( #3333=superdoc: print w/replies, xml ) Need Help??
Hi Dave. I will post what Ive done so far it might be useful. Certainly the tests I am having are showing some really good speed advantages in Linux anyways. As per most of my software works in the past, this is done for love, not for monetary gain and the only thing I would say is for any future user to take absolute care when using it as Ive been programming in Perl for only 3 days and there are bound to be some errors. Davo, your info has been extremely helpful and you pointers taken. I had just been checking the recursive module and it calls File::Copy::copy I did try to hook into that waste of time, yours works, but it seems to be far too re-entrant so I get about 10 x the number of files and directories as a result in dircopy(), more accurate on pathrm() The code below is still under testing, so user beware and there are some extra print statements and tests so its not ready for user. Any tips appreciated.

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).
