Create a trigger file using touch

Hi,
I need to create a trigger file named "start" at 4 pm daily . Once this file is created , another process would be initiated. How do i do it using touch command in unix ?
My script that should have touch command shall be present in a dir /app/user/script while the trigger file should be generated in another dir /app/user/temp/ .

thanks.

man touch?

Have a read of the manual pages for the cron scheduler to get this done each day.

Let us know how you get on.
