Atomic String

When calling a loop, quote the variable otherwise bash will not see the string as atomic.

output_args()
{
  for arg
  do
    echo "$arg"
  done
}
var="hello Nico"

echo "Without Quotes"
echo "**************"
output_args $var
echo 
echo "With Quotes"
echo "**************"
output_args "$var"

Without Quotes
**************
hello
Nico

With Quotes
**************
hello Nico
