把mysql查询结果保存到文件的shell脚本

该脚本是先删除已经存在的文件，然后后台执行SQL语句将其执行结果以一定的格式写入文件

复制代码

代码如下:#!/bin/bash

if [ -f “/var/lib/mysql/hell.txt” ]; then

rm -f /var/lib/mysql/hell.txt

echo “delete /var/lib/mysql/hell.txt” >> hell.txt

fi

mysql -uroot -plab <

use home;

select YongHuID,XueYuanID into outfile ./hell.txt fields terminated by | lines terminated by rn from sns_home_user where YongHuID < 20;
