in reply to Chomp doesn't work

chomp strips from its parameter list the contents of $/, which is typically "\n". However, there are at least five Unicode code points that produce a newline (see perluniprops) Also, "\n" means different things on different machines; a file saved on a Windows system will have a different version of "\n" than a file saved on a Unix/Linux system. This could be getting in your way too.

    I got it. It's a little embarasing : each end of line has"\r\n" at the end. So by using this replace statement it works :

    $start_input =~ s/\r\n//d;

    So, if you ever get something similar, think about the "\r" before the "\n".

      Just use \R instead!
      $start_input =~ s/\r\n//d;

      /d is not a valid option for s///.    Perhaps you meant tr/\r\n//d?

        /d was added in 5.14.
