The default environment for cron is quite limited.
Try making a one-off cron to enquire what the environment is like. In your case the current working directory was not your home directory.

Code:
echo "Current working directory"
pwd
echo "Environment variables"
env

Hi,

I executed the cron job from home directory.

Cron is also in the home directory.

Yes, I defined the current directory in my cron file and as well as for the tar also.

But, what I don’t understand is that, when I am executing the Croncript.ksh directly I am getting the desired result. While doing the same with the help of cron I am not getting the desired result !

The cron job fails to tar and gzip the test.log file

Please have a look to the above post which I quoted from the mail message !
Code:
/other/file/at/the/user/side/testBackup.log.tar: No such file or directory
chmod: CronScript.ksh: No such file or directory

you must define the full path in your script within as cronjobs
