welcome to WebmasterWorld, prakash!

type "crontab -e" to edit (add cron commands to) your existing cron table.
or type "crontab /path/to/file" to install commands from an existing file to your cron table.

the column format of cron commands is:
minute hour mday month wday command

a "*" in a column means run the command every occurrence of that period.

Welcome Prakash!

It's hard to give precise instructions without knowing all the details. In any case with something like crontab you will want to learn enough to be able to fix issues that might occur. The easiest way to get at the syntax is to type:

man 5 crontab

Remember to use absolute paths in crontab as your .bashrc file is not loaded.
