Python cronjob won't run

问题

When I am SSH'd into my Ubuntu 6.4 VM and run python nomi.py, my script executes as it should.

I set up my crontab file as follows in order to run the script every 15 mins:

# m h  dom mon dow   command

*/15 * * * * /usr/bin/python home/cron1admin/nomi.py

Is there anything wrong with how I set up the crontab file? Do I need to do anything after the crontab file is created?

The nomi.py file sends data to Google Analytics, and when I run the script, the data goes through. When I attempt to let the cron job run the script, nothing happens.

The following question suggests that you should use absolute paths instead of relying on ~ to expand to your home directory.

Also make sure cron is actually running. You can do this by grepping for the cron process. On Ubuntu Linux, I usually use the following command.

ps aux | grep cron
