You may want to try globbing to build your list.

use File::Glob qw(:globally :nocase); chdir 'd:\log\exported'; my @files = <*.elog>;
Alternatively, if you want to do processing on each file in the list, File::Find will also work for you and would give you a little more control over which files make it into the list.

    I thought I'd take a quick break from work and see if I could write the File::Find version of this. The following code will create a list of the files modified in the past seven days in d:\log\exported. I didn't backdate the files in my directory to test this thoroughly, but it seems to work.
    use File::Find; my $ageLimit = 7; # the age (in days) of the oldest file you want to +process my $ageCutoff = time - $ageLimit * (60*60*24); # the cutoff time my @logFiles = (); my $findFilter = sub { if ( (stat($_))[9] > $ageCutoff ) { # only push files newer than c +utoff push @logFiles, $_; } return; }; find($findFilter, 'd:\log\exported'); # populates the list

      Dont forget File::Find is recursive. So youll grab all the files that match in sub directories as well, and should it contain a directory thats new enough you'll have a problem as it'll get included as well. Also as you are simply pushing the base name into the list you wont even know whats happening until you start to diagnose missing files and find them two layers deeper in the file structure :-)

      use File::Find; my @files; my $age_limit=7; find { wanted=>sub { -f and -M($_) < $age_limit and push @files, $_ }, no_chdir=>1 }, 'd:\log\exported'; print join("\n",@files),"\n";

      You should take a look at find2perl
