需求除了导数据外, 有时候还要导出用户授权信息.而官方的show grants 命令一次只能查询一个用户SHOW GRANTS [FOR user]常用的做法就是写脚本, 但这么个小事情还专门写脚本就太麻烦了...实现我们可以通过如下SQL得到查询所有用户授权信息的SQLselect concat('show grants for "',user,'"@"',host,'";') from mysql.user;...但这样不符合自动化的要求.于是我们小改一下echo """select concat('show grants for \"',user,'\"@\"',host,'\";') from mysql.user...再小小的优化一下MYSQL_CONN="mysql -h127.0.0.1 -P3308 -p123456 -NB"echo """select concat('show grants for \"',
