Thank you for the information, GrandFather, I did not know a conversion was done during I/O, I thought that it was chomp that was clever enough to remove "\n" or "\r\n" depending on whether the script was running on Unix or Windows, for example.

We regularly have issues at work in a different type of situation, when we process files generated by another application running on another system, with end of lines sometimes converted and sometimes not converted during the transfer (FTP in ASCII or bin mode, SFTP, scp, etc.). We then need to pre-process the file before feeding them to our programs (in some cases we even have changed our programs so that they can handle smoothly both cases).
