Ok, once again, the syntax is:
mysqladmin -u username --password=yourpassword <commands>
This means when you type it, you need a single '-' (minus sign, dash, whatever) in front of u. Then a space and your username. Then a space, two dashes, the word "password" followed by an equal sign, followed by your actual password, followed by whatever commands you need to run.
If this still doesn't make sense, do a
mysqladmin -?
It will should you all the options and commands and their syntax. There are two ways to do the username and password.
For username it is either:
-u username or
--user=username
and for password it is either:
-p password or
--password=yourpassword
Please note, it must be a lowercase p, otherwise it thinks you are talking about a port number.
Again, if it won't work still, take a look at
mysqladmin -?
You should be able to copy the statement I gave you before and just change the username and password to the correct values and it should work. But the punctuation, capitalization, spacing and spelling need to stay the same.
