mysql under unix in batch mode

[Marianadin, Didier]

Hi,
 
I want to execute a simple query in batch mode in a mysql database.
my OS : Unix (solaris 2.6)
 
when I run this command : 
mysql -h localhost -u root -p mysql < did.query > did.out
 
I'm always asked password even if I've already specified it in the previous
command line (mysql)
Enter password:
 
How to avoid it ?
