( #3333=superdoc: print w/replies, xml ) Need Help??
When writing a fire-and-forget duplicates finder just now, I found this thread very useful. My coding style and approach seems rather different though. But whether low code granularity is good is often a highly debated issue.
sub dfind { my ($dref, $top) = @_; hidden( $top ) and return; if (-d $top) { for my $file (glob( "$top/*" )) { dfind( $dref, $file ); } } else { register( $dref, $top ); # add to HoA } } sub hidden { my $file = shift; my $attribs; Win32::File::GetAttributes($file, $attribs); return $attribs & HIDDEN; }
Update: note that hidden directories and files are both filtered out owing to how the recursion is contructed.

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.
