       my_print_defaults - display options from option files

SYNOPSIS         top

       my_print_defaults [options] option_group ...

DESCRIPTION         top

       my_print_defaults displays the options that are present in option
       groups of option files. The output indicates what options will be
       used by programs that read the specified option groups. For
       example, the mysqlcheck program reads the [mysqlcheck] and
       [client] option groups. To see what options are present in those
       groups in the standard option files, invoke my_print_defaults
       like this:

           shell> my_print_defaults mysqlcheck client

       The output consists of options, one per line, in the form that
       they would be specified on the command line.

       my_print_defaults supports the following options.

       •   --help, -?

           Display a help message and exit.

       •    --defaults-file=file_name, -c file_name

           Read only the given option file. If no extension is given,
           default extension(.ini or .cnf) will be used. If
           --defaults-file is the first option, then read this file
           only, do not read global or per-user config files; should be
           the first option.

       •   --debug=debug_options, -# debug_options

           Write a debugging log. A typical debug_options string is
           ´d:t:o,file_name´. The default is

       •   --defaults-extra-file=file_name, -e file_name

           Read this option file after the global option file but (on
           Unix) before the user option file. Should be the first

       •   --defaults-group-suffix=suffix, -g suffix

           In addition to the groups named on the command line, read
           groups that have the given suffix.

       •   --mysqld

           Read the same set of groups that the mysqld binary does.

       •   --no-defaults, -n

           Return an empty string (useful for scripts).

       •   --verbose, -v

           Verbose mode. Print more information about what the program

       •   --version, -V

           Display version information and exit.
