mysqld: Print the default arguments and their values and exit.

mysqld

$ mysqld --print-defaults

try on your machine

The command mysqld --print-defaults is used to display the default values and other configuration options for the MySQL server (mysqld).

When you run this command, MySQL will retrieve the default values for the server configuration from the configuration files (my.cnf or other relevant files) and display them in the terminal. These default values usually include various settings such as database directories, network settings, log file paths, memory configurations, and more.

This command can be useful when you want to check the default configuration values that MySQL server will use when started. It is especially helpful if you have modified the configuration files and want to make sure the changes are effective. By printing the default values, you can compare them with the modified settings to ensure your configuration changes are working as expected.
