Debian – Cronjob change email subject and sender name

crondebianemail

I have a cronjob setup using crontab that looks like this…

MAILTO=myemail@example.com
00 02 * * * /home/myaccount/myscript.sh

This works great and at 2AM it runs the script and emails me the output to myemail@example.com

The only issue is that the email subject and the name of the sender aren't very useful.

Is there a way to change them in the same way i can set the recipient email address?

Can I suppress the automatic email and pipe the output to mail myself?

Cron doesn't allow for a lot of configuration, but you can do this, assuming you have the mailutils package installed:

00 02 * * * /home/myaccount/myscript.sh 2>&1 | mail -s "My subject" $MAILTO

Cron – How to Modify a Cronjob Email Subject

On my systems (most Debian) all output, from a script/program called as a crontab-entry, is sent by email to the account@localhost who initiated the cron. These emails have a subject like yours.

If you want to receive an email, write a script that has no output on its own. But instead put all output in a textfile.

And with

mail -s 'your subject' adress@where < textfile

you receive it the way you want.

Actually, I think you've done the exact reverse of what you wanted; you've suppressed the error messages (by sending STDERR to /dev/null) and will get only the normal output.

Try

24 4 * * * root /usr/sbin/ntpdate pool.ntp.org > /dev/null

Better still, run ntpd; it's a much better way of keeping your clocks in sync than brute-force resetting them once a day.
