If you've set up SSH access for a package then you can run the following command-line instructions to import a MySQL database:
mysql -h hostname -u username -p username < databasefile.sql
The above command connects to your database with the -h (hostname) -u (username) -p (database name in this case) then the unzipped file < databasefile.sql
You will then be prompted to enter a password for the database. Input the password and press enter.
If the database file is zipped then you will need to unzip it first, then you can use one of the following commands:
For a .zip file you can use the unzip command:
For a .gz file you can use the gunzip command:
