Sometimes all you want to do is run a big script or import a database using the MySQL command line tool without echoing out tons of output.  Luckily it's dead easy.  If the script you want to run is called script.sql just ssh into your machine and type:

mysql -uUSERNAME -pPASSWORD DB_SCHEMA < script.sql

Substituting your username and password and the database you want to run the script against.
