How to export a MySQL database using the command line in Debian or Ubuntu

The command to export the database in mysql using the command line is mysqldump. The mysqldump command should come with any installation of mysql or mariadb

The format to use it is as follows:

Mysqldump-u username-p database_name > output_file.sql

For example, if you have a mysql user name named "testuser" and a database named "sample_database", you can back up the mysql database "sample_database" using the following command.

Mysqldump-u testuser-p sample_database > output_file.sql

Note that I call the output sample_database_output.sql, but you can name it as you like. ) after entering the above command, you will be prompted for the user's MySQL password.

The following screenshot shows what the above command should look like:
