Sometimes we need to to dump all databases form a MySQL server. This can be done using the mysqldump utility with the --all-databases switch enabled. In this case mysqldump will dump all databases to the standard output or to a file if explicitly specified. Let’s assume a situation where we want to backup all of the databases from the server, with the possibility to restore only one database at a time. To achieve this, you need to dump all the databases one by one or to use a pre-made script to do the heavylifting for you.
