How about you explicitly tack an explicit

    exit;

onto the end of the input?

    % mysql -u concerts -h localhost -p concerts
    Enter password: 
    Welcome to the MySQL monitor.  Commands end with ; or \g.
    Your MySQL connection id is 440197 to server version: 3.23.41-log

    Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

    mysql> exit;
    Bye
