/usr/bin/mysqlctl

`mysqlctl` is a command-line client used for managing `mysqld` instances.

It is responsible for bootstrapping tasks such as generating a configuration file for `mysqld` and initializing the instance and its data directory.
The `mysqld_safe` watchdog is utilized when present.
This helps ensure that `mysqld` is automatically restarted after failures.

Usage:
  mysqlctl [command]

Available Commands:
  completion    Generate the autocompletion script for the specified shell
  help          Help about any command
  init          Initializes the directory structure and starts mysqld.
  init_config   Initializes the directory structure, creates my.cnf file, but does not start mysqld.
  position      Compute operations on replication positions
  reinit_config Reinitializes my.cnf file with new server_id.
  shutdown      Shuts down mysqld, without removing any files.
  start         Starts mysqld on an already 'init'-ed directory.
  teardown      Shuts mysqld down and removes the directory.
