Passing value from plsql back to UNIX

Question

I have a shell script which calls out to a plsql program using sqlplus command, but how do I return the values from the plsql program (a simple SELECT statement) back to the Unix script? Thanks.

Create one UNIX script
eg :- C2_ATG_Insert.sh
#!/usr/bin/ksh
#Variables to store the values
count=0
Count_ILX_EXCH=0
Count_ILX_CBOE_SERIES=0
Count_ILX_UNDLY_INST=0
Count_STOCK_TIPS=0
Count_TIPSSUM=0
# Block to check whether date is passed as a parameter
if (($# != 1))
then
echo "Usage: C2_ATG_Insert.sh dd-mon-yy"
exit 1
fi
# Assign the trade date to a variable
Temp_Date=$1
# Call the sql, Count_Temp.sql with date as parameter
sqlplus usernam/password@Database_Name @Counts_Temp.sql $Temp_Date
# remove the blank lines
sed '/^$/d' Counts_Temp.lst > Counts_C2ATG.lst
# Store variables from the spooled file which gets generated in Count_Temp.sql into variables defined
while read myline
do
count=$(($count + 1))
case $count in
1) Count_ILX_EXCH=$myline ;;
2) Count_ILX_CBOE_SERIES=$myline ;;
3) Count_ILX_UNDLY_INST=$myline ;;
4) Count_STOCK_TIPS=$myline ;;
5) Count_TIPSSUM=$myline ;;
esac
done < Counts_C2ATG.lst
echo "ILX_EXCH Count $Count_ILX_EXCH"
echo "ILX_CBOE_SERIES Count $Count_ILX_CBOE_SERIES"
echo "LX_UNDLY_INST Count $Count_ILX_UNDLY_INST"
echo "STOCK_TIPS Count $Count_STOCK_TIPS"
echo "TIPSSUM Count $Count_TIPSSUM"
if [ $Count_ILX_EXCH -eq 0 ] || [ $Count_ILX_CBOE_SERIES -eq 0 ] || [ $Count_ILX_UNDLY_INST -eq 0 ] || [ $Count_STOCK_TIPS -eq 0 ] || [ $Count_TIPSSUM -eq 0 ]
then
     echo "*********** Count in one of the tables is Zero *****************"
     exit 1
fi
Create the SQL File eg Count_Temp.sql
SET heading off
SET VERIFY OFF
SET PAUSE OFF
SET ECHO OFF
SET TIMING OFF
spool Counts_Temp.lst;
select count(*) from ILX_EXCH where trade_date= '&&1'
UNION ALL
select count(*) from ILX_NONCBOE_SERIES where trade_date= '&&1'
UNION ALL
select count(*) from ILX_UNDLY_INST where trade_date = '&&1'
UNION ALL
select count(*) from STOCK_TIPS where trade_date = '&&1'
UNION ALL
select count(*) from TIPSSUM where trade_date ='&&1
spool off;
exit;
Do reply in case you are unable to undertand any part of the scripts
