Running python script before user login

[Mahmood Naderan]

It seems that changing the directory before python command is mandatory:

#!/bin/sh
cd /home/mahmood/
python sendip.py 
 
I am now able to receive the IP address right after boot and before login page. 
Thank you
// Naderan *Mahmood;

On Sunday 22 August 2010, it occurred to Mahmood Naderan to exclaim:

Where are you looking? Do you actually know in which working directory your 
script is being executed?

How about something like this:

#!/bin/sh

cd /home/mahmood/

python sendip.py >sendip.log 2>&1


... this will write Python's output to a log file. If there is an exception, 
you'd be able to see it.
