如何在Linux crontab中运行python程序？

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

Answer 1

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.

更改python而不是/ usr / bin / python，如下所示更改代码。

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