Your script is fine. Can you let us know how you are running it? As in, is the script an executable and are you running as: ./test.sh? Or are you running the script as: sh test.sh?

My guess is that it is the latter. In that case, the first line (#!/bin/bash) does not matter, and you are running the script using /bin/sh - which does not support $(( )).

Suggest that you follow fpmurphy's suggestion or make the script executable and run as ./test.sh

Thanks for ur valuable reply.........

TOTAL=`expr $e4 - $s4`
The above works fine..............
The error i did is i din leave space between the variables(i.e TOTAL=`expr $e4-$s4`)

Thanks
