I'm trying to do periodic scans for new files in a single directory and process them with a subroutine.
I've written some code, shown below, but it will only process the subroutine once.

I've got two questions for the Monastery:

  1. Why does the subroutine only execute once? I'd like it to run every 30 seconds, hence the do ... while(sleep(30)).
  2. Does anyone have any suggestions on how to modify this script (once working) to process only the new files?

As always, thanks very much. 

  #!/usr/bin/perl -w

  use strict;

  my $dir = "/home/dhaffner/src/codemonkey/test";
  opendir (DIR,$dir) or die "That's all folks!";
  {
       do {
      my @files = grep { -f "$dir/$_" } readdir(DIR);
      foreach my $file (@files) {
          GoProcess ($file);
      }
      } while (sleep(30))
  }
  closedir (DIR);

  sub GoProcess {
      print "I can process $_[0] for you now.\n";
  }
