The problem is that those characters aren't literally back-slashed! What happens is that the backslash escapes the letter after it to become an escape character, so you're actually after these special escape characters. Something like this might be what you're after -
%ctrl_chars = ("\n" => '\n', "\t" => '\t', "\r" => '\r'); $line =~ s/$_/$ctrl_chars{$_}/ for (keys %ctrl_chars);
Of course you may want to replace other escape characters, in which case you'll probably want to check you the ascii table (see. man ascii(7).

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
