Try this :

mysql -uuser -ppassword -e 'show processlist' | grep USER_NAME | awk {'print "kill "$1";"'}| mysql -uuser -ppassword

The command will list the processes running in the database and return a kill 'query id'; command and pipe it into mysql again.
Be carefull with this command as there is no rollback form it :)

  • When piping back to mysql, use --force, since a KILL command will fail if by change the connection has already terminated. Without --force this will abort all following KILL commands. Mar 22, 2014 at 20:20

You may also use common_schema's kilall() procedure from within your MySQL server. Use:

call killall('evil_user');
