Well, $/ is the input record separator; generally, in strings and patterns, \n is magically mapped to that behind the scenes – even if it consists of multiple characters on the platform in question, such as CR/LF on DOS.

Basically, using \n will always work so long as the data you’re processing comes from the same platform that you’re running on. If not, you’ll need to convert end-of-line markers. There’s no way to avoid this.

So outside specific scenarios, you should use \n or $/ and let Perl handle the specifics. That will also yield the most portable scripts.

Makeshifts last the longest.
