Hmmm, File::Find is really for delving into the subdirs,

I know, and it's difficult to grok sometimes how to use it correctly - the whole "prune/not prune" thing is still unclear to me. But besides that...

and if you don't want that, then just glob(*) like this:

For a while now I've been pondering which was faster, a glob or a readdir, so I decided to test it on a big directory I've got lying around (36K files).

The answer?

glob failed (child exited with status 1) at line 12.

Nuts. Do I recall somewhere that Perl relies on the shell for globbing in some way? If so, going with a readdir on a big directory may be your only choice.

As for speed issues, you have to loop over everyfile, no matter what,

And, although I can't speak for NTFS/HPFS/FAT filesystems, I know that a flat directory on Solaris or Linux is going to be a serious dog to scan over 1000 files, no matter what.

Implement a heirarchical subdirectory scheme - maybe based on the date, which would simplify purging, too.

That's what I did, faced with a similar problem, anyway. :-)

Use:  <p> text here (a paragraph) </p>

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.
