Следующий код увеличивает значение summ,
но после выхода из цикла там опять ноль ??

Как с этим бороться?
export summ -- не помогает.

==================================
summ=0
cut $LOG_PATH/jur-traffic.log -d" " -f5 | (
  while read var;
  do
     summ=`expr $summ + $var`;
     echo "---------------------- $summ";
  done
)
echo "---------------------- $summ";
==================================
