Delete MySQL Database with mysqladmin

mysqladmin is a MySQL built-in command-line utility that allows you to create and delete MySQL databases, check MySQL processes, and set a MySQL root password via a command-line interface.

First, use the following command to list all available databases in your system:

| information_schema |
| magentodb          |
| mysql              |
| performance_schema |
| sys                |
| wpdb               |
+--------------------+

Now, pick the drupaldb database from the above list and delete it by running the following command:

mysqladmin -u root -p drop drupaldb

You should see the following output:
