SQL & PL/SQL

Friends,

DB: 11gR2

OS: Linux

I'm writing a shell script through which I pass schema name (OPS$USER) to the sql file to spool all objects of the user.

I'm not able to spool file with the '$' in the name, could somebody please suggest me if alternate options are available?

Since I'm using OPS$USER in the sql file as &1 I don't want to replace $ in the ksh script.

$SCHEMA = OPS$USER

$HOST = MAC

KSH:
$ORACLE_HOME/bin/sqlplus / @user_obj.sql $SCHEMA $HOST

SQL:
spool log.all_obj.&1.&2
SELECT count(*)
FROM dba_objects
WHERE username = &1;
exit;

Trying to create spool file with '$' sign in it or replace '$' with '_'.

i.e. log.all_obj.ops$user.mac or

log.all_obj.ops_user.mac

Many thanks.
