I just tried to do it your way, but had no success. Instead i tried writing it like below, but now i am stuck with the fact that i get the error 'No such file or directory' and the code doesn't run with taint!
#! /usr/bin/perl
my $directory = '/var/log/cr_user/';
opendir DIR, $directory or die $!.$/;
my @files = readdir(DIR);
closedir DIR or warn $!.$/;
for my $file (@files) {
open FILE, $file or die $!.$/;
my ( $username, $domain, $email, $service ) = split /,/, <FILE>;
print "$username";
close FILE or warn $!.$/;
unlink $file;
}
