This command is used to generate a backup of a MySQL database using the mysqldump utility. Here's a breakdown of the components:
mysqldump
: It is the command-line tool provided by MySQL to create logical backups of databases.-u ${user_name}
: It specifies the username to be used for authentication while connecting to the MySQL server.${user_name}
is a placeholder that should be replaced with the actual username.-p
: It prompts for a password while connecting to the MySQL server. After executing this command, you'll be asked to enter the password for the provided username.${db_name}
: It represents the name of the database to be backed up.${db_name}
is a placeholder and should be replaced with the actual name of the database you want to dump.> ${file_name}
: It is used to redirect the output of themysqldump
command to a file instead of displaying it on the terminal.${file_name}
is a placeholder that should be replaced with the desired filename for the backup file.
When you run this command, it connects to the MySQL server using the provided username and prompts for the password. Once authenticated, it creates a backup (dump) of the specified database and saves it to the file specified by ${file_name}
