Do not forget that cron does not use the root environment, such as $PATH. You need to set up the exect environment you need in the beginning of the crontab file. It would be helpful to see your crontab file to know what environment it has set up.
Also the /var/log/cron log file should contain error information that might be helpful.

Hi
I have a script to resign all DNS zones every two weeks. When i run the script from bash, it works like it should. But when it is executed in cron not. Its starting normal as cronjob: Feb 1 03:00:01 xxx CROND[20116]: (root) CMD (sh /opt/dnssec/resign_dnssec_zones.sh)
But after i get a mail that everything is finsihed, but it isn't. 03:04:28 DNSSEC-Signierung abgeschlossen
The script deletes the old signed zones, but don't resign it. The mail is also sent. Below the script.
Anybody an idea why it doesn't work in cron?^ I cannot find any error in any log.
After the first line, add a line saying: set -x
Then set cron to run it and examine the output that gets mailed to you.
The -x tells it to echo each command it is about to execute. That will help you to see how far it is getting.
Further comments below.
Cheers Tony
Best regards Daniel

Why not just: ZONE=${FILES%.*}

You deleted them all further up.
#Sign the zone cd $ZONEDIR
Why not do this before the loop? Then you also don't need $ZONEDIR/ everywhere.
