( [id://3333] : superdoc . print w/replies, xml ) Need Help??
In addition to the other comments above, I would like to make the following two small additional comments:

  1. There is a great potential for an endless recursive loop to be established if your program processes a symbolic link to a directory higher in the directory tree - This is a common trap that File::Find-like subroutines get caught by. To correct this, simply add a negative test for symbolic link with your -d test. ie.

    if (-d $dir && !-l _) { ... };
  2. And less importantly, the sort by_lc readdir(DIR) block in the op_dir subroutine could more easily be written as thus:

    foreach (sort { lc($a) cmp lc($b) } readdir(DIR)) { push (@dir, "$dir\/$_") if (m/$non_include/); };


Ooohhh, Rob no beer function well without!

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.
