从Bash或Python检查邮件主题

Question

I have many cron jobs running on various servers, I want to check the status of the jobs via mail using command line. The only way seems to me is to extract the subject or body of the mail the jobs sent. cron will send mail regardless of the success or failure.

For example, upon success cron will send a mail with subject:

Done..succeeded

If failed:

Not done..Failed

The cron jobs run at specific times eg lets take 10:00, 16:00 and 22:30 everyday.

I have tried curl and urllib2 but could not get desired result. Also note that i can not make any modification to cron itself, the only option is to check the gmail.

So how can i check my gmail from bash or python to extarct the subject so that i get get an idea of the cron job?

Answer 1

You can use imaplib to talk to Gmail with the IMAP protocol. This is the same protocol that you would use to have Gmail work with eg Thunderbird, so it's fairly easy to retrieve messages rather than dealing with scraping often-changing HTML.

Answer 2

I had some python code that used to check gmail for me. I was going to post it but I tried it out and it no longer works for me. I haven't used it for about a year and Gmail has updated their auth to use oauth2 which is more secure. You may be able to get imaplib to work as well but you will need to enable less secure apps on your gmail account. If I have time to tweak it and get it working I will post it. In the meantime this link looks like a pretty good walk-through of how to get it working. https://github.com/google/gmail-oauth2-tools/wiki/OAuth2DotPyRunThrough
