In the upcoming 5.14, you can do 
$var = ($var =~ s/\n//gr) =~ s/\s+//gr;

Note that for your particular case, 
$var =~ s/\s+//g;

[download]
will do, as newlines are whitespace.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
