I want to read a file line-by line and write it line by line to another file.
Regarless of environment I want newline start with DOS's \x0d\x0a

Here's the code snippet:

$ii=open(MYHAN,"<file01.htm");
open(MYHAN2,">>receive.htm");
binmode(MYHAN);
binmode(MYHAN2);
while ($line=<MYHAN>)
{
chomp($line);
$line=~s/\x0d//g; # probably unnecessary
$line=~s/\x0a//g;
print MYHAN2 $rivi."testing\x0d\x0a";
}
close MYHAN;
closeMYHAN2;


The problem is that I get in "receive.txt" I get ending
"balhblahtesting[CR][CR][LF]" where [CR] mean carriage return and [LF] line feed.

Why is this happening? I've chomped and ~s'd the $line. I've also binmoded both
file handles for good measure.

close MYHAN2;

oops there was a typo - I had cut the code from another source but problem
remains teh same.

chomp() removes the value of $/ - i.e. LF on Unix, not CRLF.

I rewrote your code as follows and didn't get the error you mention on
either Ubuntu Linux or Windows or Cygwin:

#!/usr/bin/perl
use warnings;
use strict;
open(MYHAN,"<", "testcrs.pl") or die $!;
open(MYHAN2,">", "receive.txt") or die $!;
binmode(MYHAN);
binmode(MYHAN2);
while (my $line=<MYHAN>)
{
chomp($line);
$line=~s/\x0d//g; # probably unnecessary
$line=~s/\x0a//g;
print MYHAN2 $line." testing R\x0dS\x0aT";
}
close MYHAN;
close MYHAN2;

Note that the "binmode" is essential here - without that what you
describe is the expected behaviour on Windows. The most likely cause of
the problem is that "open (MYHAN2" ... actually failed and you were
looking at an old version of the file before you'd used the "binmode"
statement, or perhaps you didn't scroll down far enough (since originally
it was appending to receive.txt rather than overwriting it).

That can't be the solution, because he also used global substitutions to
remove any line feeds or carriage returns in the string $line.
