There are many utilities and it is not always easy to remember all of the options and parameters associated with each. Sometimes we need to run several utilities using nearly the same options. For example, you may want to run several utilities logging into a particular server. Rather than retype the connection information each time, you would like to save the option value some way and reuse it.
Fortunately, the mysqluc utility does this and more. It is named the MySQL Users' Console and provides type completion for options, utility names, and even user-defined variables for working with common option values. Not only that, it also provides the ability to get help for any utility supported.
