Yes, I would expect that. Cron only provides a minimal environment. In the case of the PATH,, it consists only of:


You need to use absolute paths for any commands not in the above or define you PATH list in your script. Any other environmental varaibles that you have defined in your login profile need to be defined too. The '.profile' sourced during normal logins is not handled for cron tasks.

See the 'crontab' manpages for more information.

Hi Jeeva,

Can you try calling script by creating file,


mv /myhome/
/usr/contrib/bin/gunzip /myhome/

# Crontab -e
30 18 * * * /pcard17/trace/


Problems are common to all, but attitude makes the difference

>I have given the absolute path for gzip command

That should fix it.
If you have other errors, add "set -x" to the script so you can see where it fails.

You may also change your find -exec to use "+" for performance:
-exec ls -ltr {} +

As a stylistic point, instead of passing info to your move function through the variable "a", you may want to pass it explicitly as a parm:
move $a
And inside of move, use "file=$1" and then use $file throughout.

Also, why use test instead of the shell builtin "[ ... ]"?
(And indentation helps. ;-)
