My example.
Well, The thing is exactly that, I dont get it to return any data. The files have a structure where each line have a thread number and data after it:

2011-09-01 00:05:00,286 9220793 [Thread-17608] DATA DATA DATA.

I simply want the script to return in a line each instance of thread numbers through piping a cat command.

Code:
#!/usr/bin/perl
#2011-09-01 00:05:00,286 9220793 [Thread-17608]
my ($thread) = $_ =~ /\[Thread-\s*(.+?)\]/;
%seen = ();
@threads = ();

while (<STDIN>) {
        if ($_ =~ m/\[Thread-\s*(.+?)\]/) { unless ($seen{$thread}) {
        push (@threads, $thread);
        $seen{$thread}++;
        }}  else {
        $seen{$thread}++;
        }
}
        foreach (@threads) {
        print "$_";
        }

Any ideas?
