Replace $_ =~ s/\s/\|/g; with local $"='|';.

$" sets the delimiter between array elements in a double quoted string. By default, it is set to a single space which is why you were originally seeing a space between array elements. The space wasn't part of the array elements, nor the array, which is why trying to substitute spaces with pipes didn't work.

$" is a global variable. The keyword local keeps your custom setting of that variable from affecting other parts of your code. Your custom setting will only apply within the while loop.
