V$session and v$sqlarea is interpreting in different way

Question

I am using redhad linux 5 version. The db version is oracle11g.
I am trying to run the below shell script on the linux box
export ORACLE_SID=chf01
export ORACLE_HOME=/ora/app/oracle/product/11.1.0/db_1
export WORKDIR=/ora/app/oracle/admin/chf01/scripts
cd $WORKDIR
$ORACLE_HOME/bin/sqlplus scott/tiger@ch01 << EOF
spool sqlcapture.log
INSERT INTO scott.T_SQL_CAPTURE
SELECT MACHINE,
SQL_FULLTEXT
FROM
v$session a,
v$sqlarea b
where
((a.sql_address = b.address
and a.sql_hash_value = b.hash_value )
or ( a.prev_sql_addr = b.address
and a.prev_hash_value = b.hash_value))
commit;
spool off
exit
EOF
ERROR=`grep 'ORA-' sqlcapture.log | wc -l`
if [ "$ERROR" -gt 0 ]
then
cat sqlcapture.log|mailx -s "sqlcapture is failed" \ [email protected]
else
cat sqlcapture.log|mailx -s "sqlcapture is successful" \ [email protected]
fi
exit
here is the spool file content. v$session is interpreted as v a and v$sqlarea is interpreted as v b.
How can i fix this?

11 and a.prev_hash_value = b.hash_value))
13 ;
v b

Because *$* is interpreted by Linux shell. So you need to escape it. I used to escape all $ with \$ but someone in another thread posted a lovely trick. Use this:
$ORACLE_HOME/bin/sqlplus scott/tiger@ch01 << \EOF
.
