What I generally do is
exec 0>3
exec 1>4
exec 2>5
ks_con_Out() {
echo "address@hidden" >&4
}
that way stdout is only for return values.
if all you want o do is return value in bash then its better to use the
folloing approach
# Arg 1 value to set with return value
func_sample() {
printf -v "${1}" "%s" "Return Value"
}
