I want to create a new user in MySQL and give it full access only to one database, say dbTest, that I create with a command like create database dbTest;. What would be the MySQL commands to do that?

# Create user in MySQL/MariaDB.
mysql-create-user() {
  [ -z "$2" ] && { echo "Usage: mysql-create-user (user) (password)"; return; }
  mysql -ve "CREATE USER '$1'@'localhost' IDENTIFIED BY '$2'"
}

# Delete user from MySQL/MariaDB
mysql-drop-user() {
  [ -z "$1" ] && { echo "Usage: mysql-drop-user (user)"; return; }
  mysql -ve "DROP USER '$1'@'localhost';"
}

# Create new database in MySQL/MariaDB.
mysql-create-db() {
  [ -z "$1" ] && { echo "Usage: mysql-create-db (db_name)"; return; }
  mysql -ve "CREATE DATABASE IF NOT EXISTS $1"
}

# Drop database in MySQL/MariaDB.
mysql-drop-db() {
  [ -z "$1" ] && { echo "Usage: mysql-drop-db (db_name)"; return; }
  mysql -ve "DROP DATABASE IF EXISTS $1"
}

# Grant all permissions for user for given database.
mysql-grant-db() {
  [ -z "$2" ] && { echo "Usage: mysql-grand-db (user) (database)"; return; }
  mysql -ve "GRANT ALL ON $2.* TO '$1'@'localhost'"
  mysql -ve "FLUSH PRIVILEGES"
}

# Show current user permissions.
mysql-show-grants() {
  [ -z "$1" ] && { echo "Usage: mysql-show-grants (user)"; return; }
  mysql -ve "SHOW GRANTS FOR '$1'@'localhost'"
}
