[MYSQL] logs exit error for mysqldump

Hi,
I used mysqldump in a script.
But I want log the error of my mysqldump.
For exemple: when I launch my script :dump.sh
I have the error on my console :

Code:

mysqldump: Got error: 1045: Access denied for user '-padmin'@'localhost' (using password: NO) when trying to connect

But I want save this error in a file (dump.log for exemple).
How Can I do it?

thanks

sh dump.sh 2>error.log
But if you how another solution, you can give it.
