my_print_defaults — display options from option files
my_print_defaults [options] option_group ...
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 --user=myusername --password=secret --host=localhost
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.
Display a help message and exit.
--config-file=file_name, --defaults-file=file_name, -c file_name
Read only the given option file.
--debug=debug_options, -# debug_options
Write a debugging log. A typical debug_options string is d:t:o,file_name. The default is d:t:o,/tmp/my_print_defaults.trace.
--defaults-extra-file=file_name, --extra-file=file_name, -e file_name
Read this option file after the global option file but (on Unix) before the user option file.
--defaults-group-suffix=suffix, -g suffix
In addition to the groups named on the command line, read groups that have the given suffix.
--login-path=name, -l name
Read options from the named login path in the .mylogin.cnf login path file. A “login path” is an option group containing options that specify which MySQL server to connect to and which account to authenticate as. To create or modify a login path file, use the mysql_config_editor utility. See mysql_config_editor(1).
Return an empty string.
As of MySQL 5.7.8, my_print_defaults masks passwords by default. Use this option to display passwords in cleartext.
Verbose mode. Print more information about what the program does.
Display version information and exit.
