You should output the results to some file. Only then can you see the changes.
Code:
sed -e 's/ *$//g' file_name > file_name.temp
mv file_name.temp file_name

comp_err

COMP_ERR(1)						       MySQL Database System						       COMP_ERR(1)

NAME

       comp_err - compile MySQL error message file

SYNOPSIS

       comp_err [options]

DESCRIPTION

       comp_err creates the errmsg.sys file that is used by mysqld to determine the error messages to display for different error codes.  comp_err
       normally is run automatically when MySQL is built. It compiles the errmsg.sys file from the plaintext file located at sql/share/errmsg.txt
       in MySQL source distributions.

       comp_err also generates mysqld_error.h, mysqld_ername.h, and sql_state.h header files.

       For more information about how error messages are defined, see the MySQL Internals Manual[1].

       Invoke comp_err like this:

	   shell> comp_err [options]

       comp_err supports the following options.

       o   --help, -?

	   Display a help message and exit.

       o   --charset=path, -C path

	   The character set directory. The default is ../sql/share/charsets.

       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/comp_err.trace.

       o   --debug-info, -T

	   Print some debugging information when the program exits.

       o   --header_file=file_name, -H file_name

	   The name of the error header file. The default is mysqld_error.h.

       o   --in_file=file_name, -F file_name

	   The name of the input file. The default is ../sql/share/errmsg.txt.

       o   --name_file=file_name, -N file_name

	   The name of the error name file. The default is mysqld_ername.h.

       o   --out_dir=path, -D path

	   The name of the output base directory. The default is ../sql/share/.

       o   --out_file=file_name, -O file_name

	   The name of the output file. The default is errmsg.sys.

       o   --statefile=file_name, -S file_name

	   The name for the SQLSTATE header file. The default is sql_state.h.

       o   --version, -V

	   Display version information and exit.
