CRON/crontab does not log errors?

  • 772

Is there a way to see if there are any errors when crontab job is executed?

I purposely added a command that returns error so I can check if I'm able to see the error.

*/1 * * * * cd /home/dirthatdoesnotexist && echo "RUNNING" > /tmp/cronlog.log 2>&1

When I call it manually:

milano@milano-desktop:~$ cd /home/dirthatdoesnotexist && echo "RUNNING"
bash: cd: /home/dirthatdoesnotexist: No such file or directory

It returns error as the directory doesn't exist.

But I can't see the error when it's called by CRON.

I checked /tmp/cronlog.log which does not exist. I also checked /var/log/syslog which says that the command has been executed, but it doesn't show the error.

milano@milano-desktop:~$ tail /var/log/syslog

Dec  7 20:12:01 milano-desktop CRON[64935]: (CRON) info (No MTA installed, discarding output)

Is there a place where the error is logged?

bash
