DB2 V8.2 FP12. Linux RH3

How can I schedule a db2cmd command via task schedular in the Control Center ?.

This is the command I want to execute in the command line but schedule it in task schedular:

Directory where the data file and the shell script resides (NightlyLoad.sh DataRefresh.txt):

Command: ./NightlyLoad.sh DataRefresh.txt MYSERVER REFRESHDB userid password

Thanks for any help.
