Re^3: Using map to Add a Line Breaks to a List

in thread Using map to Add a Line Breaks to a List

It's due to the capturing regex in list context. This returns a list of captured strings. Map then passes this list and the "\n" to print. Since $, = $\ = "", your output works the way it does. Of course, this will print blank lines if your filename doesn't contain a period.
