Re^2: Newbie: uses/limits of perl in editing files

[naikonta]

Caveat: Both of these are for systems where the line ending is "\n" (i.e. not Windows), adjust appropriately for other OSes.

I see no caveat in your example regarding \n. This character is just the Perl internal representative of a thing that constitutes line ending. So it will be whatever the underlying OSes (perl is run on) actually use to terminate lines. See how newlines are addressed in perlport.
