how to retreive PID of specific python script using pidof
 

Hello,

Im trying to write a simple script that will only launch a process if it is not already running.

I want to use the return value from 'pidof' to find out whether it is running.

However the process i am looking for is a script launched with python. Thus if I use "pidof python" I get multiple PIDs returned which is no use.

I also thought of using return value from grep <script.py> but this returns the grep process aswell.. argh!

Any ideas?

Nevermind,

if you do a:

ps ax | grep -v grep | grep process

the middle command removes the grep process running from the list. You can then use the return result from this to branch your if statement
