How do I kill all the processes in Mysql “show processlist”?

Question

Because I see a lot of processes there, and the \"time\" column shows big values for all of them.

#! /bin/bash
if [ $# != "1" ];then
    echo "Not enough arguments.";
    echo "Usage: killQueryByDB.sh ";
    exit;
fi;

DB=${1};
for i in `mysql -u  -h localhost ${DB} -p -e "show processlist" | sed 's/\(^[0-9]*\).*/\1/'`; do
    echo "Killing query ${i}";
    mysql -u  -h localhost ${DB} -p -e "kill query ${i}";
done;
