Anything about cron in the system logs, or in e-Mail to the owner of that cron-tab entry?

Do you have a blank line between your command and the end of the crontab? I've noticed before on my systems that if there isn't a blank line after the last cron entry, it won't run.

crontab entries run in a special environment, so maybe sh and env cannot be evaluated. Check PATH variable, or try to use full path:

Code:
00 08 * * * /usr/bin/sh /scripts/Shrink_MSM_ROM_RAT.sh > /scripts/Shrink_MSM.log

Code:
/scripts/Shrink_MSM_ROM_RAT.sh
Is that the full path to the script you are trying to run? Are there any relative paths or variables in the script itself which would make sense when you manually run the script but not so much when the script is run by cron? I have found in the past when a job like this fails it is because the script runs OK under my login but it contains shortcuts or variables which are specific to my login and are not available to cron

I have had to change working directory on stuff like this before. This may help it may be redundant. I would also capture error stream with 2>&1.

00 08 * * * cd /scripts && /usr/bin/sh Shrink_MSM_ROM_RAT.sh > Shrink_MSM.log 2>&1

Hi Kai,

I'm having the same issue. Would appreciate if you post a sample entry of before and after you got it working.

Thanks!
