Hi harangzsolt33,

The problem you're experiencing does sound strange to me, especially with the behavior you describe here, but it's been a while since I worked with Perl on the command line in Windows - the explanations by the AM (here) seem plausible if you're trying to print lots of binary data.

I just wanted to point out that Perl has an operator that tries to tell "text" from "binary" files based on a heuristic: -T (the heuristic is described in the documentation).

Also, while walking a directory tree yourself is certainly a useful exercise, there are modules to help you, here's one example with Path::Class:

use warnings;
use strict;

use Path::Class qw/file dir/;

my $PATH = dir('.');

$PATH->recurse( callback => sub {
        my $file = shift;
        return if $file->is_dir || -B $file;
        my $fh = $file->open('<:raw') or return;
        read $fh, my $content, 2000 or return;
        close $fh;
        print $content;
    } );

Just a small note, in your current code you have a few variables that could have better scoping. $CONTENT could be defined right before its use in read, then you don't have to clear it every time. And the $SUB you define at the beginning of explore is actually never used because it is shadowed by the second $SUB in the while loop.

Hope this helps,
