Basic MySQL Command Line Usage on Ubuntu 22.04

Using a MySQL server by a CLI can be somewhat daunting at first, but it is really quite useful! Here's some basic commands to get started.

System CLI vs. MySQL CLI

To log access the MySQL CLI enter the following command in your system CLI:

mysql -u root -p

Where "root" is the user you want to log into the server (the string after the -u flag indicates the user). After you have created other users, you can log in using the same method with those other users. The -p flag will prompt you for the password for that user in the command line after pressing enter.

After entering the password for the MySQL user in the command prompt, your CLI prompt will change from something like:




To exit the MySQL command line and return to the system CLI, simply type exit; and press enter:

mysql> exit;

Listing All MySQL Databases

Once logged into the MySQL CLI, show / list all of the databases on the server by entering the following (including the semi-colon):


Which should output in your terminal a one-column table like:

| Database           |
| information_schema |
| mysql              |
3 rows in set (0.00 sec)
