Say you have a mysql server and have a long list of sql files to import in a specific order. Some files are 20kb some are 400Mb phpmyadmin will keel over and die, all that stress is just unnecessary.
at bash/terminal console execute this.
mysql -p123456 -h superserver megabase < /var/SQL/256.sql && mysql -p123456 -h superserver megabase < /var/SQL/257.sql
Explanation:
mysql= execute mysql command if at terminal or bash.
-p= the password flag, NOTE the password is supplied without a space.
-h= the host flag, the host is superserver.
megabase = the database that the sql will be imported into.
< = the import switch
/var/SQL/256.sql = the full path to the sql file.
&& = executes the next command only if the preceding command does not fail.
as show above you can chain 2 or even 100 import sql files.

I want to say – thank you for this!
