Creating pfile in RMAN script

Question

I am trying to create pfile from spfile from RMAN scripts as follows, but ran into issues
run {
2> sql 'create pfile=/tmp/p.ora from spfile';
3> }
sql statement: create pfile=/tmp/p.ora from spfile
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of sql command on default channel at 02/20/2009 11:23:06
RMAN-11003: failure during parse/execution of SQL statement: create pfile=/tmp/p.ora from spfile
ORA-02236: invalid file name
Any other suggestions to get the desired results. I want to create pfile in a different directory rather than defualt dbs directory.

Check your use of quotation marks.NO...read what you said.
What does SQL*Plus have to do with this command. You mentioned quotations marks...what kind of quotation marks..single or double and where should there be ??
