Cron Job Email Notification
errors in emails? up vote 22 down vote favorite 5 I finally set up a realistic backup schedule on my data through a shell script, which are handled by cron on tight intervals. Unfortunately, I keep getting empty emails each time the CRON has been executed and not only when things go wrong. Is it possible to only make CRON send emails when something goes wrong, ie. my TAR doesn't execute as intended? cron job email output Here's how my crontab is setup for the moment; 0 */2 * * * /bin/backup.sh 2>&1 | mail -s "Backup status" email@example.com Thanks a lot! bash shell cron schedule share|improve this question asked Jan 24 '11 at 9:40 Industrial 53921535 add a comment| 4 Answers 4 active oldest votes up vote 32 down vote accepted Ideally you'd want your backup script to output nothing if everything goes as expected and only produce output when something goes wrong. Then use the MAILTO environment variable to send any output generated by your script to your email address. MAILTO=email@example.com 0 */2 * * * /bin/backup.sh If your script normally produces output but you don't care about it in cron, just sent it to /dev/null and it'll email you only when something is written to stderr.

Sending mail is done by this setting in crontab: MAILTO=my@email.com I tried to run it with following command: * * * * * /path/to/script.sh > /dev/null 2 >> /path/to/file.log It emails the error all right. The log file is created but is empty. What am I doing wrong? ================================================================================== I found the solution. Thank you all for your help! (I cannot post it as an http://stackoverflow.com/questions/19451680/how-to-save-cronjob-error-to-file-and-email-it answer, so I am amending the solution here.) I used this reference How can I redirect stderr to a pipe? # version 2: redirect stderr to the pipe without getting stdout (it's # redirected to /dev/null) myprog 2>&1 >/dev/null | grep ... My solution is: #crontab MAILTO=my@email.com * * * * * /path/to/script.sh 2>&1 >/dev/null | tee -a /path/to/file.log Explanation: redirecting stderr to the pipe without getting stdout and then using tee -a for appending the stderr to the log file and printing it to the terminal, which is redirected automatically to email (see MAILTO). So I have a log file and email both containing the error message. linux crontab share|improve this question edited Oct 18 '13 at 18:12 asked Oct 18 '13 at 14:05 Petr 467 crontab needs the full path of the scripts to be executed.

The problem is that on debian derivates cron is logging to /var/log/syslog each time it executes.

Can I somehow only redirect a single cronjob to a separate log file? Preferably configurable inside
