Greetings all,

I have a question pertaining to File::Find, but more generally about callbacks.

How can I pass the $days_ago parameter into the callback function "&findNewerThan"? I seem to lose the value of File::Find::name when I pass in a parameter...

Eventually, I'll do a stat on the current file to get the modification time, and then accept or reject the filename

I'll also have other callback functions, some which accept parameters, and others that don't. I'll use a hash of coderefs for this

Thanks in advance for your help!

#!/usr/bin/perl -w

use strict;
use Data::Dumper;
use File::Find;

# Global array for the accumulated files...
my @files = ();

# Any directory will suffice here...
my $file_dir_root = "/var/log";

#------------------------------------------------
sub findNewerThan {
#------------------------------------------------
#  my $days_ago = shift;
  my $filename = $File::Find::name;
  return unless -f $filename;

# Now stat the file to compare its modification time
# with the days_ago parameter...

  push(@files, $filename);
}

#------------------------------------------------
sub days($) {
#------------------------------------------------
  my $days = shift;
  my $oneday = 60 * 60 * 24;
  return $days * $oneday;
}

#------------------------------------------------
#   MAIN
#------------------------------------------------
my $func = \&findNewerThan;

#find($func->(days(5)), ($file_dir_root) );
find($func, ($file_dir_root) );

print Dumper(\@files);
