Depending upon the OS your Perl script is running under,

Since the meaning of that "match" is a bit ambiguous to me, let me be
maybe a bit redundant to be sure the OP gets this right and clear:
length "\n" is == 1 always. Everywhere. No matter the OS newline
convention. "\n" is eq "\012" in all supported platforms except in
MacPerl (pre-OSX), where it is eq "\015".
In text mode the I/O subsytem is responsible of transforming native
newlines up to "\n" while reading, and "\n" down to native newlines
while writing. That is transparent to the programmer but is the key
to understand problems when line-oriented programs deal with text
that does not follow the conventions of the runtime platform.
