Running Oracle Export Utility within a Shell script I have wasted a lot of time on this.  Any ideas of what I am doing wrong here?

Script in bash

#!/usr/bin/bash
.
.
.  

/export/home/app/oracle/product/10.2.0/bin/exp $uname/$passw \
    FILE="$WORKSPACE"/"$EXP_FILE" \
    LOG="$EXP_LOG" \
    TABLES=SYSTEM_PARAMETERS\
    CONSISTENT=Y \
    ROWS=Y \
    INDEXES=Y \
    CONSTRAINTS=Y \
    GRANTS=Y ;


Error Message

/export/home/app/oracle/admin/ukediuat/exp &gt;./exp_syspar.sh

LRM-00116: syntax error at 'TABLES' following '='

EXP-00019: failed to process parameters, type 'EXP HELP=Y' for help
EXP-00000: Export terminated unsuccessfully


Problem

The issue is with the dollar signs in the export command.  By replacing the variables which use the dollar sign with the full path the script runs.

Is there anyway to parse the shell variables into the export command?
Try changing the tables parameter to this. 
You only need parentheses when you have more than one table. 

TABLES='SYSTEM_PARAMETERS' \

$ exp tables=system.plan_table file=plan_table.dmp statistics=none
