I'm trying to execute a python script using the linux crontab, but i found a lot of solution and anyone works, for example edit the anacron at /etc/cron.d ou use crontab -e.

I want to run this script every 10 minutes.

What file must I edit to configure this?

Thanks in advance

EDIT

I put this line on ends of file, but doesn't changes anything. Must I restart any service?

*/2 * * * * /usr/bin/python /home/souza/Documets/Listener/listener.py

EDIT [2]

Guys, follow the source code, could be here the problem, but when i execute that manually, it works:

When you say "it doesn't change anything". Does it show an error, does it not run? What is the behaviour? –  Raul Marengo Jan 4 '12 at 15:47
    
is "Documets" instead of "Documents" intentional? –  Raul Marengo Jan 4 '12 at 15:48
    
Simply doesn't occurs anything. :( –  guisantogui Jan 4 '12 at 15:53
    
This sort of goes beyond the scope of the question but, what do you expect your "listener.py" script to do? Does it do anything that could indicate that it has run? Do ps -ef | grep 'crond' in your command line to check if cron is running. –  Raul Marengo Jan 4 '12 at 15:57
    
No, this script send several cURL's commands to another computer. When I execute the "ps -f | grep 'crond'", it returns this: "souza 4736 3947 0 14:01 pts/1 00:00:00 grep --color=auto crond" –  guisantogui Jan 4 '12 at 16:00

Just use crontab -e and follow the tutorial here:

http://adminschoice.com/crontab-quick-reference

Look at point 3 for a guide on how to specify the frequency.

Based on your requirement, it should effectively be:

*/10 * * * * /usr/bin/python script.py

I follow this tutorial, but when i save the file appears a message: "/tmp/crontab.JTQ0My/crontab":22: bad minute errors in crontab file, can't install. Do you want to retry the same edit? (y/n)" if I type "y", I've returned to file edit. And if I type "n" the file is not saved. I add this line at last line of the file: "/1 * * * * /usr/bin/python script.py" –  guisantogui Jan 4 '12 at 13:56
    
@guisantogui there is a point in the tutorial that explains that using "/1" might not be supported by all operating systems. What operating system are you running this on? –  Raul Marengo Jan 4 '12 at 14:02

@guisantogui just noticed you are missing a "*" before the "/" –  Raul Marengo Jan 4 '12 at 14:03
    
another way is to add an env declaration in your script.py. See my comments to the accepted solution at: stackoverflow.com/questions/25633737/python-crontab-and-paths –  Ryan B Sep 3 at 14:56

Put your script in a file foo.py starting with

#!/usr/bin/python

then give execute permission to that script using

chmod a+x foo.py

and use the full path of your foo.py file in your crontab
