Thanks for the reply.

If the extension of the files you want to use is ".txt", for example, you could do the following:

#!/usr/bin/perl
use strict;
use warnings;

my $folder = '/home/david/Programming/data';
foreach(glob "$folder/*.txt"){
    use_contents($_);
}

sub use_contents{
    my $filename = shift;
    print "$filename\n", '-' x 75, "\n";
    open my $fh, '<', $filename or die "Can't open $filename: $!";
    foreach(<$fh>){
        print;
    }
    print "\n", '-' x 75, "\n\n";
}

That's probably it. Try adding use File::Glob qw(bsd_glob); to the program.
