Could be written as
[ "${flag#!}" != "${flag}" ] && { success=1; flag=${flag#!}; }

> string=$( (( ${success} == 0 )) && echo ${string_success} || echo

if [ "${success}" = "0" ]; then
   string=${string_success}
else
   string=${string_failure}
fi
[ -n "${string}" ] && echo "${string}"

Thanks

Roy
