Automate clear of mysql database in drush site install Is is possible to automate clearing the database when I run site install?
e.g. here is my drush command:

drush si geoslate --db-url='mysql://root:root@localhost/geo_test' --site-name=Geoslate


But the db has to be cleared first. Can I automate this process?
Chapabu is correct, but if you're using drush 5.7, this is unnecessary with site-install. If there's an existing db, drush will warn you it will drop all tables in the existing database.

For example:



drush dl drupal --drupal-project-rename=test
cd test
% drush site-install standard --db-url=mysql://root:root@127.0.0.1/test --site-name=test
You are about to create a sites/default/files directory and create a sites/default/settings.php file and DROP all tables in your 'test' database. Do you want to continue? (y/n): y
No tables to drop.                                                                          [ok]
Starting Drupal installation. This takes a few seconds ...                                  [ok]
Installation complete.  User name: admin  User password: 6SkT989sPX


So let's rerun the site-install command over the now existing "test" directory

% drush site-install standard --db-url=mysql://root:root@127.0.0.1/test --site-name=test         130 ↵
You are about to DROP all tables in your 'test' database. Do you want to continue? (y/n):
