#!/bin/bash
date=`date +%Y-%m-%d`

database=`mysql -uroot -p123456 -e "show databases;" | grep -v Database`

for db in $database
do
        [ -d /opt/$date/$db ] || mkdir -p /opt/$date/$db

        mysqldump -uroot -p123456 --skip-lock-tables $db > /opt/$date/$db.sql
        table=`mysql -uroot -p123456 -e "show tables from $db" | grep -v Tables`
        for t in $table
        do
                mysqldump -uroot -p123456 --skip-lock-tables $db $t > /opt/$date/$db/$t.sql
        done
