I'm trying to add multiple numbers with varying length and with leading zeroes in it. However, I'm getting the sum (totalHashAccountNumber) without the leading zeroes in it. How do I retain the leading zeroes?
Please pardon the lengthy code.. I'm getting the hash account number from 2 different fields and do translation when there are non-numeric characters in the account numbers.
Code:
#---------------------------------------------------------------#
# compute for the total hash account number #
#---------------------------------------------------------------#
typeset -i totalHashAccountNumber=0
while read line
do
#rec_type=$(expr substr "$line" 1 1)
rec_type=`echo "$line" | cut -c1-1`
if [[ "$rec_type" == 'P' ]]; then
#IBAN=$(expr substr "$line" 1021 34)
IBAN=`echo "$line" | cut -c1021-1054`
if [[ "$IBAN" == '' ]]; then
#accntNum=$(expr substr "$line" 268 18)
accntNum=`echo "$line" | cut -c268-285`
hashAccountNum=$accntNum
else
hashAccountNum=$IBAN
fi # end - if IBAN is null
# check if hashAccountNum is all numeric
if [[ $hashAccountNum == +([0-9]) ]]; then
totalHashAccountNumber=$totalHashAccountNumber+$hashAccountNum
else # translate non-numeric characters from hashAccountNum
tempHashAmt=`echo $hashAccountNum | tr 'AKUBLVCMWDNXEOYFPZGQHRISJT' '00011122233344455566778899'`
if [[ $tempHashAmt == +([0-9]) ]]; then
totalHashAccountNumber=$totalHashAccountNumber+$tempHashAmt
else
i=1
tempHash=""
while (( i <= ${#tempHashAmt} ))
do
char=$(expr substr "$tempHashAmt" $i 1)
case "$char" in
[0-9] ) ;;
* ) char="0"
esac
hashNum=$tempHash$char
tempHash=$hashNum
echo "tempHash: "$tempHash
(( i += 1 ))
done
totalHashAccountNumber=$totalHashAccountNumber+$tempHash
fi # end - second check if numeric
fi # end - hashAccountNum is numeric
fi # end - get rec_type
done < $stagedir/$1
The length of totalhashAccountNumber may vary, at times, there are no leading zeroes in it.
I should have added this to my original post. The reason why I wanted the leading zeroes retained from the totalHashAccountNumber is that I will only need the first 10 digits from it. So from 07771636492, my final ouput will be 0777163649.
Hi,
