Thanks all for your ideas.
I now have it fixed and it works from the script.

why are you specifying the password option twice ?
You probably need to specify a user as well ( -u option ) when you
execute mysqldump from the command line it will use your shell user as
the mysql user.
If you execute this from a cron job it will try to use the background
user ... whoever/whatever that is on your system
you might wanna try
Makes it easier to recreate/copy the database to somewhere else
You may need this option which quotes field names table names that may
be reserved words. Whcih can be the case if you're accessing a third
party database where they havent been to careful about observing naming
standards. If you dont, then your restores will fail with reserved word
heres a chunk of my db backup script (edited)
for database in `ls /var/lib/mysql`; do
if [ -d /var/lib/mysql/$database ]; then
/usr/bin/mysqldump -uUSERIDHERE -pPASSWORDHERE --add-drop-table
--allow-keywords $database > /BACKUPDIR/mysql/$database.sql
it works ... every night (and restores too)
Finally, there are some good examples on the mysql.com site .. have you
tried any of those??
