Hello,
I got simple bash script which is running through crontab as user 'root'
#!/bin/bash
#echo $CacheIP
CurreIP=$(wget http://freedns.afraid.org/xxxxxx-something to catche my current ip adderess
if [ "$CurreIP" = "$CacheIP" ]
then
echo Both IP are equal
echo "Update not required..."
else
wget http://freedns.afraid.org/dynamic/update.php something to update my current ip adderess

#Here is the problem
echo "$(date) Updating log with IP $CurreIP " >> dnsactual.log

fi
rm -f /etc/freedns/dnsactual.conf
echo $CurreIP > /etc/freedns/dnsactual.conf


when I am running this script manually it is work perfect(meening I got dnsactual.log start filling), but doing it through crontab it is do the job concerning update my ip address like it is suppouse to do, but I do not have dnsactual.log file updated

Well, maybe you don't have it in the place you expect it to be. A cron job run from the user home directory by default, so that every relative path inside the script is relative to $HOME. Check if $HOME/dnsactual.log has been created. As a general rule, it's safer to use absolute paths for both the commands and the files inside the cron job.

Excellent, working like a charm, I did not know about ($HOME by crontab)
Actually all my logs after running this script by cron, were in my /root/dnsactual.log directory
Thank a lot for the hint
