Full Discussion: SED- Insert text at top of file

From the command line use
(Note that these must be completed on separate lines.)
This will insert on the first line of the file.

sed '1i\
your text goes here' file_name > new_filename


This will append on the last line of the file.
sed '$a\
your text goes here' file_name > new_filename


Note also that with sed you have to direct the output and rename the file back. So 'mv new_filename file_name' when you are done with these commands.

my_print_defaults

MY_PRINT_DEFAULTS(1)					       MySQL Database System					      MY_PRINT_DEFAULTS(1)

NAME

       my_print_defaults - display options from option files

SYNOPSIS

       my_print_defaults [options] option_group ...

DESCRIPTION

       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.

       o   --help, -?

	   Display a help message and exit.

       o   --config-file=file_name, --defaults-file=file_name, -c file_name

	   Read only the given option file.

       o   --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'.

       o   --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.

       o   --defaults-group-suffix=suffix, -g suffix

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

       o   --no-defaults, -n

	   Return an empty string.

       o   --verbose, -v

	   Verbose mode. Print more information about what the program does.

       o   --version, -V

	   Display version information and exit.
