trying to do it,

can;t do it in phpmyadmin

trying to do it in shell using

mysql -u dime_succexss -p dime_succexss < db_backup_2010-01-25.sql


but I don't think its working. Are there any other ways of doing it?

You can import the database by firing the below mentioned command:

mysql –u [root username] –p [root password] databasename < path to sql backup file [/home/username/backup.sql]

mysql -u dime_succexss -p dime_succexss < db_backup_2010-01-25.sql


but I don't think its working

It should be.
If you don't see anything, then it means it's working.

When you fetch the mysql cli with datas that way, you don't have any feedback until there is an error or everything is finished.

might be a permissions error, try chmod 777 on the .sql file

Is Navicat / MySQL Admin not an option? I always use Navicat with large SQL files
