i wrote this code..

#!/bin/sh
sum=0
for i in `cat numbers.txt |cut -f1`
do
sum=expr $sum + $i
done
echo $sum


I want to read the numbers in the file numbers.txt. and find sum of them. But this code only writes the numbers(without making sum) that it reads. Help me..

burakkilic,

I normally use awk for this kind of problem - it works effectively

awk '{tot+=$1} END{print tot}' numbers.txt

Alternatively, change your script as shown:

#!/bin/sh
sum=0
for i in `cat numbers.txt |cut -f1`
do
sum=`expr $sum + $i` # Add back quotes around the expr
done
echo $sum

Thank you very much!.. The code is working properly
