mysql --table -e "
SELECT TABLE_SCHEMA AS 'database',
SUM(INDEX_LENGTH) AS 'used index',
SUM(DATA_LENGTH) AS 'used data',
SUM(MAX_DATA_LENGTH) AS 'max data'
FROM INFORMATION_SCHEMA.TABLES GROUP BY TABLE_SCHEMA"


however the maximum size will often be arbitrary. Or it may read 0 when
the engine does not have per table limits.
