Hi, I need a help with renaming files which begins "sniffer" in directory. 
opendir(DIR, '.') || die "Couldn't opendir: $!\n";

foreach my $filename (reverse((grep /^sniffer/, readdir(DIR)))) 
{
    my $new_name = $filename;    
    if($new_name =~ m/(\d+)/)
    {
        my $value = $1 +1;        
        $new_name =~ s/.*/"sniffer$value\.log"/;          
    }
    else
    {
        $new_name =~ s/.*/sniffer1.log/;
    }
    rename($filename, $new_name) unless $filename eq $new_name;    
    close(DIR);

My aim is to increment number in files which begin "sniffer". In example: sniffer.log will be sniffer1.log, sniffer1.log will be sniffer2.log, etc. The oldest file (with the highest number) must be changed at the beginning - this is the reason of using reverse function in foreach loop.

Unfortunately I received this error: 

Insecure dependency in rename while running with -T switch at ...

If anyone knows the solution of this problem or the easiest way how to increment files number ?

Thanks in advance ;)
