I am using this command for a cron job to backup my database:

Code:
0 0 * * * mysqldump --opt -localhost-uusername -ppassword database >/path/to/backup/nl_%m%d%y.sql
I get this in return through e-mail:

Code:
mysqldump: unknown option '-o'
What can I do to get this to work?

BTW, I am using CPanel to edit this.
