Export all data from a MySQL/MariaDB database to CSV files

Bash script to export all data from a MySQL/MariaDB database to CSV files:

#!/bin/bash

DB_USER="your_username"
DB_PASS="your_password"
DB_NAME="your_database"

TABLES=$(mysql -u$DB_USER -p$DB_PASS -e "USE $DB_NAME; SHOW TABLES;" | grep -v "Tables_in")

for TABLE in $TABLES; do
    mysql -u$DB_USER -p$DB_PASS -e "USE $DB_NAME; SELECT * FROM $TABLE;" | sed 's/\t/","/g;s/^/"/;s/$/"/' > "$TABLE.csv"
done

echo "CSV export complete!"

Replace your_username, your_password, and your_database with your actual database credentials and database name. Save the script to a file, make it executable with chmod +x scriptname.sh, and then run it using ./scriptname.sh in your terminal. This script will create a CSV file for each table in your database, containing all the data from that table.
