mysqld & Options

If you want to run the 'mysqld' command with its options, don't forget that you need 

'mysqladmin -u [username] -p[password] mysqld --[option]...'

You need to do the mysqladmin...username stuff or it won't work.  Yes, this seems common sense, but no one ever explains this part.  This is, also, an instruction for Windows command prompt and not mysql.
