I have a FILE a.txt which has the following data

113901.94,113901.94,56950.97,56950.97,NOT MATCHING,NOT MATCHING
10693.04,10693.04,5346.52,5346.52,NOT MATCHING,NOT MATCHING
1901.94,1901.94,550.97,550.97,NOT MATCHING,NOT MATCHING
103.04,103.04,53.52,53.52,NOT MATCHING,NOT MATCHING

#### This IS my Code ####

RECIPIENT="xyz@mail.com"
FILE_PATH=/path/
cd $FILE_PATH
FILE=a.txt
chmod 777 $FILE

tgt_dr=`cat a.txt | awk -F',' '{print $1}' $FILE`
tgt_cr=`cat a.txt | awk -F',' '{print $2}' $FILE`

src_dr=`cat a.txt | awk -F',' '{print $3}' $FILE`
src_cr=`cat a.txt | awk -F',' '{print $4}' $FILE`

### Comparing for the Credit Amount

if [ -s $FILE ]
then

if [ $src_cr -eq $tgt_cr ]
then
exit 0
else
(echo "Hi All,


The sum of credit amount : $src_cr
The sum of credit amount : $tgt_cr


Thanks
user_name" )|mailx -s "`date '+%d-%m-%y'` Credit Amount" $RECIPIENT
fi
else
exit 0
fi

### Comparing for the Debit Amount

if [ -s $FILE ]
then
if [ $src_dr -eq $tgt_dr ]
then
exit 0
else
(echo "Hi All,

The sum of debit amount : $src_dr
The sum of debit amount : $tgt_dr


Thanks
User_name" )|mailx -s "`date '+%d-%m-%y'` Debit Amount" $RECIPIENT
fi
else
exit 0
fi

as of now my program handle only one row. pl let me know how to achieve this in looping if i have
multiple lines in the a.txt file

Thanks
