使用Python脚本发送电子邮件输出并使用crontab每周发送一次

Question

I have a Python script and I am trying to write a crontab and have the output from the Python script to be outputed to a file which then sends that output to an email address (to the body of the email not the title) that is specified. My system details and crontab entry is below:

System details:
Python: 2.7
OSX : 10.11


host$ crontab -l
11 11 13 10 4 2016 python pythonscript.py >> weekly.log | mail -s weekly.log     myemail@.com

Although when the crontab executes, the email sends me an email message with the subject line saying "weekly.log" with no body.

I have also tried crontab with below settings:

07 22 13 10 4 2016 /root/python/osversion_weekly.py | tee   /root/python/osversion`date +\%Y-\%m-\%d-\%H:\%M:\%S`-cron.log | mailx -s "OSLEVEL Report" mymail@server.com

Although I only get an email with Title "OSLEVEL Report" with an empty body

Update: The error I seem to be getting from /var/log/cron is showing "orphan no passwd entry." Not quite sure what does means, and I havent seen any answers online to resolve this...

Answer 1

The >> makes the python output get appended to the file weekly.log , after that no input is pushed forward to mail .

You could remove >> weekly.log and not have a log file or use the program tee in the pipe. tee writes to standard output and a file.

Like this:
python pythonscript.py | tee -a weekly.log | mail -s weekly.log myemail@.com
