Bash

It seems Bash doesn't like spaces with assignments using declare.


--- Code: Bash ---# bash - 1mil.sh declare -i accum=0declare -i milvar=1000000 for i in {1..1000000}do  ((++accum))  ((--milvar))  if (( $accum == $milvar ));    then      echo "Middle"  fidone echo "Plus:  " $accumecho "Minus: " $milvar
