Change engine to all tables in a MySQL database

Here is a simple shell script to change the engine of all the tables in a MySQL database:

DBUSER=user
DBPWD=password
DBNAME=db
ENGINE=MyISAM
for t in `echo "show tables" | mysql -u$DBUSER -p$DBPWD --batch --skip-column-names $DBNAME`; do
    mysql -u$DBUSER -p$DBPWD $DBNAME -e "ALTER TABLE \`$t\` ENGINE = $ENGINE;";
done

Just because, as usual, I keep forgetting these kind of things…
