Syntax for option key down to empty trash.

Does anyone know the syntax for emptying the trash with the option key down.
I have a script that contains empty trash, but it will not empty the trash because a file in the trash has been locked. The trash will empty with the option key down, but I can not figure out how to write this.

Jack, take a look at this thread…
