How to Modify a Cronjob Email Subject

Solution 1:

Or use the sh noop command (:)

0 9-17 * * 1-5    : Queue Summary; PATH=/usr/sbin qshape

The subject still looks kludgey, but at least it's descriptive and requires no extraneous scripts.

Solution 2:

Pipe your cron job output to mail directly, and then you can fill in the subject line. the 2>&1 syntax sends any error output which would otherwise disappear.

mycmd 2>&1 | mail -s "mycmd output" myname

Solution 3:

Take over crond's responsibility for sending command output (or not if there isn't any) by piping output and stderr into 'mailx -E'. For example:

0 * * * * your-command 2>&1 | mailx -E -s "Descriptive Subject" $LOGNAME

Mailx's '-E' option is nice because, just like crond itself, it won't send a mail if there isn't any output to send.

Solution 4:

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.

Solution 5:

Another solution is to write a shell script with the subject line you want that calls the right command. In your example, this would be:

#Optimize_MySQL_Database.sh

/ramdisk/bin/php5 -c /home5/username/scheduled/optimize_mysql.bash

You can include your bin directory in the path by setting it in the crontab file.
