        return
    fi

    echo "Counting IPs"
    tail -f $log_file | egrep "${pattern:-.}" > $helper_file &
    sleep 60
    kill %1

    echo "-------------------------------------"

    awk '! /^-/ { print $1 }' $helper_file | tr -d , | sort | uniq -c | sort -k1,1nr -t. -k2,2n -k3,3n -k4,4n -k5,5n | head
