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
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.
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.
