It's not a problem with normal line-oriented use because the \n character is present on the end of every line with the possible exception of the last which then won't be empty. .... Try something like

Its not a problem at all as B::Deparse shows. The idea was for you to try it

$ perl -lE " open ARGV, q[<], \qq[0$/0$/0]; while ( my $line = <> ) { +say q[!!],!!($line) } say $. " !!1 !!1 !! 3
or
$ perl -e " print qq[0\n0\n0] " > 3zeros $ od -tacx1 3zeros 0000000 0 cr nl 0 cr nl 0 0 \r \n 0 \r \n 0 30 0d 0a 30 0d 0a 30 0000007 $ perl -le " while ( my $line = <> ) { 1 } print $. " 3zeros 3 $ perl -E " while ( my $line = <> ) { say q[!!],!!($line) } say $. " +3zeros !!1 !!1 !! 3

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 or How to display code and escape characters are good places to start.
