MySQL kill all queries by user

Here’s a dirty command-line utility that kills all MySQL queries originated by a given user:

mysql -u'YOUR_MYSQL_USER' -p'YOUR_MYSQL_PASSWORD' -h'YOUR_MYSQL_HOST' -e "select ID from information_schema.processlist where user='YOUR_MYSQL_USER';" | sed '1d' | awk '{print "kill ", $1, ";"}' | xargs -i mysql -u'YOUR_MYSQL_USER' -p'YOUR_MYSQL_PASSWORD' -h'YOUR_MYSQL_HOST' -e "{}"
