如何批量检查表并进行repair,optimize

#!/bin/bash

host_name=192.168.0.123
user_name=xiaomo
user_pwd=my_pwd 
database=my_db_name
need_optmize_table=true
tables=$(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "show tables")

for table_name in $tables
do
 check_result=$(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "check table $table_name" | awk '{ print $4 }')
 if [ "$check_result" = "OK" ]
 then
 echo "It's no need to repair table $table_name"
 else
 echo $(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "repair table $table_name")
 fi

 # 优化表,可提高性能
 if [ $need_optmize_table = true ]
 then
 echo $(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "optimize table $table_name")
 fi
done
