Getting Started with MariaDB

Using SHOW to list all databases on a server

To show a list of all of the databases on a server that the current user is allowed to see, use the SHOW DATABASES command as in the following example:

MariaDB [(none)]> SHOW DATABASES; 
+--------------------+ 
| Database           | 
+--------------------+ 
| dbt3_s001          | 
| flightstats        | 
| ham                | 
| information_schema | 
| isfdb              | 
| lds_scriptures     | 
| library            | 
| mysql              | 
| performance_schema | 
| test               | 
| wikidb             | 
+--------------------+ 
11 rows in set (0.00 sec) 

MariaDB [(none)]>

The preceding example is from my personal install of MariaDB; the databases listed when you run the command will almost assuredly be different. This command is useful especially if you're given access to an existing MariaDB ...
