Add date to backup controlfile to trace command

Question

A little background:
I'm writting a rman script and want to include a controlfile to trace and a pfile.
The commands I'm using are:
alter database backup controlfile to trace as 'd:\oracle\backup\controlfile.bak';
create pfile='d:\oracle\backup\pfile.bak' from spfile;
However, I want the file to be controlfile.bak.theDate, ie controlfile.bak.20090323, as I want to keep so many days worth and not overwrite the file.
How can I add the date in this way?
Thanks in advance.

But why do you want to do so when RMAN itself can take the controlfile backup and of the pfile automatically.Why do want to get the trace of controlfile.In you script simply add
backup current controlfile format '/location/ctl_%d_%T';
backup spfile format 'location/sp_%d_%T';
%d ---> The name of the database.
%T ---> The year, month, and day (YYYYMMDD)
Every time you take a backup, the controlfile and spfile with unique name will be present along with the database backup.
