perl - newlines when displayed in Windows - 


open out, ">output.txt"; print out "hello\nworld";

when run above perl code in unix system , transfer output.txt windows , open in notepad shows as:

helloworld

what need newlines displaying in windows?

text file line endings platform-specific. if you're creating file intended windows platform should use

open out, '>:crlf', 'output.txt' or die $!;

then can just

print out "hello\nworld!\n";

as normal

the :crlf perlio layer default perl executables built windows, don't need add code create files intended platform. portable software can check host system examining built-in variable $^o
