Hi
I have this script

#!/bin/bash
cat status.txt | while read LINE
do
linija="$LINE"
echo $linija
echo $linija | awk '{print $1}' > temp.txt
koj=`tail -1 temp.txt`
echo $koj
echo $linija | awk '{print $2}' > temp1.txt
kolku=`tail -1 temp1.txt`
vkupno=$(( vkupno + kolku ))
echo $kolku
echo $vkupno > vkupno_temp.txt
done
kolku_vkupno=`tail -1 vkupno_temp.txt`
echo $kolku_vkupno

and its working perfectly in 2.05b.0(1) bash called with ksh and bash
But in 3.2.25(1) version of bash only the first line of status.txt passes. Then (on the second line of the file status.txt) i get this error : arithmetic syntax error
on this line vkupno=$(( vkupno + kolku )). Can someone pls help. What should i change in the script to work in new bash.

Thanks in advance

P.S. status.txt consists of lines :
sometext 4
another text 12
and so on
