript &.
When you start the python script in bash (or any other process for that
matter) in the background you can get the process id (pid) with $!
(immediately after starting the process). Later on you can use this to kill
the process:

python myscript myargs &
savepid=$!
later: kill $savepid

That is much better than trying to grep through the ps output.
