how to run a python program in linux crontab?

Question

I have added the following line in contab

 1 * * * * /usr/bin/python /home/prkumar/Desktop/python/sample.py

my sample.py file

  text_file = open("sample.log", "a")
  text_file.write("Hi...")
  text_file.write("\n")
  text_file.close()

If I run the python program in terminal it's working fine and also append the text in sample.log file. But there is no response if add the program in crontab.

Thanks

maybe with python shebang as first line? en.wikipedia.org/wiki/Shebang_(Unix)#Examples — mkind

You need a correction :

* * * * * /usr/bin/python /home/prkumar/Desktop/python/sample.py

to run it every minute.

Your cron statement : 1 * * * * /usr/bin/python /home/prkumar/Desktop/python/sample.py

would run it only at first minute of every hour eg 09:01, 10:01...etc. Hence, you will have to wait 1 hour to see the result.

github.com/homer6/frequent-cron if you want to run more frequently than once a minute...

@sasi Why was the other answer voted as correct answer ? Was that the actual problem you were facing instead of this ?

you should use */1 * * * * to run every minute, 1 * * * * runs first minute of every hour..

change python instead of /usr/bin/python, Change your code as follows.

1 * * * * python /home/prkumar/Desktop/python/sample.py >> /home/prkumar/Desktop/python/output.log
