.SH "DESCRIPTION"
.PP
\fBmy_print_defaults\fR
displays the options that are present in option groups of option files\&. The output indicates what options are used by programs that read the specified option groups\&. For example, the
\fBmysqlcheck\fR
program reads the
[mysqlcheck]
and
[client]
option groups\&. To see what options are present in those groups in the standard option files, invoke
\fBmy_print_defaults\fR
like this:
.sp
.if n \{\
.RS 4

.nf
$> \fBmy_print_defaults mysqlcheck client\fR
\-\-user=myusername
\-\-password=\fIpassword\fR
\-\-host=localhost
.fi

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