mysqld: Start the server, reading arguments and values from a file.

mysqld

$ mysqld --defaults-file=${filename}

try on your machine

This command is used to start the MySQL server with a specific configuration file. Here's a breakdown of the command:

mysqld: This is the command to start the MySQL server daemon (mysqld).
--defaults-file=${filename}: This option specifies the path to the MySQL server configuration file. The ${filename} is a placeholder that needs to be replaced with the actual file name and path of the configuration file.

By default, the MySQL server reads the configuration from the default location (/etc/my.cnf or /etc/mysql/my.cnf, depending on the system). However, using this command, you can explicitly specify a different configuration file to be used for configuring the server.

For example, if you have a configuration file called mycustom.cnf located in the /etc/mysql/ directory, you can use the following command to start the MySQL server:

mysqld --defaults-file=/etc/mysql/mycustom.cnf

This command will start the MySQL server with the configuration settings defined in the mycustom.cnf file instead of the default configuration file.
