printf "Flushed tables ($hc_tables) in %d seconds.\n", time-$start unless
$opt{quiet};
fix :
printf "Flushed tables (%s) in %d seconds.\n", $hc_tables , time-$start unless
$opt{quiet};
also here better use %s for $0 :
printf "$0 copied %d tables (%d files) in %d second%s (%d seconds overall).\n",
$num_tables, $num_files,
$hc_dur, ($hc_dur==1)?"":"s", time - $start_time
unless $opt{quiet};
